description: In crossover design experiments, the proportional model, where the carryover effects are proportional to their direct treatment effects, has draw attentions in recent years. We discover that the universally optimal design under the traditional model is E-optimal design under the proportional model. Moreover, we establish equivalence theorems of Kiefer-Wolfowitz's type for four popular optimality criteria, namely A, D, E and T (trace).

description: Future vehicular networks in the emerging era of 5G will be characterized by ubiquitous connectivity across heterogeneous networks (HetNets) while maintaining their required Quality of Service (QoS). Visible light communication (VLC) and mmWave are both promising candidates for use in last mile communication networks. However, selection of appropriate technology for vehicular systems is dependent on their performance in outdoor networks. Due to cell densification inherent in 5G communication networks, selection of an appropriate micro-mobility scheme that ensures seamless connectivity with QoS provision is critical. This thesis focuses on the investigation of these issues. VLC and mmWave are both evaluated for outdoor vehicular networks based on their propagation characteristics and attenuation due to adverse weather conditions. Based on comparative design analysis, we proposed the adoption of a dual-link, multi beam VVLC system for outdoor infrastructure vehicular communication networks. The design analysis was carried out using existing empirical and mathematical models. Compared to mmWave system, the proposed model was found a safer, power efficient and economically more viable solution. Multiprotocol Label Switching (MPLS) based micro-mobility management has the advantage of fast and efficient packet forwarding. This thesis proposes a hierarchical IntServ based MPLS architecture to overcome the limitations found in existing MPLS based micro-mobility schemes in terms of latency and explicit QoS support necessary for 5G vehicular communication networks. The survivability of communication networks is another critical issue. This thesis also proposes an improved fast re-routing scheme that decreases the path restoration delay compared to existing solutions proposed by IETF and found in the open literature. Our proposed schemes are evaluated through both mathematical and simulative analysis. The models were developed and simulated using the OPNET simulator to validate the analytical results. The results were also compared with other existing schemes to demonstrate the performance benefits of the proposed schemes.

description: Hyperactivation of extracellular signal-regulated kinase 1 and 2 (ERK1/2) by dopamine D₁ receptor (D₁R) in the striatum is a characteristic feature of several neuropsychiatric conditions, including drug addiction and L-3,4-dihydroxyphenylalanine (L-DOPA)-induced dyskinesia (LID) within individuals suffering from Parkinson’s disease. However, the current mechanistic gap in understanding of D₁R-mediated regulation of ERK1/2, both in physiology and disease, hampers effective treatment of these conditions. One important factor that is underexplored in this regard is the role played by proteins that physically interact with the intracellular regions of D₁R. Using yeast two-hybrid screens and co-transfected human embryonic kidney 293 (HEK293) cells, our laboratory has recently characterized an interaction between the third intracellular loop of D₁R and synapse-associated protein 102 (SAP102), a member of the membrane-associated guanylate kinase family. Moreover, our lab identified endogenous D₁R-SAP102 complex within rat striatum and hippocampus. Interestingly, SAP102 regulates ERK signaling pathway within the hippocampus, and modulates adenosine A2A receptor-mediated ERK1/2 activation within transfected HEK293 cells. Capitalizing on the above findings, I hypothesized a role for SAP102 in controlling D₁R-mediated ERK1/2 activation. Herein, I demonstrate using co-transfected HEK293 cells that SAP102 alters the temporal activation of ERK1/2 by D₁R. Intriguingly, experiments using the protein kinase A (PKA) inhibitors H89 and protein kinase inhibitor 14-22 amide myristoylated show that SAP102 also facilitates a switch in D₁R-mediated ERK1/2 activation from a PKA-independent to PKA-dependent pathway. Furthermore, SAP102 reduces basal ERK1/2 activation in HEK293 cells, reminiscent of a previously documented role of hippocampal SAP102. To the best of my knowledge, my findings are the first to demonstrate scaffolding protein-mediated switching of a G protein-coupled receptor (GPCR) signaling pathway. Future studies aimed at uncovering the details of this process should provide valuable insight on the mechanisms contributing to D₁R-mediated ERK1/2 activation, and may also offer clues to the existence of similar phenomena for other GPCRs. These studies would also aid development of improved pharmacological treatment options for conditions with dysfunctional D₁R-dependent ERK1/2 activation.

