[[male]]. Bulawayo, Rhodesia (Arnold), [[male]]. L.: 12,4 mm. Viel gedrungener, kuerzer und breiter als longinoda. Kiefer matt, am Endrand sehr fein gezaehnelt, breiter und kuerzer als bei longinoda. Der Kopf ist breiter als lang, hinten viel breiter als vorn (bei longinoda ist er laenger als breit); der Hinterrand ist sehr deutlich und schwach konvex (bei longinoda ganz undeutlich und sehr stark konvex). Die Fuehler und die Glieder ueberhaupt sind kuerzer als bei longinoda. Der Thorax ist mindestens so breit als der Kopf, viel breiter als bei longinoda; das Pronotum ist vor allem viel kuerzer, hinten breiter, vorn konvexer und viel mehr unterhalb des Mesonotums liegend. Die Basalflaeche des Epinotums ist im Verhaeltnis viel kuerzer und die abschuessige Flaeche viel hoeher, so lang wie die Basalflaeche und scharf gerandet. Der Knoten ist ganz anders als bei longinoda, viel hoeher und viel kuerzer, kaum laenger als hinten breit, mit einer steilen Vorderflaeche und mit einer schwach konkaven, seitlich gerandeten Hinterflaeche, deren scharfer Rand jedoch oben mit einer fast zahnartigen Erweiterung aufhoert, so dass die Mitte oben nur schwach und undeutlich gerandet ist. Skulptur wie beim [[worker]]; das Pronotum, das Mesonotum und das erste Hinterleibssegment haben eine weitlaeufige grobe Punktierung. Farbe und Behaarung wie beim [[worker]]; die Kiefer und die Tarsen schwarzbraun. Fluegel braun gefaerbt, noch etwas dunkler als bei longinoda.
Das [[male]], das von Emery (Bottego 1896) beschrieben wurde, scheint anders zu sein, aber das vorliegende [[male]] wurde von Herrn Arnold mit den Arbeitern (Nr. 138) gefunden.

description: This work presents the design of an RS(31,27) Reed Solomon encoder for a 3.2 Gbps serial transmitter in 0.18 um CMOS technology. The proposed encoder is designed with a novel full parallel structure optimized for high speed and high stability. One data frame contains 2 interleaved RS(31,27) codes and thus it can correct at most 20 bits of consecutive errors. A corresponding decoder is implemented on Xilinx Kintex-7 FPGA.

description: We present the full tree-order calculation of the process $e^+e^-\to\ell\barν_\ell\; q \bqp$ including the width effects in a way which is consistent with gauge invariance and high energy unitarity and which has a natural interpretation within standard perturbation theory. We also include C- and P-preserving deviations from Standard Model trilinear vector boson couplings. An analysis of the sensitivity of these channels on the trilinear couplings, using well measured angular variables of the four fermion final state, is also presented.

description: The aim of this work is to optimize the design and performance of solar powered γ Stirling engine based on genetic algorithm (GA). A second-order mathematical model which includes thermal losses coupled with genetic algorithm GA has been developed and used to find the best values for different design variables. The physical geometry of the γ Stirling engine has been used as an objective variable in the genetic algorithm GA to determine the optimal parameters. The design geometry of the heat exchanger was considered to be the objective variable. The heater slots height, heater effective length, cooler slots height, cooler effective length, re-generator foil unrolled length and re-generator effective length are assumed to be the objective variables. Also, three different types of working fluids have been used in the model simulation to investigate the effect of the different working fluid on the engine performance. The comparison between the results obtained from the simulation by using the original parameters and the results from the optimized parameters when the engine was powered by solar energy; the higher temperature was 923 K applied to the working fluid when the air, helium, and hydrogen were used as working fluid. The engine power increases from 140.58 watts to 228.54 watts, and it is enhanced by approximately 50%, when the heating temperature is 923 K and the air is used as working fluid. The result showed that the working temperature is one of the most important parameters; because the output power increases by increasing of the hot side temperature.
Describing Analytically the Matter-Enhanced Two-Neutrino Transitions in a Medium

description: A general exact analytic expression for the probability of matter-enhanced two-neutrino transitions in a medium (MSW, RSFP, generated by neutrino FCNC interactions, etc.) is derived. The probability is expressed in terms of three real functions of the parameters of the transitions: the ``jump'' probability and two phases (angles). The results obtained can be utilized, in particular, in the studies of the matter-enhanced transitions/conversions of solar and supernova neutrinos. An interesting similarity between the Schroedinger equation for the radial part of the non-relativistic wave function of the hydrogen atom and the equation governing the MSW transitions of solar neutrinos in the exponentially varying matter density in the Sun is also briefly discussed.

