description: Recently, Fang et al. have predicted a high ZT of 1.54 in TaSbRu alloys at 1200 K from first-principles without considering spin-orbit interaction, accurate electronic structure, details of phonon scattering, and energy-dependent holes relaxation time. Here, we report the details of structural stability and thermoelectric performance of Bi-Substituted p-type TaSbRu from first-principles calculations considering theses important parameters. This indirect bandgap semiconductor (Eg=0.8 eV by TB-mBJ+SOC) has highly dispersive and degenerate valence bands, which lead to a maximum power factor, 3.8 mWm-1K-2 at 300K. As Sb-5p has a small contribution to the bandgap formation, the substitution of Bi on the Sb site does not cause significant change to the electronic structure. Although the Seebeck coefficient increases by Bi due to slight changes in the bandgap, electrical conductivity, and hence, the power factor reduces to ~3 mW m-1K-2 at 300K (50% Bi). On the other side, lattice thermal conductivity drops effectively to 5 from 20 W/m K as Bi introduces a significant contribution in the acoustic phonon region and intensify phonon scattering. Thus, ZT value is improved through Bi-substitution, reaching 1.1 (50% Bi) at 1200 K from 0.45 (pure TaSbRu) only. Therefore, the present study suggests how to improve the TE performance of Sb-based half-Heusler compounds and TaSbRu (with 50% Bi) is a promising material for high-temperature applications.

description: Thermoelectric materials based on earth-abundant and non-toxic elements are very useful in cost-effective and eco-friendly waste heat management systems. The constituents of SrGaSnH are earth-abundant and non-toxic, thus we have chosen SrSnGaH to study its structural stability and thermoelectric properties by using DFT, DFPT, and semi-classical Boltzmann transport theory. Our elastic and phonons calculations show that the compound has good structural stability. The electronic structure calculation discloses that it is an indirect bandgap (0.63 eV by mBJ+SOC) semiconductor. Light band hole effective mass leads to higher electrical conductivity along x-axis than that of along z-axis. On the other side, the weak phonon scattering leads to high lattice thermal conductivity ~10.5 W m-1K-1 at 300 K. Although the power factor (PF) is very high along the x-axis (above 10 mW m-1K-2 at 300 K), such large kl dramatically reduces ZT. The maximum values of in-plane and cross-plane ZT are ~1 (n-type), 0.8 (p-type) and 0.6 (n-type), (0.2 p-type) at 700 K, respectively. The present study has revealed that this compound has strong potential in eco-friendly TE applications.

description: In this paper, we propose a modified formal Lagrangian formulation by introducing dummy dependent variables and prove the existence of such a formulation for any system of differential equations. The corresponding Euler--Lagrange equations, consisting of the original system and its adjoint system about the dummy variables, reduce to the original system via a simple substitution for the dummy variables. The formulation is applied to study conservation laws of differential equations through Noether's Theorem and in particular, a nontrivial conservation law of the Fornberg--Whitham equation is obtained by using its Lie point symmetries. Finally, a correspondence between conservation laws of the incompressible Euler equations and variational symmetries of the relevant modified formal Lagrangian is shown.

description: This Article focuses on the consequences of the acquisition of Cypriot citizenship through Cyprus's new Investment Programme, adopted in 2013. One of the criteria for the acquisition of citizenship is the investment of Euro two million in Cypriot banks, immovable property or companies which must be retained on Cypriot territory for at least three years. However, immovable residential property to a value of Euro 500,000 must be retained in Cyprus indefinitely or there is a risk of citizenship being revoked. These criteria raise concerns, particularly in light of EU law on citizenship and the free movement of capital. This Article analyses the possible violations of EU law in this context and argues against the conditional nature of the citizenship provided by the Programme, which results in violation of the free movement of capital and restricts the genuine enjoyment of the status of EU citizenship. Case law by the Court of Justice and academic literature analysing the right to the free movement of capital and revocation of citizenship in an EU context will be examined to determine the repercussions of the Cyprus Programme. This topic is extremely relevant today, as it sheds light on the developing nature of EU citizenship and the relationship between EU citizenship rights weighed against the national interests of the Member States.

