No full textA 0.12mm<sup>2</sup> Wien-Bridge Temperature Sensor with 0.1°C (3σ) Inaccuracy from -40°C to 180°C
No full text Resistor-based temperature sensors can achieve much higher resolution and energy efficiency than conventional BJT-based sensors [1], but they typically occupy more area (> 0.25 mm 2 ) and have lower operating temperatures (le 125 {circ} {C}) [2]-[4]. This work describes a 0.12mm 2 resistor-based sensor that uses a Wien-bridge (WB) filter to achieve 0.1 {circ} {C} (3 sigma) inaccuracy from - 40 {circ} {C} to 180 {circ} {C}. Compared to a state-of-the-art WB sensor [4], it occupies 6 × less area and achieves comparable relative accuracy over a 76% wider operating range.

Medium size (4.4 mm) (Fig. 8A). Ocellar triangle flat (Figs 8A, 8C). Scutum covered with reddish brown pruinescence, but prescutellar disc clearly contrasting with gray pruinescence and dc stripe of yellowishgray pruinescence (Fig. 8B). Legs with coxae, trochanters, basal 3/4 of fore and mid femora, hind femur and all tarsomeres 5 brown to reddish brown, hind tibia with brown ring at mid-length and hind tarsomere 1 brown with yellow base and apex, otherwise yellow (Fig. 8A); hind femur strongly swollen in males (about 2 x wider than in females), bearing 1AV series of spiniform bristles inserted on short tubercles (Fig. 8E). Wing sub-hyaline, pale brown; pterostigma brown, short and round, 1.5 x longer than wide, in between apices of R 1 and R 2+3, but only its posterior margin touching R 2+3 (Fig . 8D). Type material examined.

Holotype condition: good, but both antennae lost; not dissected. Additional material examined. BRAZIL. Amazonas: Careiro Castanho, BR-319, Km 181, Sítio São Paulo, 04°12′48″S 60°49′04″W, 13–27.vii.2016, Malaise grande 2, J.A. Rafael & F.F. Xavier F. (1 ♂, 1 ♀, INPA). Distribution. Brazil (Amazonas). Syneches applanatus is known to occur only in the Amazon biome (Fig. 50). Variation. Contrary to the males, the hind femora in females are not strongly swollen (Fig. 8F). Remarks. Syneches applanatus is similar to S. repletus due to the flat ocellar triangle, pterostigma brown and round, ending near apex of cell r 1 and hind femur strongly swollen in males. However, S. applanatus differs from S. repletus by the fore and mid femora mostly brown to reddish brown, hind tibia with a brown ring at mid-length and hind femur bearing 1AV row of spiniform bristles inserted on short tubercles. In S. repletus, the fore and mid femora are yellow, hind tibia is yellow lacking dark ring, but with the apical half to apical third brown and tubercles of the hind femur much longer than those of S. applanatus. The original description states that the prescutellar disc bears reddish brown pruinescence (Menezes & Ale-Rocha 2016), but examination of the holotype revealed that the prescutellar disc is covered with gray pruinescence, contrasting with the rest of the scutum.Published as part of Soares, Matheus M.

Rowella Lopes & Klautau 2023, GEN. NOV.

