Males: Dorsal setae much shorter and borne on weak tubercles, legs I and IV very long, more than twice length of body but legs II and III of ordinary length i.e. as long as the body. Aedeagus slightly curved, narrowing caudally to tip.
Leg chaetotaxy: tarsi 13(2)-10(1)-9-8; tibiae 9-7-8-7; genua 4-4-3-2; femora 5-4-3-3; coxae 2-2-1-1.
 Specimen examined: 8 females and 5 males collected on Oxalis compressa (Oxalidaceae) from Runda, Kiambu district (S01º13.470'; 036º48.050').
 Remarks: This species has a worldwide distribution and has been reported from a wide range of hosts. Many weed species of the genus Oxalis have been recorded to host this species. From Africa, the earlier reports of this species are from Egypt, Southern Africa and the Indian Ocean islands of Madagascar and Mauritius. In the field, the damage symptoms of this species are visible as silver stipples on the leaves of the host. They prefer the under side of the leaves as is typical for most spider mites. They are bright red and their long legs and setae are conspicuous even under a hand lens.

description: Attempts of studying implicit regularization associated to gradient descent (GD) have identified matrix completion as a suitable test-bed. Late findings suggest that this phenomenon cannot be phrased as a minimization-norm problem, implying that a paradigm shift is required and that dynamics has to be taken into account. In the present work we address the more general setup of tensor completion by leveraging two popularized tensor factorization, namely Tucker and TensorTrain (TT). We track relevant quantities such as tensor nuclear norm, effective rank, generalized singular values and we introduce deep Tucker and TT unconstrained factorization to deal with the completion task. Experiments on both synthetic and real data show that gradient descent promotes solution with low-rank, and validate the conjecture saying that the phenomenon has to be addressed from a dynamical perspective.

description: Flat bands imply lack of itinerancy due to some constraints that, in principle, results in anomalous behaviors with randomness. By a molecular orbital (MO) representation of the flat band systems, random MO models are introduced where the degeneracy due to the flat bands is preserved even with randomness. The zero modes of the chiral symmetric system with sublattice imbalance belong to the class. After explaining the generic flat band construction by MOs, several examples are discussed with numerical demonstration as sawtooth lattice in one dimension and hyper-Pyrochlore lattice in any $d$-dimensions that extends the Kagome ($d=2$) and Pyrochlore ($d=3$) lattices to general dimensions.

description: Recent studies of methanol and ground-state OH masers at very high spectral resolution have shed new light on small-scale maser processes. The nearby source W3(OH), which contains numerous bright masers in several different transitions, provides an excellent laboratory for high spectral resolution techniques. We present a model of W3(OH) based on EVN observations of the rotationally-excited 6030 and 6035 MHz OH masers taken at 0.024 km/s spectral resolution. The 6.0 GHz masers are becoming brighter with time and show evidence for tangential proper motions. We confirm the existence of a region of magnetic field oriented toward the observer to the southeast and find another such region to the northeast in W3(OH), near the champagne flow. The 6.0 GHz masers trace the inner edge of a counterclockwise rotating torus feature. Masers at 6030 MHz are usually a factor of a few weaker than at 6035 MHz but trace the same material. Velocity gradients of nearby Zeeman components are much more closely correlated than in the ground state, likely due to the smaller spatial separation between Zeeman components. Hydroxyl maser peaks at very long baseline interferometric resolution appear to have structure on scales both smaller than that resolvable as well as on larger scales.

Electron dynamics in noncommutative geometry with magnetic field and Zitterbewegung phenomenon

description: Starting from a gauge invariant Dirac Hamiltonian with noncommutativity of space sector in the presence of an external uniform magnetic field, the resulting Dirac equation has been solved for electrons and its corresponding zitterbewegung (ZBW) phenomenon has been studied. The corresponding energy spectrum is shown to be different from previous studies wherein the non-gauge invariant Dirac Hamiltonian has been used. The effects of noncommutativity alter the amplitude as well as the cyclotron and the ZBW frequencies of the average velocity of charge carriers. This result is contrary to previous studies wherein there was no magnetic field and hence, neither the amplitude nor the frequency of the motion was affected. Moreover, all of the ZBW frequencies of the Landau energy-levels appear in the results. Also, in weak magnetic fields, we have calculated the average velocity of charge carriers for two initially localized spin-up and spin-down cases. The plotted trajectories reveal difference between these two cases. In addition, the ZBW phenomenon has been shown that manifests itself as a circular motion whose direction is spin dependent while accompanied by the cyclotron motion.