description: Unmanned aerial vehicles (UAVs) have the potential to overcome the deployment constraint of Internet of Things (IoT) in remote or rural area. Wirelessly powered communications (WPC) can address the battery limitation of IoT devices through transferring wireless power to IoT devices. The integration of UAVs and WPC, namely UAV-enabled Wireless Powering IoT (Ue-WPIoT) can greatly extend the IoT applications from cities to remote or rural areas. In this article, we present a state-of-the-art overview of Ue-WPIoT by first illustrating the working flow of Ue-WPIoT and discussing the challenges. We then introduce the enabling technologies in realizing Ue-WPIoT. Simulation results validate the effectiveness of the enabling technologies in Ue-WPIoT. We finally outline the future directions and open issues.

Australian Indigenous policy in the neoliberal age: reassessing 'Indigenous' responsibility
Creators: name: Dornan, Paul J.
Publisher: name: Swinburne
Year: 2024

description: Neoliberal policy proscriptions are one part of a wider dialectic of domination that shapes indigenous/settler relations within Australia. This dialectic includes hegemonic processes of social and material domination, resulting in the imposition of a narrative that focuses on `responsibility', imposes neoliberal economics, and apportions `blame' for disadvantage on Indigenous communities through an agreement-making regime that relies on `consent' to appropriate Indigenous cultural identity. This thesis explores how this neoliberal notion of responsibility restricts possibilities for genuine reconciliation before offering differentiated citizenship as a possible way forward.

description: EU citizenship played a central role in the debate preceding the Brexit referendum and during the Brexit negotiations. It is inevitable, therefore, that, in the context of Brexit the concept of EU citizenship was and continues to be deeply challenged. This Special Section takes the process of Brexit and the challenges raised against the process of European integration in this context as an invitation to critically reflect on the current state of EU law by focusing, more particularly, on the concept of EU citizenship.

description: The purpose of this paper is to introduce two semiparametric methods for the estimation of copula parameter. These methods are based on minimum Alpha-Divergence between a non-parametric estimation of copula density using local likelihood probit transformation method and a true copula density function. A Monte Carlo study is performed to measure the performance of these methods based on Hellinger distance and Neyman divergence as special cases of Alpha-Divergence. Simulation results are compared to the Maximum Pseudo-Likelihood (MPL) estimation as a conventional estimation method in well-known bivariate copula models. These results show that the proposed method based on Minimum Pseudo Hellinger Distance estimation has a good performance in small sample size and weak dependency situations. The parameter estimation methods are applied to a real data set in Hydrology.

(Figs 4, 17)
 Type material. Holotype (Figs 4, 17): male, “SW Thailand | Chumphon [Province], 162m | Pa Toh, Ban Lang Tang | 9°46'5''N, 98°46'59''E | 3. V. 2008 leg. K. Černý ” / “Slide | AV2593 ♂ | A. Volynkin ” (MWM/ ZSM, ex CKC).
 Paratype: THAILAND: male, the same data as in the holotype (CKC).
 Diagnosis. The forewing length is 7.5 mm in males. Miltochrista banlanga sp. n. (Fig. 14) is externally very similar to M. ranonga sp. n. (Figs 5–7) but distinguished by the discal spot of the forewing fused with the medial line. The male genitalia structure of the new species (Fig. 17) is most similar to M. phupana sp. n. (Figs 15, 16), from which M. banlanga sp. n. differs externally in the more arcuate medial line and the discal spot being fused with the medial line. In the male genital capsule, M. banlanga sp. n. is different from M. phupana sp. n. in its longer vinculum, the broader valva, and the somewhat shorter distal costal and saccular processes. The phallus of the new species is slightly narrower than in M. phupana sp. n. and has a somewhat shorter and narrower carinal crest. The vesica configurations of the two species are similar but in M. banlanga sp. n., the cornuti are longer than in M. phupana sp. n., and the lateral one is markedly longer than the distal one whereas the cornuti of M. phupana sp. n. are equal in length. The detailed comparison with M. ranonga sp. n. is provided below in the diagnosis of this species.
The female is unknown.
 Distribution. Southern Thailand (Chumphon Province).
 Etymology. The specific epithet is derived from the type locality of the new species. The name is a noun in nominative singular in apposition to the generic name.