description: We present a framework for the partitioning of a spatial trajectory in a sequence of segments based on spatial density and temporal criteria. The result is a set of temporally separated clusters interleaved by sub-sequences of unclustered points. A major novelty is the proposal of an outlier or noise model based on the distinction between intra-cluster (local noise) and inter-cluster noise (transition): the local noise models the temporary absence from a residence while the transition the definitive departure towards a next residence. We analyze in detail the properties of the model and present a comprehensive solution for the extraction of temporally ordered clusters. The effectiveness of the solution is evaluated first qualitatively and next quantitatively by contrasting the segmentation with ground truth. The ground truth consists of a set of trajectories of labeled points simulating animal movement. Moreover, we show that the approach can streamline the discovery of additional derived patterns, by presenting a novel technique for the analysis of periodic movement. From a methodological perspective, a valuable aspect of this research is that it combines the theoretical investigation with the application and external validation of the segmentation framework. This paves the way to an effective deployment of the solution in broad and challenging fields such as e-science.

We identify the brane configuration which gives $C^3/Z_3$ as a background for the M theory in terms of a Brane Box Model or a (p, q) web model. By taking the orbifold projection on the known spectrum of Kaluza-Klein harmonics of supergravity, we obtain information about the chiral primary operators at the orbifold singularities.

Probing the nature and origin of dust in the reddened quasar IC 4329A with global modelling from X-ray to infrared

description: Cosmic dust is a key tracer of structure formation and evolution in the universe. In active galactic nuclei (AGN) the origin and role of dust are uncertain. Here, we have studied dust in the X-ray bright and reddened type-1 quasar IC 4329A, which exhibits an ionised AGN wind. We incorporated high-resolution X-ray and mid-IR spectroscopy, combined with broad-band continuum modelling, to investigate the properties of dust in this AGN. We used new Chandra HETGS observations taken in June 2017, as well as archival data from XMM-Newton, Swift, HST, Spitzer, IRAS, and Herschel for our IR-optical-UV-X-ray modelling. Two distinct components of dust in IC 4329A are found. One component is in the interstellar medium (ISM) of the host galaxy, and the other is a nuclear component in the AGN torus and its associated wind. The emitting dust in the torus is evident in mid-IR emission (9.7 and 18 micron features), while dust in the wind is present through both reddening and X-ray absorption (O, Si, and Fe edge features). The gas depletion factors into dust for O, Si, and Fe are measured. We derive an intrinsic reddening E(B-V) ~ 1.0, which is most consistent with a grey (flat) extinction law. The AGN wind consists of three ionisation components. From analysis of long-term changes in the wind, we determine limits on the location of the wind components. The two lowest ionisation components are likely carriers of dust from the AGN torus. We find that the dust in the nuclear component of IC 4329A is different from dust in the Milky Way. The dust grains in the AGN torus and wind are likely larger than the standard Galactic dust, and are in a porous composite form (containing amorphous silicate with iron and oxygen). This can be a consequence of grain coagulation in the dense nuclear environment of the AGN.

description: The Ultraviolet Imaging Telescope (UIT) was flown as part of the Astro observatory on the Space Shuttle Columbia in December 1990 and again on the Space Shuttle Endeavor in March 1995. Ultraviolet (1200-3300 Angstroms) images of a variety of astronomical objects, with a 40 arcmin field of view and a resolution of about 3 arcsec, were recorded on photographic film. The data recorded during the first flight are available to the astronomical community through the National Space Science Data Center (NSSDC); the data recorded during the second flight will soon be available as well. This paper discusses in detail the design, operation, data reduction, and calibration of UIT, providing the user of the data with information for understanding and using the data. It also provides guidelines for analyzing other astronomical imagery made with image intensifiers and photographic film.

