description: Ischyrothrips Schmutz
Ischyrothrips Schmutz, 1913: 1074. Type-species: Ischyrothrips crassus Schmutz, by subsequent designation, Priesner, 1949: 134.
The genus Ischyrothrips was described from Ceylon (= Sri Lanka) with four species, of which niger was synonymised with Ethirothrips stenomelas, obscurus was transferred to Ethirothrips (Mound & Palmer 1983) and spinosus was transferred to Dinothrips (Palmer & Mound 1978). As a result, crassus remained as the type-species of the genus. It is undoubtedly nearly allied to Ethirothrips and Machatothrips although the fore femur is relatively developed with 7–10 small tubercles on inner margin in both sexes, the pelta is tri-lobed and the fore tibia is ridged on inner surface with one or two apical tubercle(s). Machatothrips has similar fore femoral tubercles, but these are usually found in the female, and has a pair of long ocellar setae (= interocellar setae) as well as the pelta widely triangular. Ethirothrips has unarmed fore femora, but all the other character states are not distinguishable from this genus. Excluding the features of the fore legs, this genus is more similar to Ethirothrips than to Machatothrips, and it may appear that I. crassus is an unusual member of the genus Ethirothrips.

description: In this work we investigate the presence of scalar field models supporting kink solutions with logarithmic tails, which we call super long-range structures. We first consider models with a single real scalar field and associate the long-range profile to the orders of vanishing derivatives of the potential at its minima. We then present a model whose derivatives are null in all orders and obtain analytical solutions with logarithmic falloff. We also show that these solutions are stable under small fluctuations. To investigate the forces between super long-range structures, we consider three methods and compare them. Next, we study two-field models in which the additional field is used to modify the kinetic term of the other. By using a first-order formalism based on the minimization of the energy, we explore the situation in which one of the fields can be obtained independently from the other. Within this framework, we unveil how to smoothly go from long- or short- to super long-range structures.

(Figs 196–202, 245)
Ischyrothrips crassus Schmutz, 1913: 1076–1078.
This species has previously been known from Sri Lanka and India. Unfortunately, specimens from these two countries have not been available in this study. Two females and one male collected from Thailand listed below may represent I. crassus.
Diagnosis. Body dark brown, antennal segment III and fore tibiae slightly paler. Head (Fig. 196) about 1.6 times as long as broad, cheeks weakly constricted basally; eyes about 1/4 as long as head; postocular setae elongate, situated behind inner margins of eyes; postocellar setae short, situated behind posterior ocelli. Antennal segments III and IV subequal in length; segment VIII weakly constricted basally (Fig. 197). Maxillary stylets V-shaped, scarcely reaching postocular setae. Fore femora well developed, but smaller than head, each with 8–9 small tubercles arranged in a straight line along interior margin; fore tibia weakly ridged along interior margin, with one or two blunt inner apical tubercle(s); fore tarsal tooth stout, wide-based (Figs 198 & 199). Mesopresternum narrowly boat-shaped (Fig. 201). Pelta trilobed (Fig. 200). Tube (Fig. 202) a little longer than head in female. Male very similar to female, but smaller.
Specimens-examined. Thailand, Nakornprathom, Puttamonton, 2 females and 1 male, on dead branches, 18.ix.1991, P. Jangvitaya.

Remarks. The identity, and consequently the distribution of this species, is controversial due to its similarity with E. nigrocincta Denis, 1923 described from France, which was possibly introduced in many regions of the world (Christiansen 1963; Jordana 2012: 101; Katz et al. 2015: 18) or the species is in fact widely distributed. For this reason, I am considering here E. atrocincta sensu lato, as wide distribution (Christiansen 1963, Jordana 2012; Katz et al. 2015).