description: The UK has been a main "winner" in European higher education. In the European Higher Education Area, the UK has successfully exported its higher education model to the other EU Member States and beyond, without conceding powers to the EU in that regard. It reaped the benefits of an enlarged higher education "market" on which its higher education institutions could successfully compete, at minimal administrative, political or other cost. Furthermore, in EU higher education law and policy, the UK has occupied an equally advantageous position. The UK has been very successful in obtaining EU research funding. This could potentially be linked to its brain-gain in being a major net importer of mobile EU students, researchers and academics. At the same time, because of its fee-paying model, this imported talent has come at a very low cost, as EU law on student mobility and diploma recognition has worked mainly to the benefit of the UK model by requiring equal treatment as regards tuition fees but not maintenance grants. This Article explores the impact that Brexit may have on European higher education and the UK's position within it, and vice-versa. It will argue that the UK's current strength in higher education may be one of its weak spots in the Brexit negotiations.

 Type material. Holotype (Figs 5, 18): male, “SW Thailand | Ranong-prov, Ranong, 380m | 10°01'32''N, 98°40'13'' E | 3.–4. XII.2005 leg. K. Černý ” / “Slide | AV2594 ♂ | A. Volynkin ” (MWM/ ZSM, ex CKC).
 Paratypes. THAILAND: 6 males, the same data as in the holotype, gen. prep. Nos.: AV2595 ♂, AV3409 ♂ (CKC); 1 female, Ranong [Prov.], Ranong, 380m, 10°01'32''N 98°40'13''E, 17, 20.XI.2006, K. Černý leg. (CKC).
 Diagnosis. The forewing length is 7.0–7.5 mm in males. The typical specimens of M. ranonga sp. n. (Figs 5, 6) are externally very similar to M. banlanga sp. n. but differ in the discal spot of the forewing separated from the medial line. The reliable identification of the form lacking the medial line (Fig. 7) requires the examination of the genitalia structures. The male genital capsule of the new species (Figs 18, 19) can easily be distinguished from M. banlanga sp. n. (Fig. 17) due to the strongly shield-like dilated proximal section of the uncus, which is only slightly dilated in the congener. The similarly proximally dilated uncus is known in the externally dissimilar M. roseogrisea (Figs 8, 9, 21, 25), M. uncalis (Figs 10, 11, 22, 26), and M. asphida (illustrated by Volynkin et al. (2023)), but the new species differs clearly from these species in many aspects of its male genitalia structures. Additionally, unlike M. banlanga sp. n., the valva of M. ranonga sp. n. has a somewhat thicker distal costal process. The phallus of M. banlanga sp. n. is somewhat longer and broader than in M. ranonga sp. n. Compared to M. ranonga sp. n., the vesica of the new species is somewhat shorter, and has a larger lateral diverticulum bearing a markedly longer cornutus.
The female is unknown.
 Distribution. Southern Thailand (Ranong Province).
 Etymology. The specific epithet is derived from the province of Ranong in Southern Thailand, where the new species is found. The name is a noun in nominative singular in apposition to the generic name.