description: Quantum protocols will be more efficient with high-dimensional entangled states. Photons carrying orbital angular momenta can be used to create a high-dimensional entangled state. In this paper we experimentally demonstrate the entanglement of the orbital angular momentum between the Stokes and anti-Stokes photons generated in a hot atomic ensemble using spontaneous four-wave-mixing. This experiment also suggests the existence of the entanglement concerned with spatial degrees of freedom between the hot atomic ensemble and the Stokes photon.

description: Efficient and compact frequency converters are essential for frequency stabilization of terahertz sources. In this paper, we present a 3.5-THz, x6-harmonic, integrated Schottky diode mixer operating at room temperature. The designed frequency converter is based on a single-ended, planar Schottky diode with a sub-micron anode contact area defined on a suspended 2-$μ$m ultra-thin GaAs substrate. The dc-grounded anode pad was combined with the radio frequency E-plane probe, which resulted in an electrically compact circuit. At 200 MHz intermediate frequency, a mixer conversion loss of about 59 dB is measured and resulting in a 40 dB signal-to-noise ratio for phase locking 3.5-THz quantum-cascade laser. Using a quasi-static diode model combined with electromagnetic simulations, good agreement with the measured results was obtained. Harmonic frequency converters without the need of cryogenic cooling will help in the realization of highly sensitive space and air-borne heterodyne receivers.

Superconducting Mixer Technology at NAOJ

description: Over the past 15 years, the microfabrication facility at the National Astronomical Observatory of Japan has contributed to the development of various low noise receivers in the frequency range 0.1–1 THz.  Specializing in the fabrication of superconducting tunnel junction mixers, the laboratory maintains high performance equipment for thin film deposition and lithographic patterning.  Recent development studies have resulted in state-of-the-art Nb/AlNx/Nb junctions with current densities up to 50 kA/cm2 and low sub-gap leakage, thereby enabling the realization of mixers with much increased RF and IF bandwidths.  As future generation devices require a higher level of integration, f.ex. combining multiple mixer circuits on one chip, reproducibility and uniformity of junction parameters across the wafer become demanding issues.  To that end, further optimization of fabrication processes like film growth, photo resist definition and dry etching is an ongoing effort.

description: As most classical fluidization technologies, Circulating Fluidized Beds (CFB) are widely employed in chemical and physical operations. However, CFB Reactors still have some disadvantages such as the non-uniform solid particles distribution and the backflow of the solid particles near the wall, which deteriorate the system mixing, and lead to low system conversion/heat and mass transfer rate. To improve the CFB performance, we propose in the current work to study the effect of the ring baffle configuration on the fluidization system hydrodynamics using a multifluid Eulerian CFD model, incorporating the Kinetic Theory of Granular Flow. In this approach, two different types of ring baffles, circular and trapezoidal, were considered and the corresponding results were compared. The results revealed that the incorporation of ring baffles improved the system mixing and reduced the backflow near the wall. Nevertheless, the shape of baffles had a limited impact on the system hydrodynamics.

description: This paper focuses on developing a novel hybrid-haptic (nHH) device with a remote center of rotation with 4 DOFs (degrees of freedom) intendant to be used as a haptic device. The new architecture is composed of two chains handling each one a part of the motions. It has the advantages of a parallel robot as high stiffness and accuracy, and the large workspace of the serial robots. The optimal synthesis of the nHH was performed using real-coded genetic algorithms. The optimization criteria and constraints were established and successively formulated and solved using a mono-objective function. A validation and comparison study were performed between the spherical parallel manipulator and the nHH. The obtained results are promising since the nHH is compared to other similar task devices, such as spherical parallel manipulator, and presents a suitable kinematic performance with a task workspace free singularity inside.