description: Among the sensory modalities involved in controlling mating behavior in Drosophila melanogaster, contact sex pheromones play a primary role. The key receptor neurons for contact sex pheromones are located on the forelegs, which are activated in males upon touching the female abdomen during tapping events in courtship actions. A fruitless (fru)-positive (fru [+]) male-pheromone sensing cell (M-cell) and a fru [+] female-pheromone sensing cell (F-cell) are paired in a sensory bristle on the legs, and some fru [+] chemoreceptor axons project across the midline in the thoracic neuromere in males but not in females. However, the receptor cells that form sexually dimorphic axon terminals in the thoracic ganglia remain unknown. By generating labeled single-cell clones, we show that only a specific subset of fru [+] chemosensory neurons have axons that cross the midline in males. We further demonstrate that there exist two male-specific bristles, each harboring two chemosensory neurons; neither of which exhibits midline crossing, a masculine characteristic. This study reveals hitherto unrecognized sex differences in chemosensory neurons, imposing us to reinvestigate the pheromone input pathways that impinge on the central courtship circuit.

description: A new monoterpene glycoside named as pedivertoside D (1), together with 13 known compounds (2–14, resp.) were isolated from the whole plant of Pedicularis verticillata L. The new compound was identified as (2E,6E,5R)-5,8-dihydrooxy-2,6-dimethyl-3,7-octadienyl-β-D-glucopyranoside by spectroscopic methods including 2 D-NMR techniques. The known compounds were determined spectroscopically and compared with previously reported spectral data. Compounds 6 and 9 exhibited anticomplementary effects against the classical pathway (CP) with CH50 values of 0.07 mM and 0.23 mM, respectively, which are plausible candidates for developing potent anti-complementary agents from this plant.

description: We study optomechanically induced transparency (OMIT) in a compound system consisting of coupled optical resonators and a mechanical mode, focusing on the unconventional role of loss. We find that optical transparency can emerge at the otherwise strongly absorptive regime in the OMIT spectrum, by using an external nanotip to enhance the optical loss. In particular, loss-induced revival of optical transparency and the associated slow-to-fast light switch can be identified in the vicinity of an exceptional point. These results open up a counterintuitive way to engineer micro-mechanical devices with tunable losses for e.g., coherent optical switch and communications.

description: High-performance p-channel transistors are crucial to implementing efficient complementary circuits in wide-bandgap electronics, but progress on such devices has lagged far behind their powerful electron-based counterparts due to the inherent challenges of manipulating holes in wide-gap semiconductors. Building on recent advances in materials growth, this work sets simultaneous records in both on-current (10 mA/mm) and on-off modulation (four orders) for the GaN/AlN wide-bandgap p-FET structure. A compact analytical pFET model is derived, and the results are benchmarked against the various alternatives in the literature, clarifying the heterostructure trade-offs to enable integrated wide-bandgap CMOS for next-generation compact high-power devices.

description: It is shown that at least four massive neutrinos are needed in order to accommodate the evidences in favor of neutrino oscillations found in solar and atmospheric neutrino experiments and in the LSND experiment. Among all four-neutrino schemes, only two, with a mass spectrum composed of two pairs of neutrinos with close masses separated by the "LSND gap" of the order of 1 eV, are compatible with the results of all neutrino oscillation experiments. In these two schemes the probability of nu_e transitions into other states, the probability of nu_mu->nu_e transitions and the size of CP violation effects in nu_mu->nu_e transitions are suppressed in long-baseline experiments.

description: Using scanning tunneling microscopy, we show that Si deposition on Pt(111) at 300K leads to a network of one-dimensional Si chains. On the bare Pt(111) surface, the chains, embedded into the Pt surface, are orientated along the <112>-direction. They disappear within a few hours in ultrahigh vacuum due to the presence of residual gas. Exposing the chains to different gases deliberately reveals that CO is largely responsible for the disappearance of the chains. The chains can be stabilized by a monolayer of hexagonal boron nitride, which is deposited prior to the Si deposition. The resulting Si chains are rotated by 30° with respect to the chains on the bare Pt(111) surface and survive even an exposure to air for 10 minutes.