description: Polytrichothrips Priesner
Polytrichothrips Priesner, 1939: 77. Type-species: Polytrichothrips pilosus Priesner (= Docessissophothrips laticeps Bagnall), by monotypy.
The genus Polytrichothrips was described from Sarawak, Borneo, with unique species, P. laticeps. Subsequently, Mound (2007) described additional species, P. geoffri, from Queensland, Australia. The type-species has three pairs of long cephalic setae, the postoculars, postocellars and mid-vertexals, although geoffri has only one pair of long setae, the postoculars. Therefore, a combination of three morphological features seemed to characterise this genus until now: the maxillary stylets are deeply retracted to the level of the compound eyes and close together medially; the head has a pair of ommatidium-like structures on the cheeks ventro-laterally near base; the metanotum and pelta are scarcely sculptured. However, similar maxillary stylets and ommatidium-like structures are also found in Peltariothrips and Tarassothrips, though Peltariothrips has the shorter head with the maxillary stylets somewhat wider apart from each other in the middle of head. Tarassothrips has the ommatidium-like structures situated at the middle of cheeks, and has the unusually long sense-cones on the antennal segments. Moreover, Ethirothrips tenuis has the similar elongate maxillary stylets, and E. ommatus has the similar ommatidium-like structures situated behind the middle of cheeks. As a result, the genus Polytrichothrips is hardly distinguished among the Macrothripina by the peculiar weakly sculptured metanotum and pelta, and its generic status requires re-examining.

Bridging divides: translating the concept of sustainable livelihoods to rural Indonesia through institutional empowerment work
Creators: name: Bruggemann, I
name: Tracey, P
name: Kroezen, JJ
Publisher: name: Academy of Management
Year: 2018

description: This study delivers insights into how heterogeneous promoters and adopters of an idea can overcome asymmetries regarding their life- worlds and positions of power to achieve idea translation. Based on the case of the translation of the concept of sustainable livelihoods to Indonesia, which involved rural farmers and an international conservation NGO, we argue that translation involving heterogeneous actors requires multiple dimensions of institutional empowerment work jointly executed through promoters, adopters and boundary-spanning intermediaries. First, political empowerment work refers to building structures for the participation of the low- power stakeholders during translation, enabling adopters to actively contribute their perspectives. Second, social empowerment work relates to establishing relationships between promoters and adopters that support the process of translation, through addressing a lack of interpersonal trust and adopters’ identification with an idea. We contribute through developing a processual view of translation, which complicates the largely one-directional notion of translation prevalent in the literature. Furthermore, we present types of institutional work required to establish cooperation among heterogeneous actors, a dimension of work that has so far been understudied, and deliver insights into tackling grand challenges involving outsider-driven institutional change.

P. laticeps was originally described under the genus Docessissophothrips based on unique holotype female from Sarawak, Borneo. Subsequently, Priesner (1939) described the synonymous species Polytrichothrips pilosus also from Sarawak based on unique holotype female. This species is presumably known only from these holotypes, and we have not studied either of them. According to Mound and Palmer (1983) and the original descriptions, it is distinct among the genus in having elongate postocellar and mid-vertex cephalic setae.

Proironia

description: Proironia, new genus
DIAGNOSIS: Eyes virtually touching dorsally in male; antennal pedicel with fingerlike lobes extended into basal flagellomere on mesal and lateral surface; wing with membrane entirely glassy (no microtrichia); veins M 1 and M 2 with short to long stem (not connected directly to cell d); anal lobe of wing shallow; acrostichals numerous and scattered, not in rows.
TYPE SPECIES: P. gibbera, new species.
ETYMOLOGY: Pro - (first), and - ironia (from Ironomyia), in reference to the stem-group position of this extinct genus relative to Ironomyia. The genus name is feminine.
COMMENTS: The new genus is a stem group; it does not appear to have any features that are apomorphic with respect to Ironomyia and Cretonomyia (fig. 37). It seems preferable to have a separate genus for these two species, rather than expand the definition of the extant genus Ironomyia, which is quite apomorphic. Also, despite the list of differences between the two species, given in the diagnosis immediately below, they are actually quite similar. The most significant differences appear to be the orientation of crossvein dm-cu and length of M 1 -M 2 stem.