Federated Identitiy Management

description: The Secure Shell Protocol (SSH) is the de-facto standard for accessing remote servers on the
commandline. Use cases include remote system administration for unix administrators, git via ssh
for developers, rsync via ssh for system backups, and HPC access for scientists. Unfortunately,
there is no globally accepted usage pattern for federated usage yet.
The large variety of users with different backgrounds and usage profiles motivated us to develop
a set of different tools for facilitating the integration with federated user identities. The main
novelty of our contribution is the integration of an ssh Certificate Authority (CA) into the existing
motley-cue + oidc-agent mechanism via a toolchain that we call "oinit". It simplifies the usage
of ssh certificates by leveraging authorisation information via established federation mechanisms.
The benefit is that – after an initial setup step – ssh may be used securely without interrupting
existing flows. This allows for example the use of rsync or git via ssh.
To enable this, oinit consists of a collection of programs to enable OpenSSH login for federated
identities based on certificates:

• The oinit-ca provides a REST interface to an ssh-ca at which authorised users obtain an
ssh certificate for a specified host or host group. Authorisation decisions are enforced by
motley-cue, the component that maps federated identities to local ones on the ssh server
side. User provisioning may also be triggered at this point, e.g. via motley-cue and feudal.
• Users employ the oinit tool to add hosts to the oinit mechanism. Once established, ssh
certificates will automatically be retrieved, whenever this may be necessary and stored in
the ssh-agent.
• Serverside tools and configuration for enabling ssh without knowledge of local usernames
("non-username operation"), which is particularly useful in federated scenarios.
In this paper we outline the basic solution and focus on on user interface optimisation with
the integration of ssh certificates.

description: This Article addresses questions concerning the loss of Member State nationality and the possible implications for EU citizenship. The Author first revisits Rottmann (Court of Justice, judgment of 2 March 2010, case C-135/08) and reflects on the limitations that EU places on decisions of Member States to deprive a person of his/her nationality. In addition, the contribution considers whether the Rottmann case law, and the logic underpinning it, can be extended to situations in which Member State nationality is lost as a result of a decision of a Member State to withdraw from the Union. Having answered the latter question in the negative - for UK nationals Brexit implies loss of EU citizenship - the author briefly discusses the recent proposal to introduce an associate EU citizenship for nationals of former Member States.
Extraordinary thermoelectric performance of ABaX compared to Bi$_2$Te$_3$

description: Thermoelectric materials can generate electricity directly utilizing heat and thus, they are considered to be eco-friendly energy resources. The thermoelectric efficiency at low temperatures is impractically small, except only a few bulk materials (Bi$_2$Te$_3$ and its alloys). Here, I predict two new thermoelectric materials, LiBaSb and NaBaBi, with excellent transport properties at low-medium temperature by using the first-principles method. The relatively low density of states near Fermi level, highly non-parabolic bands, and almost two times wider bandgap of NaBaBi lead to almost two times higher anisotropic power factor at 300K than that of Bi2Te3. On the other side, almost similar phonon density of states and anharmonicity of NaBaBi cause almost identical lattice thermal conductivity (but it is much higher in LiBaSb). These effects make it a superior thermoelectric material, with a predicted cross-plane (in-plane) ZT ~2 (~1) at 300 K for both n- and p-type carriers, even higher (~2.5 for p-type) at 350K. On the other hand, the isotropic maximum ZT of NaBaBi is ~1.2 and 1.6 at 350K for n and p-type carriers, respectively. However, LiBaSb is less suitable for low-temperature TE applications, because of its relatively wider bandgap and high lattice thermal conductivity.

description: Subspace clustering is a class of extensively studied clustering methods where the spectral-type approaches are its important subclass. Its key first step is to desire learning a representation coefficient matrix with block diagonal structure. To realize this step, many methods were successively proposed by imposing different structure priors on the coefficient matrix. These impositions can be roughly divided into two categories, i.e., indirect and direct. The former introduces the priors such as sparsity and low rankness to indirectly or implicitly learn the block diagonal structure. However, the desired block diagonalty cannot necessarily be guaranteed for noisy data. While the latter directly or explicitly imposes the block diagonal structure prior such as block diagonal representation (BDR) to ensure so-desired block diagonalty even if the data is noisy but at the expense of losing the convexity that the former's objective possesses. For compensating their respective shortcomings, in this paper, we follow the direct line to propose Adaptive Block Diagonal Representation (ABDR) which explicitly pursues block diagonalty without sacrificing the convexity of the indirect one. Specifically, inspired by Convex BiClustering, ABDR coercively fuses both columns and rows of the coefficient matrix via a specially designed convex regularizer, thus naturally enjoying their merits and adaptively obtaining the number of blocks. Finally, experimental results on synthetic and real benchmarks demonstrate the superiority of ABDR to the state-of-the-arts (SOTAs).