description: W ciągu ponad dwudziestu lat istnienia federacji władzom Etiopii udało się zachować jedność państwa mimo istnienia ugrupowań separatystycznych, które działają głównie tam, gdzie grupa etniczna rozdzielona jest pomiędzy Etiopię a sąsiednie państwa. Przypadkiem szczególnym jest nacjonalizm Oromo, doskonale zorganizowany i oparty na solidnych podstawach intelektualnych. Inne ruchy separatystyczne stanowią raczej wyraz konfliktów z władzą centralną o wykorzystanie zasobów naturalnych, bądź są kontynuacją procesów mających swoje korzenie w czasach kształtowania się obecnych granic Etiopii. Nie sposób ich uznać za dobrze ukształtowane projekty polityczne, które w przewidywalnej przeszłości mogłyby doprowadzić do powstania nowych państw w Rogu Afryki.

description: Optical quantum information processing exploits interference of quantum light. However, when the interferometer is composed of optical fibers, degradation of interference visibility due to the finite polarization extinction ratio becomes a problem. Here we propose a method to optimize interference visibility by controlling the polarizations to a crosspoint of two circular trajectories on the Poincaré sphere. Our method maximizes visibility with low optical loss, which is essential for quantum light, by using fiber stretchers as polarization controllers. We also experimentally demonstrate our method, where the visibility was maintained basically above 99.9% for three hours using fiber stretchers with an optical loss of 0.02 dB (0.5%). Our method makes fiber systems promising for practical fault-tolerant optical quantum computers.

description: Web archiving encompasses several challenges that we face in the midst of the radical changes that are the focus of the ACRL-NY 2013 Symposium. Like many other interdisciplinary, wide-ranging and highly networked fields, human rights scholarship relies extensively on web-based information, but much of this content is at risk of disappearing within a relatively short time. To meet the needs of the scholarly community, the Human Rights Web Archive @ Columbia University (HRWA) was created. The HRWA (http://hrwa.cul.columbia.edu/) is a searchable collection of archived copies of human rights websites created by non-governmental organizations, national human rights institutions, tribunals and individuals. In this poster we will detail our early progress in the assessment of the effectiveness of the HRWA through user testing and a review of scholarly publishing in journals focusing on human rights research. We will also discuss how keeping users actively engaged is at the core of our evolving collecting policy for web archives. In sharing our experiences with a collection development policy centered in an active and agile feedback loop, we hope to shed light on strengths and opportunities for growth including via collaborative initiatives.

Libraries--Special collections

description: To promote scholarly research on the unique collections at Columbia University’s C.V. Starr East Asian Library, we worked closely with faculty members to initiate several symposia in 2011-2012. These symposia enabled us to promote our unique collections while building a global community of scholars who would benefit from the research on these special materials. The library employs innovative discovery methods for outreach that include hosting symposia, digitizing the remarks and presentations at these events, utilizing Columbia’s YouTube channel, and creating related websites and blogs. In this panel, Director Jim Cheng gave an overview of the vision and plan of our approach at the Starr Library. Beth Katzoff, Archivist and Public Services Librarian, discussed the case of the Makino Mamoru Collection on the History of East Asian Film (Makino Collection)*, its symposium in 2011, and the various tools she uses to promote this unique collection. These include the creation of the online finding aid (in process), the symposium webpage with links to the related digital lectures, the Makino Collection blog, and plans for future digital projects. Our next steps include facing the challenges of meeting various user needs and addressing copyright clearance issues. The focus of this talk is not to discuss digitizing items in the Makino Collection, but rather how to process and provide the means of discovery for the library’s archival materials. The Makino Symposium and its digitized presentations are the first in a series that will form a digital library of research on and online access to the unique archival materials at Starr Library. *The Makino Collection archive (over 900 linear feet) was purchased by Columbia University in 2006, processing began in September 2008, and continues today. The collection focuses on print materials mostly related to Japanese film that were collected over the course of fifty years by former documentary filmmaker and film researcher, Makino Mamoru.