description: The possibility of topological phase transition with or without a magnetic flux trapped in the cells of a class of decorated lattices is explored in details.Using a tight binding Hamiltonian and a real space decimation scheme we analytically obtain the non-dispersive and dispersive energy bands, and exactly locate the eigenvalues at which energy gaps close.We find that despite the local breaking of the time reversal symmetry, as a magnetic field is turned on, the topological invariant exhibits quantization, and a clear appearance of edge localized modes is observed exactly at the gap-closing energy eigenvalues in the topologically non-trivial insulating phase.The bulk boundary correspondence is obeyed. The protection of the edge states by a chiral symmetry is confirmed for both the presence and absence of magnetic flux. Our studies have been extended to other kinds of decorated lattices where topological phase transition is possible only above a threshold value of the hopping integral describing these lattice. Our results are analytically exact.

Paratypes: same data as holotype, 1 male (NCA 2008 /2918); same data, 1 male (NCA 2008 /2911).
Diagnosis. This species is distinguished from other euophryines by the unique form of the chelicerae, with multicuspid teeth (Fig. 3). The structure of the palpal organ is similar to that in the genus Euophrys, but the embolic disc is larger. C. trifasciata differs from Asian species of this genus by the shape of the embolus and the proximal tegular lobe.
Etymology. The specific name refers to the colouration of the “cheeks” with three white stripes.
Description. Measurements. Cephalothorax: length 1.5–2.2, width 1.0–1.5, height 0.6–1.1. Abdomen: length 1.2–2.4, width 0.9–1.2. Eye field: length 0.6–1.1, anterior width 0.9–1.4, posterior width 0.8–1.3.
Male. General appearance as in Fig. 1. Carapace moderately high, dark brown, with median lighter stripe. Ocular area dark brown, almost black. Anterior eyes surrounded by small white scales, some brown bristles near first row of eyes. Sternum yellowish brown. Clypeus low, brown with white stripe at base of chelicerae. Three parallel lines composed of white hairs on “cheeks”, below anterior lateral eyes (Fig. 2). Chelicerae brown, proximal parts covered with long white hairs, promargin with four teeth, retromarginal tooth broad, with five to seven cusps (Fig. 3). Abdomen yellowish grey (mosaic of grey stains on light background), dorsum with black scutum covering half of abdomen (sometimes scutum poorly visible), venter also spotted. Legs dark brown, tarsi lighter. First pair bigger than others, patellae, tibiae and metatarsi with dense brown hairs ventrally. Three pairs of ventral spines on first tibia. Pedipalps yellow, covered with white hairs and sparse dark brown bristles (Fig. 2). Embolic disc large, bulb with long proximal lobe (Fig. 4), cymbium with small tutaculum (ear-shaped process at base on retrolateral side) (Fig. 5), retrolateral tibial apophysis simple and triangular (Figs 4–6).
Female unknown.
Distribution. Known only from Table Mountain in the Western Cape, South Africa.
Remarks. This is the first species of this genus discovered in Africa.

description: Euophrys C.L. Koch, 1834
Type species: Aranea frontalis Walckenaer, 1802
Description. Small to medium sized spiders, ranging from 2 to 5 mm in length. The male palp has a tibial apophysis that is often very thin and needle-shaped; embolus thread-like, coiled at the tip of the bulb (sometimes around a hollow pit or coiled within that pit), in some species the embolus forms a spiral, placed perpendicular or oblique to the long axis of the palp (sometimes parallel); sperm duct meandering, forming broad loops. The epigyne is weakly sclerotized, usually with two rounded or oval depressions separated by a median septum, with large oval spermathecae and the seminal duct with characteristic kinks in the majority of species. The abdomen in both sexes is usually dark, with a pattern consisting of a mosaic of small yellow reticulate markings on a blackish or dark grey background, sometimes also with darker chevrons or with a few pairs of small light dots, abdomen light ventrally with numerous small dark patches. Abdomen of males sometimes has a delicate scutum on the dorsal surface. Species of the genus Euophrys are rather difficult to distinguish, especially females.
Redescription of the type species is given in Logunov, Cutler & Marusik (1993) and Logunov (1997).
Distribution. Worldwide, except the Australian Region.