description: Tremendous efforts have been devoted to the search for exotic topological states, which usually exist at an interface between lattices with differing topological invariants according to the bulk-edge correspondence. Here, we show a new finding of topological states localized at the interface between two gauge-shifted Floquet photonic lattices, despite the same topological order across the entire structure. The quasienergy band structures reveal that these new interface modes belong to the Floquet π modes, which are further found to enable a robust one-way propagation thanks to the flexible control of the Floquet gauge. The intriguing propagations of these π-interface modes are experimentally verified in a silicon waveguides platform at near-infrared wavelengths, which show both broad working bandwidth and high tolerance to the structural fluctuations. Our approach provides a new route for light manipulations with robust behaviours in Floquet engineering and beyond.

description: Clustering mixed data presents numerous challenges inherent to the very heterogeneous nature of the variables. A clustering algorithm should be able, despite of this heterogeneity, to extract discriminant pieces of information from the variables in order to design groups. In this work we introduce a multilayer architecture model-based clustering method called Mixed Deep Gaussian Mixture Model (MDGMM) that can be viewed as an automatic way to merge the clustering performed separately on continuous and non-continuous data. This architecture is flexible and can be adapted to mixed as well as to continuous or non-continuous data. In this sense we generalize Generalized Linear Latent Variable Models and Deep Gaussian Mixture Models. We also design a new initialisation strategy and a data driven method that selects the best specification of the model and the optimal number of clusters for a given dataset "on the fly". Besides, our model provides continuous low-dimensional representations of the data which can be a useful tool to visualize mixed datasets. Finally, we validate the performance of our approach comparing its results with state-of-the-art mixed data clustering models over several commonly used datasets.

However, a theory that can explain the rationale why the linear PID can successfully deal with the ubiquitous uncertain nonlinear dynamical systems and a method that can provide explicit design formulae for the PID parameters are still lacking. This paper is a continuation of the authors recent endeavor towards establishing a theoretical foundation of PID. We will investigate the rationale of PID control for a general class of high dimensional second order non-affine uncertain systems. We will show that a three dimensional parameter set can be constructed explicitly, such that whenever the PID parameters are chosen from this set, the closed-loop systems will be globally stable and the regulation error will converge to zero exponentially fast, under some suitable conditions on the system uncertainties. Moreover, we will show that the PD(PI) control can globally stabilize several special classes of high dimensional uncertain nonlinear systems. Furthermore, we will apply the Markus-Yamabe theorem in differential equations to provide a necessary and sufficient condition for the choice of the PI parameters for a class of one dimensional non-affine uncertain systems. These theoretical results show explicitly that the controller parameters are not necessary to be of high gain, and that the ubiquitous PID control does indeed have strong robustness with respect to both the system structure uncertainties and the selection of the controller parameters.

description: The Upper Penticton Creek Watershed Experiment is one of a handful of forestry-focused pairedcatchment experiments in the snow-dominated zone of western North America. The study involves an undisturbed control catchment and two treatment catchments. Streamflow has been monitored at weirs on all three streams since 1985. Following a pre-harvest monitoring period, the treatment catchments were subject to clearcut harvesting in multiple passes that cumulatively covered ~50% of the catchments. In addition to streamflow, available hydrometeorological data sets include weather observations, snowpack water equivalent, rainfall interception, soil water content, and water table levels in soil piezometers and bedrock wells. The data archive also includes digital elevation models, a Lidar-derived image of tree heights in 2016, and vector data associated with lakes and reservoirs, the stream network, clearcut boundaries, a soil map and the logging road network. Together, these data sets provide a basis for empirical analyses of hydrological response to forest dynamics and climatic variability, and for calibration and testing hydrological models using internal variables. They should also provide useful data sets for educational purposes.