Precision of Positional Information Along the Developing Cochlea Radial Axis: Linear BMP Activity Helps Set the Stage

description: Developing embryos rely on morphogenetic signals to inform cells about where they are in space and respond to their positions through the appropriate expression of fate-determining genes. Computational and theoretical analyses are powerful tools that have proven to enhance and inform experimental work in developmental biology. In the study of positional information, mechanistic ordinary and partial differential equations are able to test and suggest hypotheses for morphogen network evolution. Information theoretic interpretations of these profiles have also been proven to be valuable towards making predictions. These approaches are reviewed and used here together to investigate the morphogenetic signals instructing pattern formation during the earliest phase of development in the cochlea. When the transcription factors SOX2 and pSMAD1/5/9 (two crucial carriers of positional information)
 are quantified here for the first time, new observations, questions, and hypotheses emerge that have been out of reach otherwise. Perhaps most intriguingly is the identification of a linear pSMAD1/5/9 profile over a supermajority of the radial axis. This linear profile is shown to ‘set the stage’ by creating a 1:1 map between position and signal concentration. Feasible mechanisms responsible for maintaining this profile are simulated to propose the existence of a yet-unidentified BMP sink on the medial edge and suggests a role for Follistatin interaction with BMP, which there are currently doubts around. This likewise sets thestage for new experimental and simulation work to home in on the network dynamics implemented by the cochlea to turn a diffusive morphogen system into a linear signal. While BMP sets the stage of the radial axis, adding SOX2 more precisely assigns cells their places for this opening act with its steep profile that reduces positional error. The transition into subsequent phases where cell fates are assigned relies dependently on the precision encoded in this first phase in order to create the cellular pattern required to enable the sense of hearing.

description: The multiferroic manganese tungstate (MnWO4) has been studied by high-pressure Raman spectroscopy at room temperature under quasi-hydrostatic conditions up to 39.3 GPa. The low-pressure wolframite phase undergoes a phase transition at 25.7 GPa, a pressure around 8 GPa higher than that found in previous works which used less hydrostatic pressure-transmitting media. The pressure dependence of the Raman active modes of both the low- and high-pressure phases are reported and discussed comparing with the results available in the literature for MnWO4 and related wolframites. A gradual pressure-induced phase transition from the low- to the high- pressure phase is suggested on the basis of the linear intensity decrease of the Raman mode with the lowest frequency up to the end of the phase transition.

description: The hot gas that constitutes the intracluster medium (ICM) has been studied at X-ray and millimeter/sub-millimeter wavelengths (Sunyaev-Zeldovich effect) for decades. Fast radio bursts (FRBs) offer an additional method of directly measuring the ICM and gas surrounding clusters, via observables such as dispersion measure (DM) and Faraday rotation measure (RM). We report the discovery of two FRB sources detected with the Deep Synoptic Array (DSA-110) whose host galaxies belong to massive galaxy clusters. In both cases, the FRBs exhibit excess extragalactic DM, some of which likely originates in the ICM of their respective clusters. FRB 20220914A resides in the galaxy cluster Abell 2310 at z=0.1125 with a projected offset from the cluster center of 520 kpc. The host of a second source, FRB 20220509G, is an elliptical galaxy at z=0.0894 that belongs to the galaxy cluster Abell 2311 at projected offset of 870 kpc. These sources represent the first time an FRB has been localized to a galaxy cluster. We combine our FRB data with archival X-ray, SZ, and optical observations of these clusters in order to infer properties of the ICM, including a measurement of gas temperature from DM and ySZ of 0.8-3.9 keV. We then compare our results to massive cluster halos from the IllustrisTNG simulation. Finally, we describe how large samples of localized FRBs from future surveys will constrain the ICM, particularly beyond the virial radius of clusters.

description: High-dimensional data sets are commonly collected in many contemporary applications arising in various fields of scientific research. We present two views of finite samples in high dimensions: a probabilistic one and a nonprobabilistic one. With the probabilistic view, we establish the concentration property and robust spark bound for large random design matrix generated from elliptical distributions, with the former related to the sure screening property and the latter related to sparse model identifiability. An interesting concentration phenomenon in high dimensions is revealed. With the nonprobabilistic view, we derive general bounds on dimensionality with some distance constraint on sparse models. These results provide new insights into the impacts of high dimensionality in finite samples.