description: Consequences of a symmetry, e.g.\ relations amongst Green functions, are renormalization scheme independently expressed in terms of a rigid Ward identity. The corresponding local version yields information on the respective current. In the case of spontaneous breakdown one has to define the theory via the BRS invariance and thus to construct rigid and current Ward identity non-trivially in accordance with it. We performed this construction to all orders of perturbation theory in the abelian Higgs model as a prelude to the standard model. A technical tool of interest in itself is the use of a doublet of external scalar ``background'' fields. The Callan-Symanzik equation has an interesting form and follows easily once the rigid invariance is established.

Nebular Abundance Errors

description: The errors inherent to the use of the standard "ionization correction factor" ("i_CF") method of calculating nebular conditions and relative abundances of H, He, N, O, Ne, S, and Ar in emission line nebulae have been investigated under conditions typical for planetary nebulae. The photoionization code CLOUDY was used to construct a series of model nebulae with properties spanning the range typical of PNe. Its radial "profiles" of bright, frequently observed optical emission lines were then summed over a variety of "apertures" to generate sets of emission line measurements. These resulting line ratios were processed using the i_CF method to "derive" nebular conditions and abundances. We find that for lines which are summed over the entire nebula the i_CF-derived abundances differ from the input abundances by less than 5% for He and O up to 25% or more for Ne, S, and Ar. For resolved observations, however, the discrepancies are often much larger and are systematically variable with radius. This effect is especially pronounced in low-ionization zones where nitrogen and oxygen are neutral or once-ionized such as in FLIERs, ansae and ionization fronts. We argue that the reports of stellar-enriched N in the FLIERs of several PNe are probably specious.

description: The synthesis of thin films of magnetic topological materials is necessary to achieve novel quantized Hall effects and electrodynamic responses. EuIn2As2 is a recently predicted topological axion insulator that has an antiferromagnetic ground state and an inverted band structure, but that has only been synthesized and studied as a single crystal. We report on the synthesis of c-axis oriented EuIn2As2 films on sapphire substrates by molecular beam epitaxy. By carefully tuning the substrate temperature during growth, we stabilize the Zintl phase of EuIn2As2 expected to be topologically non-trivial. The magnetic properties of these films reproduce those seen in single crystals, but their resistivity is enhanced when grown at lower temperatures. We additionally find that the magnetoresistance of EuIn2As2 is negative even up to fields as high as 31T. while it is highly anisotropic at low fields, it becomes nearly isotropic at high magnetic fields above 5T. Overall, the transport characteristics of EuIn2As2 appear similar to those of chalcogenide topological insulators, motivating the development of devices to gate tune the Fermi energy and reveal topological features in quantum transport.

description: We study the unitary supermultiplets of the N=8, d=5 anti-de Sitter (AdS) superalgebra SU(2,2|4) which is the symmetry algebra of the IIB string theory on AdS_5 X S^5. We give a complete classification of the doubleton supermultiplets of SU(2,2|4) which do not have a Poincare limit and correspond to d=4 conformal field theories (CFT) living on the boundary of AdS_5. The CPT self-conjugate irreducible doubleton supermultiplet corresponds to d=4, N = 4 super Yang-Mills theory. The other irreducible doubleton supermultiplets come in CPT conjugate pairs. The maximum spin range of the general doubleton supermultiplets is 2. In particular, there exists a CPT conjugate pair of doubleton supermultiplets corresponding to the fields of N=4 conformal supergravity in d=4 which can be coupled to N=4 super Yang-Mills theory in d=4. We also study the "massless" supermultiplets of SU(2,2|4) which can be obtained by tensoring two doubleton supermultiplets. The CPT self-conjugate "massless" supermultiplet is the N=8 graviton supermultiplet in AdS_5. The other "massless" supermultiplets generally come in conjugate pairs and can have maximum spin range of 4. We discuss the implications of our results for the conjectured CFT/AdS dualities.