description: The demand for green energy increases day by day due to environmental concern and thermoelectric (TE) materials are one of the eco-friendly energy resources. Few authors reported high TE performance in TmCu$_3$Ch$_4$, reaching the figure of merit (ZT) above 2 at 1000K, from first-principles calculations neglecting electron-phonon scattering, spin-orbit coupling effect (SOC), and energy-dependent carrier lifetime. Here, thermoelectric transport properties of TmCu$_3$Ch$_4$ are reinvestigated through considering these parameters, and significant discrepancies are found. The ZT of p-type TaCu$_3$Te$_4$ can reach ~3 at 1000K among these compounds due to its low lattice thermal conductivity ($κ_l$) (0.38 W m-1 K-1). Interestingly, the value of $κ_l$ is reduced to 0.17 W m-1 K-1 through 1 GPa pressure while the power factor is slightly improved due to bandgap reduction, leading to an extraordinary ZT~5.5 at 1000K. Although the substitution of Se causes a slight reduction of $κ_l$ to ~0.3 W m-1 K-1, the power factor is reduced significantly due to the dramatic reduction of DOS near Fermi level, which leads to lower the Seebeck coefficient largely and increase electrical conductivity slightly.
WORKING PAPER 10 - Spaces of Memory: the construction of colonial and post-colonial spaces in the memories of former Portuguese colonizers

description: Abstract The question of the intricate relation between memory and history has become even more problematic in the post-colonial condition. The role of memory in the shaping of history, understood as a strategic reading of the past, is now a deeply contested one, for we are confronted with plural, conflictive and politicized narratives, which erupted from the identities that co-existed in the tensional field of colonial power relations. My paper addresses a segment of this new landscape, focusing on the memories built by former Portuguese colonizers who occupied different positions in the structure of colonial power. I question the strategies of nostalgia and resentment and the work of mourning that are ingrained in those memories. They will also be considered in their close relation to the imaginary construction of colonial and post-colonial spaces since they disclose particular representations of Portugal, Angola, and Mozambique as sites for identity-building, which symbolically extend the motherly body and the family relationships (Mother-Father/Child). Cleavages between "good" and "bad" spaces, but also the ambivalent swaying between the two, are pervasive in the memories analyzed in this paper.

description: Using a generalisation of the classical notion of Dirichlet-to-Neumann map and the related formulae for the resolvents of boundary-value problems, we analyse the asymptotic behaviour of solutions to a "transmission problem" for a high-contrast inclusion in a continuous medium, for which we prove the operator-norm resolvent convergence to a limit problem of "electrostatic" type for functions that are constant on the inclusion. In particular, our results imply the convergence of the spectra of high-contrast problems to the spectrum of the limit operator, with order-sharp convergence estimates.

description: Metabolites of di-(2-ethylhexyl) terephthalate (DEHTP), a substitute for ortho-based phthalate plasticisers like di-(2-ethylhexyl) phthalate (DEHP), were analysed in 2112 first-morning void urine samples from children and adolescents aged 3-17 years, participating in the population representative German Environmental Survey on Children and Adolescents, GerES V 2014-2017. The major metabolite 5cx-MEPTP was detected in all urine samples with a geometric mean (GM) of 7.39 (my)g/L, with highest levels in the mg/L range. The GM for the other metabolites were 0.55 (my)g/L for 5OH-MEHTP, 0.54 (my)g/L for 5oxo-MEHTP and below the limit of quantification (LOQ) for 2cx-MMHTP. As already observed for other plasticisers and their substitutes, the youngest children (3-5 years) had 2-2.5-fold higher urinary DEHTP metabolite levels compared to 14-17 years old adolescents. High urinary levels of DEHTP metabolites were associated with high DEHTP concentrations in house dust. None of the samples analysed exceeded the toxicologically derived German human biomonitoring guidance value (HBM-I-Value) of 1.8 mg/L for 5cx-MEPTP. Comparison with DEHTP levels reported in other HBM studies worldwide confirmed a widespread exposure of children, adolescents and adults, with considerably higher exposures (2.6-7 fold) reported in the United States. In GerES V, exposure data for 12 different phthalates and the phthalate substitute DINCH were generated as well. Together with the data for DEHTP presented in this manuscript, GerES V allows a current and comprehensive overview on the concurrent exposure of German children and adolescents to common plasticisers. Further evaluation of aggregate exposure characteristics shall support efforts to reduce chemical hazard burden from plasticisers in Germany and beyond. © 2020 The Author(s).