description: We study a phenomenological model where the lightest dark matter (DM) particles are the pseudo-Goldstone excitations associated with a spontaneously broken symmetry, and transforming linearly with respect to an unbroken group H. For definiteness we take H = SU(N) and assume the Goldstone particles are bosons; in parallel with QCD, we refer to these particles as dark-matter pions. This scenario is in contrast to the common assumption that DM fields transform linearly under the full symmetry of the model. We illustrate the formalism by treating in detail the case of H = SU(2), in particular we calculate all the interactions relevant for the Boltzmann equations, which we solve numerically; we also derive approximate analytic solutions and show their consistency with the numerical results. We then compare the results with the constraints derived from the cold DM and direct detection experiments and derive the corresponding restrictions on the model parameters.

description: The mass-loss mechanisms in M-type AGB stars are not well understood, in particular, the formation of dust-driven winds from the innermost gaseous layers around these stars. One way to understand the gas-dust interaction in these regions and its impact on the mass-loss mechanisms is through the analysis of high-resolution observations of the stellar surface and its closest environment. We aim at characterizing the inner circumstellar environment (~3 R*) of the M-type Mira star R Car in the near-infrared at different phases of a pulsation period. We used GRAVITY interferometric observations in the K-band obtained at two different epochs over 2018. Those data were analyzed using parametric models and image reconstruction of both the pseudo-continuum and the CO band-heads observed. The reported data are the highest angular resolution observations on the source in the K-band. We determine sizes of R Car's stellar disk of 16.67 +- 0.05 mas (3.03 au) in January 2018 and 14.84+-0.06 mas (2.70 au) in February 2018, respectively. From our physical model, we determined temperatures and size ranges for the innermost CO layer detected around R Car. We find that magnesium composites, Mg2SiO4 and MgSiO3, have temperatures and condensation distances consistent with the ones obtained for the CO layer model and pure-line reconstructed images, being them the most plausible dust types responsible of wind formation. Our reconstructed images show evidence of asymmetrical and inhomogeneous structures, which might trace a complex and perhaps clumpy structure of the CO molecule distribution. Our work demonstrates that the conditions for dust nucleation and thus for initialising dust-driven winds in M-type AGB stars are met in R Car and we identify Magnesium composites as the most probable candidates. This observational evidence is crucial to constrain the role of convection and pulsation in M-type stars.

description: In this study, the flame retardant effect of the Zn salt of 10-hydroxy-9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (Zn-DOPOx), melamine polyphosphate (MPP) and their mixture was investigated towards the mode of action in glass fiber-reinforced polyamide 66 (PA 66 GF). The flammability was evaluated using UL 94 V and cone calorimetry. Influence on char formation was analyzed by SEM. Thermal decomposition of Zn-DOPOx and MPP was studied by TGA and ATR-FTIR. The release of gaseous PA 66 decomposition products was investigated using TGA-DTA-FTIR. Combining Zn-DOPOx and MPP leads to an improvement in flame retardancy, most pronounced for equal parts of weight. Mode of action changes significantly for Zn-DOPOx:MPP (1:1) compared to the sole components and a strong interaction between Zn-DOPOx and MPP is revealed, resulting in a more open char structure. Fuel dilution as well as less exothermic decomposition are essential for the mode of action of the combination. Through low HRR values and high CO/CO₂ ratio during cone calorimetry measurements, a significant increase in gas phase activity was proven. Therefore, it is concluded that Zn-DOPOx:MPP (1:1) leads to a significant increase in flame retardancy through a combination of mode of actions in the gas and condensed phase resulting from the change in thermal stability.