description: SUBFAMILY SCIADOCERINAE
DIAGNOSIS: Pretarsus with empodium either minute or completely lost. Acrostichals long, in 1–3 rows (except Ulrichophora). Plesiomorphic features include: cells cup and bm present (closed); frons without median sulcus; tip of R 4+5 fully fused to C; sternites fully developed in both sexes.
COMMENTS: There are two living sister species of Sciadocerinae, Archiphora patagonica Schmitz in Chile and Sciadocera rufomaculata White in Austalia and New Zealand. Their close relationship is indicated by characters 14 and 15 (table 4): stem of M 1 -M 2 lost or spectral, and the basal flagellomere is enlarged in males (it is much larger in Archiphora). A Baltic amber (Eocene) species was transferred to its own genus, Hennigophora robusta (Meunier), by Brown (2007a), into which I am also transferring Archiphora pria Grimaldi and Cumming (see below). Two other genera of sciadocerines occur in Baltic amber: Ulrichophora Brown (monotypic: lobata), and Eosciadocera Hong (two species). I have not examined Ulrichophora, but the fly has some distinctive features, the most striking being the numerous acrostichals not arranged into one or a few rows (Brown, 2007a). Eosciadocera setosa and E. pauciseta, n. sp., are striking because of their large size, nearly 7 mm in body length.

Hennigophora Brown, 2007a: 8. Type species Archiphora robusta (Meunier) (Baltic amber, fig. 19).
DIAGNOSIS: (From Brown, 2007a, with modifications in parentheses): Basal flagellomere of male relatively small (little differentiated from female); frons large, with frontal setae as in Archiphora patagonica (which has 1 pair interfrontal setae, 1 pair orbitals) (fig. 46B); scutum with large setae consisting of 1 median acrostichal row and 1 dorsocentral row on each side (fig. 19); stem of M 1 and M 2 well developed (tubular, but not sclerotized; fig. 46B); anal lobe small; empodium absent; (stridulatum present); male terminalia with separate surstylus on left side.
COMMENTS: Brown (2007a) placed Hennigophora robusta, Ulrichophora lobata, and “ Archiphora ” pria in a polytomy with Archiphora patagonica and Sciadocera rufomaculata. Based on the discovery of a new specimen of A. pria, which is better preserved than the original specimen/ holotype (AMNH NJ-773), I am transferring this species to Hennigophora, though this is essentially based on plesiomorphic resemblance.

description: Surveillance systems often struggle with managing vast amounts of footage, much of which is irrelevant, leading to inefficient storage and challenges in event retrieval. This paper addresses these issues by proposing an optimized video recording solution focused on activity detection. The proposed approach utilizes a hybrid method that combines motion detection via frame subtraction with object detection using YOLOv9. This strategy specifically targets the recording of scenes involving human or car activity, thereby reducing unnecessary footage and optimizing storage usage. The developed model demonstrates superior performance, achieving precision metrics of 0.855 for car detection and 0.884 for person detection, and reducing the storage requirements by two-thirds compared to traditional surveillance systems that rely solely on motion detection. This significant reduction in storage highlights the effectiveness of the proposed approach in enhancing surveillance system efficiency. Nonetheless, some limitations persist, particularly the occurrence of false positives and false negatives in adverse weather conditions, such as strong winds.

description: For the first time, 3D multiphysics finite element modelling has been used to optimise the geometry of a calorimetric thermal flow sensor. The model involves and couples three physics domains: electric, thermal and fluid mechanics. The model is validated against experimental data obtained from a thermoelectronic flow sensor comprising of a tungsten heating resistor and temperature sensing diodes. Upstream and downstream diodes measure the temperature change caused by the asymmetric thermal profile when gas flow is introduced. The optimum distance between the diodes and the heater is shown along with the advantages of altering heater and membrane geometries, providing the knowledge for application-driven sensor optimisation.