Some factors affecting the development and expression of escape behavior in the guppy (Poecilia reticulata)
Creators: name: Goodey, Wayne
Publisher: name: University of British Columbia
Year: 2010

description: Adult guppies (Poecilia reticulata) frequently chase, but only infrequently capture and eat, young conspecifics. On average, young in planted tanks containing 6-14 adults and 1-4 young experienced over 270 chases per individual per day. Does the experience of being chased affect escape behavior? I tested this in two experiments on individual guppies. In the first, the escape behavior of three groups of guppies - control fish (those chased by adults in the first 48 hr of life), partially experienced fish (exposed to chemical cues from chasing adults, visual cues from chasing adults, or chemical cues from predatory fish), and inexperienced fish - was compared for their response to an aerial predator stimulus. Response intensity varied among the treatments, but deprivation had no effect on the appearance of stereotyped escape behaviors. Deprivation had no influence on the drop response elicited by the aerial stimulus, but it caused a general increase in the length of time spent freezing in response to the stimulus. Fish exposed to chemical cues from adult guppies, on the other hand, developed a near-control response. In the second experiment, I exposed guppies from the same experience groups to predation to see if long freezing times were selected against. Controls were not attacked with greater latency nor did they survive longer than any deprived group, but it took more attacks to kill control fish than to kill any deprived fish. I propose that chasing by adults is an ontogenetic mechanism for conditioning the young to avoid predation. This is selected for because guppies which are chased as juveniles survive better than those not chased as juveniles.

description: In quantum materials research, thermodynamic measurements are a key tool for probing the underlying physics of materials. The highest quality samples are often only available as microcrystals of typical mass < 100 μg. Heat capacity measurements on such small samples are beyond the scope of conventional set-ups but have been demonstrated in membrane-based calorimeters. This motivates the development of a nanocalorimeter to measure microcrystals of order nJ/K heat capacity, at ultra low temperature and high magnetic field. A key challenge of such a nanocalorimeter is the need for effectively primary thermometry, to diagnose any decoupling of the sample thermometer from the environment. This aim is realised by implementing the technique of Coulomb blockade thermometry (CBT) onto a membrane-based calorimeter. The proof of principle of this novel nanocalorimeter is shown by the successful fabrication and measurement of sensitive CBT structures onto a 200 nm thin silicon nitride membrane. The nanocalorimeter accuracy is tested by measuring the well-studied material Sr₃Ru₂O₇ [1,2]. We successfully measure a Sr₃Ru₂O₇ microcrystal with heat capacity of ~3 nJ/K, and find remarkably good agreement with literature measurements on samples three orders of magnitude larger. The newly developed nanocalorimeter is then applied to measure the topical material CeRh₂As₂, a heavy-fermion superconductor with a rare field induced transition [3]. The CeRh₂As₂ phase diagram is well studied, however reported phase transitions have significant widths of > 10% of the transition temperatures. We measure a CeRh₂As₂ microcrystal with the intention of observing reduced disorder broadening. Indeed we consistently observe sharper and more distinct transitions than comparable specific heat measurements on larger samples [4]. For the superconducting transition we determine Tc = 0.36 K, which is higher than previously reported for a larger crystal of the same growth generation [4]. The phase diagram we present shows the intersection of putative QDW transition line with the SC dome at 6 T. Furthermore, low temperature field dependent specific heat and analysis of ΔC/C hint at the possibility of three distinct regimes within the SC dome. With further improvements to the next generation of nanocalorimeter, these details will be investigated further.