description: The temporal evolution of entanglement between a noisy system and an ancillary system is analyzed in the context of continuous time open quantum system dynamics. Focusing on a couple of analytically solvable models for qubit systems, we study how Markovian and non-Markovian characteristics influence the problem, discussing in particular their associated entanglement-breaking regimes. These performances are compared with those one could achieve when the environment of the system is forced to return to its input configuration via periodic instantaneous resetting procedures.

description: Background: Extracorporeal Membrane Oxygenation (ECMO) is now a standard life-support modality in intensive care, particularly for emergency situations of cardiac and respiratory failure. Initially applied only in controlled intensive care settings, its application has now extended to pre-hospital, intraoperative, and emergency settings, transforming the treatment of life-threatening conditions.

Objective: This review analyzes the evolving role of ECMO in emergency medical care, encompassing its indications, utilization in various clinical situations, and impact on patient outcome.

Methods: A narrative review was conducted through the examination of peer-reviewed articles, case reports, and clinical guidelines on ECMO utilization in the emergency department. Databases included PubMed, Scopus, and ScienceDirect databases with emphasis on publication in the last decade.

Results: ECMO has demonstrated significant benefits in numerous emergency conditions, including cardiac arrest (E-CPR), pulmonary embolism, trauma-induced ARDS, and cardiogenic shock. Enhanced survival and neurological outcomes have been reported with early initiation and correct patient selection for ECMO. Greater accessibility and outcomes have also been achieved with the use of mobile ECMO teams and pre-hospital cannulation.

Conclusion: ECMO is no longer the preserve of routine ICU management but becomes a lifeline in urgent treatment of seriously ill patients. Its success depends greatly, though, on prompt initiation, specialist multidisciplinary teams, and availability of infrastructure. Standard emergency ECMO guidelines and its reach through mobile platforms and training are suggestions for the future.

description: The relation between the gauge-invariant local BRST cohomology involving the antifields and the gauge-fixed BRST cohomology is clarified. It is shown in particular that the cocycle conditions become equivalent once it is imposed, on the gauge-fixed side, that the BRST cocycles should yield deformations that preserve the nilpotency of the (gauge-fixed) BRST differential. This shows that the restrictions imposed on local counterterms by the Quantum Noether condition in the Epstein--Glaser construction of gauge theories are equivalent to the restrictions imposed by BRST invariance on local counterterms in the standard Lagrangian approach.

description: The cloud computing society where everyone can access the Internet using various information tools has been already developed all over the world, and it is the times of IoT and IoE when various things were connected to the Internet. Additionally, as the digital infrastructures are toughened in the effective measures for disaster prevention and reduction around the worlds, the importance of ICT and internet environment is widely recognized especially in recent Japan. The present study aims to describe the utilization and issues of utilization of social media at the Time of Heavy-rain disaster in southern Kyushu, Japan in 2020. At the time of torrential rain in southern Kyusyu in 2020, social media is utilized powerful tools to submit and gather the information related to the disaster by the general public in addition to the central local governments. However, it is not possible for local governments to utilize social media for many reasons such as human resources and information literacy of the staffs. Based on the real cases during disasters, it is desirable that each local government should promote the setting of rules for utilizing Twitter in particular, according to the local situations beforehand.

description: The sustainability of the seriously threatened African miombo woodlands depends on their capability to maintain sufficient natural regeneration. This study focused on the regeneration dynamics and the impacts of silvicultural treatments of fencing, site preparation, and thinning in the Kitulangalo forest reserve in Tanzania. Mixed models were applied to analyze the change in number of stems during the nine-years observation period on a set of permanent experimental plots. There was a significant decrease in the total number of stems (from 29 800 ha−1 to 19 100 ha−1) but a significant increase in the number of main stems (from 9 300 ha−1 to 11 100 ha−1) during observation period. The proportion of empty regeneration plots (zero seedlings and saplings on a regeneration plot of 4 m2) was initially very low (7.3%) and decreased further during the study period to 5.3%. Greater stand density was associated with lower density of regeneration. Fencing implied a greater increase in the number of main stems but a sharper drop in the total number of stems by reducing animal disturbances. The findings indicate that the forests at Kitulangalo are recovering from past abuse and likely developing toward more sustainable stand structures and sustainability.