Type species: Leucettusa simplicissima Burton, 1932. Synonym: Leucetta – Poléjaeff, 1883: 28; non Haeckel, 1872: 117. Leucettusa – Dendy & Row, 1913: 738; Burton, 1963: 50; Borojević et al., 1990: 258; 2002: 1148; Hooper & Wiedenmayer, 1994: 481; Voigt et al., 2012: 11; Klautau et al., 2013: 454; Riesgo et al., 2018: 835. Etymology: Named after Dr Harold Row for his efforts on the systematics of calcareous sponges and for being the co-author of Leucaltidae. Diagnosis: Leucettidae with an amorphous or tubular massive body.The well-developed cortical skeleton can be comprised of single or multiple layers of triactines and/ or tetractines. The choanosomal and the atrial skeletons are comprised of pygmy triactines and tetractines. Aquiferous system leuconoid, syconoid or both. Remarks: Most of the species here assigned to RoƜella have a tubular body but several others can grow ramifications (e.g. R. simplicissima), while some have a pyriform or amorphous shape (e.g. R. pyriformis and R. dyctiogaster). More than the external morphology, every member of this genus has a peculiar spicule category, named primarily as pygmy triactines and/ or tetractines by Poléjaeff (1883: 67). These spicules are present in the choanosomal and atrial regions, in different proportions among species. We opt to follow Poléjaeff’s termination and refer to these spicules as pygmy in our descriptions. It is important to highlight that Leucaltis and RoƜella were not recovered as sister-taxa. Hence, pygmy spicules are different from the small choanosomal and atrial spicules of Leucaltis, differing from what was previously thought (e.g. Borojević et al., 1990). Pygmy spicules may have even a reduced actine (assuming a V-shape). As Poléjaeff (1883) just called them pygmy, not defining them, we are defining them by their size range (from 10.0–83.0 μm length to 2.5–13.0 μm width) and location scattered in the choanosomal and atrial skeletons. The presence of these morphological traits should be considered in the diagnosis of the genus. We could not resolve doubts on Leucettusa soyo (Hôzawa, 1933). This species had its position questioned in previous works (e.g. Dendy & Row, 1913; Rapp, 2004; Cavalcanti et al., 2013) and was allocated in different calcinean genera. Hôzawa’s (1933) description is doubtful, because important morphological characters, such as the presence of anastomosed tubes, were not clearly mentioned. He described a massive sponge, with radial choanocyte chambers around the atrium. Yet, he also mentioned the presence of ‘ascon-tubes’ and described the aquiferous system as ‘Dendy’s type D’ (Dendy, 1891), i.e. solenoid (Cavalcanti & Klautau, 2011). This is the only description available for this species and it is not satisfactory for its identification. We consider this a case of species inquirenda and highlight Cavalcanti et al. ’s (2013) statement that its position is uncertain and new material is necessary to make a proper genus assignment. Scope: Ten previously described ‘ Leucettusa ’ species are being transferred to the new genus RoƜella: R. connectens (Brøndsted, 1926); R. dictyogaster (Row & Hôzawa, 1931); R. haeckeliana (Poléjaeff, 1883); R. imperfecta (Poléjaeff, 1883); R. lancifera (Dendy, 1924); R. mariae (Brøndsted, 1926); R. pyriformis (Brønsted, 1926); R. simplicissima (Burton, 1932); R. tubulosa (Dendy, 1924) and R. Ʋera (Poléjaeff, 1883). Leucettusa nuda (Azevedo et al., 2009) is considered a junior synonym of R. simplicissima. Leucettusa soyo (Hôzawa, 1933) is considered species inquirenda.Published as part of Lopes, Matheus Vieira & Klautau, Michelle, 2023, Phylogeny and revision of Leucaltis and Leucettusa (Porifera: Calcarea), with new classification proposals and description of a new type of aquiferous system, pp. 691-746 in Zoological Journal of the Linnean Society 198 on pages 715-716, DOI: 10.1093/zoolinnean/zlad008, http://zenodo.org/record/789415
Stasis: study and translation of Sulpitius Victor\'s handbook
No full textEm nossa dissertação, estudamos o manual retórico de Sulpício Vítor, Institutiones Oratoriae. Nossa pesquisa é dividida em quatro partes. Na primeira, comentamos a bibliografia especializada que nos antecede, abordando questões importantes, como datação, ocorrência de alguns elementos retóricos e semelhança com outros manuais. Na segunda, comparamos os exemplos fornecidos por nosso autor com exercícios declamatórios, sobretudo os de Sêneca pai, mas também os de Calpúrnio Flaco e de Pseudo-Quintiliano. Na terceira, analisamos e explicamos a teoria dos estados de causa de Sulpício Vítor, comparando, sempre que possível, suas lições com as de outros textos. Na última, apresentamos uma tradução anotada para o português.In our dissertation, we study Sulpitius Victors rhetoric handbook, Institutiones Oratoriae. Our research is divided into four parts. The first consists of a commentary to the specialized bibliography that precedes us, addressing important issues, such as dating, occurrence of some rhetorical elements and similarities with other handbooks. The second aims to compare examples given by our author with declamation exercises, especially those ones of Seneca the Elder, but also the ones of Calpurnius Flaccus and of Ps. Quintilian. The third is dedicated to the analysis and elucidation of Sulpitius Victors issue-theory, as we compare, whenever possible, his lessons with the ones of other texts. The last includes an annotated Portuguese translation