description: We use atomistic-based simulations to investigate the behavior of ferromagnetic skyrmions being continuously compressed against a rigid wall under dc and ac drives. The compressed skyrmions can be annihilated close to the wall and form a conformal crystal with both a size and a density gradient, making it distinct from conformal crystals observed previously for superconducting vortices and colloidal particles. For both dc and ac driving, the skyrmions can move transverse to the compression direction due to a combination of density and size gradients. Forces in the compression direction are converted by the Magnus force into transverse motion. Under ac driving, the amount of skyrmion annihilation is reduced and we find a skyrmion Magnus ratchet pump. We also observe shear banding in which skyrmions near the wall move up to twice as fast as skyrmions further from the wall. When we vary the magnitude of the applied drive, we find a critical current above which the skyrmions are completely annihilated during a time scale that depends on the magnitude of the drive. By varying the magnetic parameters, we find that the transverse motion is strongly dependent on the skyrmion size. Smaller skyrmions are more rigid, which interferes with the size gradient and destroys the transverse motion. We also confirm the role of the size gradient by comparing our atomistic simulations with a particle-based model, where we find that the transverse motion is only transient. Our results are relevant for applications where skyrmions encounter repulsive magnetic walls, domain walls, or interfaces.

description: We report the thermodynamic properties of Bose and Fermi ideal gases immersed in periodic structures such as penetrable multilayers or multitubes simulated by one (planes) or two perpendicular (tubes) external Dirac comb potentials, while the particles are allowed to move freely in the remaining directions. Although the bosonic chemical potential is a constant for $T < T_c$, a non decreasing with temperature anomalous behavior of the fermionic chemical potential is confirmed and monitored as the tube bundle goes from 2D to 1D when the wall impenetrability overcomes a critical value. In the specific heat curves dimensional crossovers are very noticeable at high temperatures for both gases, where the system behavior goes from 3D to 2D and latter to 1D as the wall impenetrability is increased.

description: Rapid, irreversible changes of magnetic topology and sunspot structure associated with flares have been systematically observed in recent years. The most striking features include the increase of horizontal field at the polarity inversion line (PIL) and the co-spatial penumbral darkening. A likely explanation of the above phenomenon is the back reaction to the coronal restructuring after eruptions: a coronal mass ejection carries the upward momentum while the downward momentum compresses the field lines near the PIL. Previous studies could only use low resolution (above 1") magnetograms and white-light images. Therefore, the changes are mostly observed for X-class flares. Taking advantage of the 0.1" spatial resolution and 15s temporal cadence of the New Solar Telescope at Big Bear Solar Observatory, we report in detail the rapid formation of sunspot penumbra at the PIL associated with the C7.4 flare on 2012 July 2. It is unambiguously shown that the solar granulation pattern evolves to alternating dark and bright fibril structure, the typical pattern of penumbra. Interestingly, the appearance of such a penumbra creates a new delta sunspot. The penumbral formation is also accompanied by the enhancement of horizontal field observed using vector magnetograms from the Helioseismic and Magnetic Imager. We explain our observations as due to the eruption of a flux rope following magnetic cancellation at the PIL. Subsequently the re-closed arcade fields are pushed down towards the surface to form the new penumbra. NLFFF extrapolation clearly shows both the flux rope close to the surface and the overlying fields.

The muon charge asymmetry is presented in two kinematic regions in muon transverse momentum and event missing transverse energy: (p^μ_{T} > 25 GeV, \met > 25 GeV) and (p^μ_{T} > 35 GeV, \met > 35 GeV). The measured asymmetries are compared with theory predictions made using three parton distribution function sets. The predictions do not describe the data well for p^μ_{T} > 35 GeV, \met > 35 GeV, and larger values of muon pseudorapidity.

description: Masicera ambulans Rondani, 1861
ORIGINAL DESCRIPTION: 1861e: 19 (key), 29 (description).
TYPE LOCALITY: “ in collibus ditionis parmensis [Parmese hills (Italy)]”.
TYPE MATERIAL: 2 ♂♂, syntypes (one missing right hind-leg) (MZUF: Box 15): Masicera Macq. / ambulans Rnd. / 756; 1 ♂, syntype (missing right fore- and mid-legs) (OUMNH General Collection: Box 167.7): syntype / Type / M. ambulans Ex. Coll. Big. / Xylotachina diluta (Meigen, 1824) det. Herting / M. ambulans ♂ Italia, Rond. / Verrall-Collin Palaearctic coll. Ox. Uni. Mus. Nat. Hist. (OUMNH) OUMNH –1967–018 / Tachinidae Xylotachina diluta (Meigen, 1824), Palaearctic.
CURRENT STATUS: junior synonym of Xylotachina diluta (Meigen, 1824) (Herting & Dely-Draskovits 1993: 222).
REMARKS: Rondani (1861e: 29) described Masicera ambulans from just the male sex, without specifying the exact number of specimens, but giving a single measurement of length, despite there being three specimens in the type series found in this study: “ Marem tantum legi [I collected the male only]”, treating it within the subgenus Ceromasia Rondani, 1856, which is now considered as a valid genus (O’Hara et al. 2011: 50). We consider the three specimens as syntypes. An additional six specimens in the MZUF numbered “756” are not included in the MZUF type series because their labels are yellowish rather than the greenish color of Rondani’s original handwritten ones and are in a lower row in the Box, for which reason we treat them to be subsequent additions.