description: Researchers continue to be interested in exploring the effects that covariates have on the heterogeneity in trajectories. The inclusion of covariates associated with latent classes allows for a more clear understanding of individual differences and a more meaningful interpretation of latent class membership. Many theoretical and empirical studies have focused on investigating heterogeneity in change patterns of a univariate repeated outcome and examining the effects on baseline covariates that inform the cluster formation. However, developmental processes rarely unfold in isolation; therefore, empirical researchers often desire to examine two or more outcomes over time, hoping to understand their joint development where these outcomes and their change patterns are correlated. This study examines the heterogeneity in parallel nonlinear trajectories and identifies baseline characteristics as predictors of latent classes. Our simulation studies show that the proposed model can tell the clusters of parallel trajectories apart and provide unbiased and accurate point estimates with target coverage probabilities for the parameters of interest in general. We illustrate how to apply the model to investigate the heterogeneity in the joint development of reading and mathematics ability from Grade K to 5. In this real-world example, we also demonstrate how to select covariates that contribute the most to the latent classes and transform candidate covariates from a large set into a more manageable set with retaining the meaningful properties of the original set in the structural equation modeling framework.

description: Abstract The implementation of a structural adjustment program in a war damaged Mozambique in 1987 had devastating consequences for the majority of the population. As people became squeezed between the increasing costs of living and no access to formal employment, more and more children and youth are seen making a living and/or living on the streets. The ‘phenomenon’ of street children has been targeted by many non-governmental organizations (NGOs).
 As NGOs, in the context of economic liberalisation, take the place of governments regarding social services, it is important to understand the nature and quality of NGO assistance. Furthermore, the question of how street children view and experience these services is one that needs to be explored. In this paper I aim to explore these questions in the context of urban Maputo.

description: Hamiltonian systems that are either open, leaking, or contain holes in the phase space possess solutions that eventually escape the system's domain. The motion described by such escape orbits before crossing the escape threshold can be understood as a transient behavior. In this work, we introduce a numerical method to visually illustrate and quantify the transient motion in Hamiltonian systems based on the transient measure, a finite-time version of the natural measure. We apply this method to two physical systems: the single-null divertor tokamak, described by a symplectic map; and the Earth-Moon system, as modeled by the planar circular restricted three-body problem. Our results portray how different locations for the ensemble of initial conditions may lead to different transient dynamical scenarios in both systems. We show that these scenarios can be properly quantified from a geometrical aspect, the transient correlation dimension, and a dynamical aspect, the transient complexity coefficient.

 Diagnosis. The forewing length is 11.0 mm in the male holotype and 12.0 mm in the female paratype. The male of C. himalaya sp. n. is externally distinguished from C. khasia sp. n. by its slightly smaller size, and the narrower forewing with a less distally convex costal margin and a narrower ochreous yellow costal stripe. The male genital capsule of C. himalaya sp. n. differs from C. khasia sp. n. in the larger spinulose bunches of the anellus, the narrower distal section of the valva, the longer setose crest of the ventral plate of the costa, and the longer distal saccular process. The phallus of the new species is somewhat proximally narrower than in C. khasia sp. n. Compared to C. khasia sp. n., the vesica of C. himalaya sp. n. has somewhat shorter and narrower diverticula, and bears a slightly longer and thinner cornutus. The female genitalia of the new species were characterised and diagnosed above under the new genus.
 Distribution. Northeast India (north of West Bengal).
 Etymology. The specific epithet is derived from the Himalaya mountain system and refers to the occurrence of the new species in it. The name is a noon in nominative singular in apposition to the generic name.