description: Tetanic stimulations when applied to the Schaffer collaterals or the commissural input to CA₁ neurones in the mammalian hippocampus results in a long-lasting potentiation (LLP) of synaptic transmission across the tetanized synapse (Andersen et al., 1977; Schwartzkroin and Wester 1975). The induction of LLP is dependent on the extracellular Ca⁺⁺ concentration (Dunwiddie and Lynch, 1979; Wigstrom et al., 1979) but whether it is generated pre- and/or postsynaptically is at present unresolved. Transient homo- and heterosynaptic depressions of the CA₁ population spike have been reported following low frequency (I-20 Hz) tetani to hippocampal inputs (Lynch et al., 1977; Alger et al., 1978) which precede the observation of homosynaptic LLP (Dunwiddie and Lynch, 1978). The present studies were conducted to 1) test the hypothesis of Baudry and Lynch (1980a) who think that LLP can be explained postsynaptically by a Ca⁺⁺ dependent increase in the number of transmitter receptors; 2) examine the effects of verapamil (a Ca⁺⁺ antagonist that blocks CA₁ neuronal Ca⁺⁺ currents [Griffith and Brown, 1982] without interfering with transmitter release [Nachshen and Blaustein, 1979]) on the induction of LLP and homo- and heterosynaptic depressions; 3) investigate the Ca⁺⁺ dependence of a decrease in presynaptic terminal excitability that is associated with LLP (Sastry, 1982) and 4) examine the suggestion of Collingridge et al., (1983b) that N-methyl-DL-aspartate preferring amino acid receptors are involved in the induction of LLP. The studies conducted led to the conclusions that 1) LLP is probably generated presynaptically and depression of synaptic responses is localized to the postsynaptic neurone; 2) verapamil appears to antagonize Ca++-dependent depression postsynaptically but it does not block the induction of Ca⁺⁺ dependent LLP; 3) the decrease in excitability of Schaffer collateral terminal regions which correlates with LLP is Ca⁺⁺ dependent but insensitive to verapamil and 4) N-methyl-DL-aspartate preferring receptors are not involved in the induction of LLP.

description: Drone security is currently a major topic of discussion among researchers and industrialists. Although there are multiple applications of drones, if the security challenges are not anticipated and required architectural changes are not made, the upcoming drone applications will not be able to serve their actual purpose. Therefore, in this paper, we present a detailed review of the security-critical drone applications, and security-related challenges in drone communication such as DoS attacks, Man-in-the-middle attacks, De-Authentication attacks, and so on. Furthermore, as part of solution architectures, the use of Blockchain, Software Defined Networks (SDN), Machine Learning, and Fog/Edge computing are discussed as these are the most emerging technologies. Drones are highly resource-constrained devices and therefore it is not possible to deploy heavy security algorithms on board. Blockchain can be used to cryptographically store all the data that is sent to/from the drones, thereby saving it from tampering and eavesdropping. Various ML algorithms can be used to detect malicious drones in the network and to detect safe routes. Additionally, the SDN technology can be used to make the drone network reliable by allowing the controller to keep a close check on data traffic, and fog computing can be used to keep the computation capabilities closer to the drones without overloading them.

description: The E1(T=1) isovector dipole giant resonance (GDR) in heavy and super-heavy deformed nuclei is analyzed over a sample of 18 rare-earth nuclei, 4 actinides and three chains of super-heavy elements (Z=102, 114 and 120). Basis of the description is self-consistent separable RPA (SRPA) using the Skyrme force SLy6. The self-consistent model well reproduces the experimental data (energies and widths) in the rare-earth and actinide region. The trend of the resonance peak energies follows the estimates from collective models, showing a bias to the volume mode for the rare-earths isotopes and a mix of volume and surface modes for actinides and super-heavy elements. The widths of the GDR are mainly determined by the Landau fragmentation which in turn is found to be strongly influenced by deformation. A deformation splitting of the GDR can contribute about one third to the width and about 1 MeV further broadening can be associated to mechanism beyond the mean-field description (escape, coupling with complex configurations).

description: We have reanalyzed the microscopic origin of the isotropic deviations that are observed from the energy spacings predicted by the HDVV Hamiltonian. Usually, a biquadratic spin operator is added to the HDVV Hamiltonian to account for such deviations. It is shown here that this operator cannot describe the effect of the excited atomic non-Hund states which brought the most important contribution to the deviations. For systems containing more than two magnetic centers, non-Hund states cause additional interactions that are of the same order of magnitude as the biquadratic exchange and should have significant effects on the macroscopic properties of extended systems.

description: Point clouds have attracted increasing attention. Significant progress has been made in methods for point cloud analysis, which often requires costly human annotation as supervision. To address this issue, we propose a novel self-contrastive learning for self-supervised point cloud representation learning, aiming to capture both local geometric patterns and nonlocal semantic primitives based on the nonlocal self-similarity of point clouds. The contributions are two-fold: on the one hand, instead of contrasting among different point clouds as commonly employed in contrastive learning, we exploit self-similar point cloud patches within a single point cloud as positive samples and otherwise negative ones to facilitate the task of contrastive learning. On the other hand, we actively learn hard negative samples that are close to positive samples for discriminative feature learning. Experimental results show that the proposed method achieves state-of-the-art performance on widely used benchmark datasets for self-supervised point cloud segmentation and transfer learning for classification.