description: Here we report on a light triggered remote control of microgel size in the presence of photosensitive surfactant. The hydrophobic tail of the cationic surfactant contains azobenzene group that undergoes a reversible photo-isomerization reaction from a trans- to a cis-state accompanied by a change in the hydrophobicity of the surfactant. We have investigated light assisted behaviour and the complex formation of the microgels with azobenzene containing surfactant over the broad concentrational range starting far below and exceeding several times of the critical micelle concentration (CMC). At small surfactant concentration in solution (far below CMC), the surfactant in the trans-state accommodates within the microgel causing its compaction, while the cis-isomer desorbs out of microgel resulting in its swelling. The process of the microgel size change can be described as swelling on UV irradiation (trans-cis isomerization) and shrinking on irradiation with blue light (cis-trans isomerization). However, at the surfactant concentrations larger than CMC, the opposite behaviour is observed: the microgel swells on blue irradiation and shrinks during exposure to UV light. We explain this behaviour theoretically taking into account isomer dependent micellization of surfactant within the microgels.

description: The Interstellar Boundary Explorer (IBEX) images the heliosphere by observing energetic neutral atoms (ENAs). The IBEX-Hi instrument onboard IBEX provides full-sky maps of ENA fluxes produced in the heliosphere and very local interstellar medium (VLISM) through charge exchange of suprathermal ions with interstellar neutral atoms. The first IBEX-Hi results showed that in addition to the anticipated globally distributed flux (GDF), a narrow and bright emission from a circular region in the sky, dubbed the IBEX ribbon, is visible in all energy steps. While the GDF is mainly produced in the inner heliosheath, ample evidence indicates that the ribbon forms outside the heliopause in the regions where the interstellar magnetic field is perpendicular to the lines of sight. The IBEX maps produced by the mission team distribute the observations into $6°\times6°$ rectangle pixels in ecliptic coordinates. The overlap of the GDF and ribbon components complicates qualitative analyses of each source. Here, we find the spherical harmonic representation of the IBEX maps, separating the GDF and ribbon components. This representation describes the ENA flux components in the sky without relying on any pixelization scheme. Using this separation, we discuss the temporal evolution of each component over the solar cycle. We find that the GDF is characterized by larger spatial scale structures than the ribbon. However, we identify two isolated, small-scale signals in the GDF region that require further study.

ORIGINAL DESCRIPTION: 1861e: 19 (key), 30 (description).
TYPE LOCALITY: “ in agro parmensi [Parmese territory (Italy)]”.
TYPE MATERIAL: not found in this study.
CURRENT STATUS: junior synonym of Buquetia musca Robineau-Desvoidy, 1847 (Herting & Dely-Draskovits 1993: 192, O’Hara et al. 2020: 297).
REMARKS: Rondani (1861e: 30) described both sexes of Masicera setifacies without specifying the exact number of specimens and not giving a range of lengths, treating it within the subgenus Ceromasia Rondani, 1856, which is now considered as a valid genus (O’Hara et al. 2011: 50). We were unable to locate any type material of this nominal species in our study.