 This species has sub-spatulate setae, dorsolaterals and h 1 set on very weak tubercles, dorsocentrals c1, d1, e1 and f1 not set on tubercles. Solenidion of loosely associated setae on tarsus I about two thirds length of proximal tactile seta whereas that of tarsus II is same length or slightly longer than proximal tactile seta. Dorsal striations faint compared to other two species of Eutetranychus examined.
Leg chaetotaxy as follows: tarsi 12(1)-10(1)-8(1)-8(1); tibiae 9(1)-6-5-6; genua 5-5-2-2; femora 8-6-2-1; coxae 2-2-1-1.
 Specimens examined: Three females and one male collected on Ficus burkei (Moraceae) from Alupe area, Busia district (N00°29.870'; E034°07.732') and two females collected on Ricinus communis (Euphorbiaceae) from Marigat, Baringo district (N00°28.132'; E036°00.906').
 Remarks: This species was first recorded on Ficus sp. and Morus sp. from South Africa (Meyer, 1974). It has been reported from several Ficus species and it seems to show preference for the members of the family Moraceae. This species has previously been reported from South Africa only and thus its distribution records are still very limited. They are grey in colour

description: We study the gravitational corrections to the Maxwell, Dirac and Klein-Gorden theories in the large extra dimension model in which the gravitons propagate in the (4+n)-dimensional bulk, while the gauge and matter fields are confined to the four-dimensional world. The corrections to the two-point Green's functions of the gauge and matter fields from the exchanges of virtual Kaluza-Klein gravitons are calculated in the gauge independent background field method. In the framework of effective field theory, we show that the modified one-loop renormalizable Lagrangian due to quantum gravitational effects contains a TeV scale Lee-Wick partner of every gauge and matter field as extra degrees of freedom in the theory. Thus the large extra dimension model of gravity provides a natural mechanism to the emergence of these exotic particles which were recently used to construct an extension of the Standard Model.

description: We calculate the exchange coupling J between electrons in a double-well potential in a two-dimensional semiconductor environment within the Heitler-London (HL) approach. Two functional forms are considered for the double-well potential. We show that by choosing an appropriate and relatively simple single-electron variational wave function it is possible, within the HL approach, to significantly improve the estimates for J. In all cases the present scheme overcomes the artifacts and limitations at short interdot distances, previously attributed to the HL method, where unphysical triplet ground states have been found, and leads to an overall agreement with analytic interpolated expressions for J obtained for a donor-type model potential.

description: As a test of general relativity on cosmological scales, we measure the γparameter for the growth rate of density perturbations using the redshift-space distortion of the luminous red galaxies in the Sloan Digital Sky Survey (SDSS). Assuming the cosmological constant model, which matches the results of the WMAP experiment, we find γ=0.62+1.8(σ_8-0.8) \pm 0.11 at 1-sigma confidence level, which is consistent with the prediction of general relativity, γ\simeq0.55\sim0.56. Rather high value of σ_8(\geq0.87) is required to be consistent with the prediction of the cosmological DGP model, γ\simeq0.68.

description: One of the major challenges in the science of maxillofacial radiology imaging is the various artifacts created in images taken by cone beam computed tomography (CBCT) imaging systems. Among these artifacts, motion artifact, which is created by the patient, has adverse effects on image quality. In this paper, according to the conditions and limitations of the CBCT imaging room, the goal is the design and development of a cable-driven parallel robot to create repeatable movements of a dry skull inside a CBCT scanner for studying motion artifacts and building up reference datasets with motion artifacts. The proposed robot allows a dry skull to execute motions, which were selected on the basis of clinical evidence, with 3-degrees of freedom during imaging in synchronous manner with the radiation beam. The kinematic model of the robot is presented to investigate and describe the correlation between the amount of motion and the pulse width applied to DC motors. This robot can be controlled by the user through a smartphone or laptop wirelessly via a Wi-Fi connection. Using wireless communication protects the user from harmful radiation during robot driving and functioning. The results show that the designed robot has a reproducibility above 95% in performing various movements.