Petagnia occlusa

description: Petagnia occlusa Rondani, 1856
ORIGINAL DESCRIPTION: 1856: 61.
TYPE LOCALITY: Rondani gave no type locality in his original description but presumably it is Italy because the work deals with Italian species.
TYPE MATERIAL: 1 ♂, syntype (very dirty, covered with mold, missing left wing and all legs) (MZUF: Box 9): Petagna [sic!] Rdn. / subpetiolata Rnd. / 458; 1 ♀, syntype (OUMNH General Collection: Box 166.10): syntype / Type / P. subpetiolata Ex. Coll. Big. / Verrall-Collin Palaearctic coll. Ox. Uni. Mus. Nat. Hist. (OUMNH) OUMNH –1967–018 / Tachinidae Tachininae Petagnia subpetiolata Rondani, 1859, Palaearctic.
CURRENT STATUS: nomen nudum (Herting & Dely-Draskovits 1993: 293); valid species (O’Hara et al. 2011: 140, 2020: 771) (also see Remarks).
REMARKS: Rondani’s (1856: 61) key for the genus Petagnia Rondani 1856 lists Petagnia occlusa as its type species, but he did not provide a detailed description, type locality, number or sex of the specimens. Rondani (1859b: 24) without any explanation, proposed the substitute name Petagnia subpetiolata for Petagnia occlusa, the type species of the genus described in Rondani (1856). Schiner (1861b: 527), Braun & Bergenstamm (1889: 129), Bezzi & Stein (1907: 402), Herting (1969: 201), Mesnil (1973: 1167), Herting & Dely-Draskovits (1993: 293), Pape et al. (1995: 25); Cerretti (2010: 325) considered Petagnia occlusa as a nomen nudum and Petagnia subpetiolata as a valid species. Sabrosky (1999: 239) considered Petagnia occlusa as the valid name and Petagnia subpetiolata as a substitute name. O’Hara et al. (2011: 140) considered both Petagnia occlusa and Petagnia subpetiolata as available names. We consider all the nominal type species proposed in Rondani (1856) as available because he always provided elements for their identification, therefore Petagnia subpetiolata is an unjustified substitute name and a junior synonym of Petagnia occlusa. Even if Petagnia subpetiolata has been usually used as the valid name and Petagnia occlusa as a nomen nudum, Article 23.9.1 (I.C.Z.N 1999) cannot be applied since at least Sabrosky (1999: 239) considered Petagnia occlusa as a valid name. We found two syntypes in this study.

description: Stratiomys sericeiventris Rondani, 1848
ORIGINAL DESCRIPTION: 1848b: 102.
TYPE LOCALITY: “ Brasile [Brazil]” (Rondani 1848b: 63); [Belem (Pará), Brazil] (Papavero 1973: 343). See Remarks.
TYPE MATERIAL: 1 specimen, syntype (sex not determinable, dirty, covered with mold) (MZUN: Box Coll. entomol. extra-europea, Fam. Stratiomidei - Gen. Philocera a Psellidotus): Stratiomys sericeiventris Rnd., Brasile / M. Zool. N° 10967; 1 ♀, syntype (missing right wing) (MZUN: Box Coll. entomol. extra-europea, Fam. Stratiomidei - Gen. Philocera a Psellidotus): ♀.
CURRENT STATUS: junior synonym of Hoplitimyia mutabilis (Fabricius, 1787) (James 1973: 42, Woodley 2001: 266).
REMARKS: Rondani (1848b: 102) described Stratiomys sericeiventris from just the male sex, without specifying the exact number of specimens, but giving a single measurement of length, despite there being two specimens in the type series found in this study, from material collected in South America by V. Ghiliani. Costa (1864: 87, 1866: 38) listed two MZUN specimens, one numbered “2601” and one “880”. We also found two syntypes in this study. Although Rondani (1848b: 63) only gave the type locality as “ Brasile ”, Papavero (1973: 343) gave a more accurate type locality based on a note in Spinola (1853) that said all specimens collected by Ghiliani in 1846 were collected in Belem, Pará, Brazil.

description: The modified Lane-Emden equation for stellar hydrostatic equilibrium in f(R)-gravity is numerically solved by using an iterative procedure. Such an integro-differential equation can be obtained in the weak field limit approximation of f(R)-gravity by considering a suitable polytropic equation of state in the modified Poisson equation. The approach allows, in principle, to deal with still unexplored self-graviting systems that could account for exotic stellar structures that escape standard stellar theory.
