description: The ongoing development of the space-based laser interferometer missions is aiming at unprecedented gravitational wave detections in the millihertz frequency band. The spaceborne nature of the experimental setups leads to a degree of subtlety regarding the otherwise overwhelming laser frequency noise. The cancellation of the latter is accomplished through the time-delay interferometry technique. Moreover, to eventually achieve the desired noise level, the phase fluctuations of the onboard ultra-stable oscillator must also be suppressed. This can be fulfilled by introducing sideband signals which, in turn, give rise to an improved cancellation scheme accounting for the clock-jitter noise. Nonetheless, for certain Sagnac-type interferometry layouts, it can be shown that resultant residual clock noise found in the literature can be further improved. In this regard, we propose refined cancellation combinations for two specific clock noise patterns. This is achieved by employing the so-called geometric time-delay interferometry interpretation. It is shown that for specific Sagnac combinations, the residual noise diminishes significantly to attain the experimentally acceptable sensitivity level. Moreover, we argue that the derived combination, in addition to the existing ones in the literature, furnishes a general-purpose cancellation scheme that serves for arbitrary time-delay interferometry combinations. The subsequential residual noise will only involve factors proportional to the commutators between the delay operators. Our arguments reside in the form of the clock noise expressed in terms of the coefficients of the generating set of the first module of syzygies, the linear combination of which originally constitutes the very solution for laser noise reduction.

description: Damping in 2D and 3D dilute gases is investigated using both the hydrodynamical approach and the Hartree-Fock-Bogoliubov (HFB) approximation . We found that the both methods are good for the Beliaev damping at zero temperature and Landau damping at very low temperature, however, at high temperature, the hydrodynamical approach overestimates the Landau damping and the HFB gives a better approximation. This result shows that the comparison of the theoretical calculation using the hydrodynamical approach and the experimental data for high temperature done by Vincent Liu (PRL {\bf21} 4056 (1997)) is not proper. For two-dimensional systems, we show that the Beliaev damping rate is proportional to $k^3$ and the Landau damping rate is proportional to $ T^2$ for low temperature and to $T$ for high temperature. We also show that in two dimensions the hydrodynamical approach gives the same result for zero temperature and for low temperature as HFB, but overestimates the Landau damping for high temperature.

description: We perform molecular dynamics and Monte Carlo simulations of two-dimensional melting with dipole-dipole interactions. Both static and dynamic behaviors are examined. In the isotropic liquid phase, the bond orientational correlation length 6 and susceptibility 6 are measured, and the data are fitted to the theoretical ansatz. An algebraic decay is detected for both spatial and temporal bond orientational correlation functions in an intermediate temperature regime, and it provides an explicit evidence for the existence of the hexatic phase. From the finite-size scaling analysis of the global bond orientational order parameter, the disclination unbinding temperature Ti is estimated. In addition, from dynamic Monte Carlo simulations of the positional order parameter, we extract the critical exponents at the dislocation unbinding temperature Tm. All the results are in agreement with those from experiments and support the Kosterlitz-Thouless-Halperin-Nelson-Young (KTHNY) theory.

description: An energy-based liquid-vapor interface detection method is presented using molecular dynamics (MD) simulations of liquid menisci confined between two parallel plates under equilibrium and evaporation/condensation conditions. This method defines the liquid-vapor interface at the location where the kinetic energy of the molecules first exceeds the total potential energy imposed by all neighboring (liquid, vapor, and solid) atoms. This definition naturally adapts to the location of the menisci relative to the walls and can properly model the behavior of the liquid adsorbed layers. Unlike the density cutoff methods frequently used in the literature that suffer from density layering effects, this new method gives smooth and continuous liquid-vapor interfaces in nanoconfinements. Surface tension values calculated from the equilibrium MD simulations match the Young-Laplace equation better when using the radius of curvatures calculated from this method. Overall, this energy-based liquid-vapor interface detection method can be used in studies of nanoscale phase change processes and other relevant applications.

description: Two parapatric species of Lema Fabricius, 1798 infest orchids in India. Lema (Petauristes) pectoralis unicolor Clark, 1866 distributed throughout the Indo-Malayan area, China and Nepal feeds on orchids in northeast India, while L. (Petauristes) yerburyi Jacoby, 1908 is associated with orchids in south India and the Andaman & Nicobar Islands. External morphology and female and male genitalia, including endophallus, of L. yerburyi are described and illustrated. The developmental period of L. yerburyi from egg to adult range from 19 to 24 days, with an egg period of 2–5 days, a larval period of 5–9 days and a pupal period of 10–14 days. The adults live for 68–187 days. New host plant records of L. yerburyi include different commercial varieties of orchids in the genera Arachnis, Ascocenda, Dendrobium, Mokara, Oncidium and Phalaenopsis (all Orchidaceae). The feeding scars turned necrotic, and dried up and the infested flowers, flower buds, tender inflorescence stalks, leaves and roots dried up. Adults exhibited thanatosis. Stridulation occurred when a beetle was disturbed by another beetle, food was inadequate, due to other external disturbances or for no apparent reason. Tetrastichus sp. nr julis (Walker) (Eulophidae) and Goryphus Holmgren, 1868 (Ichneumonidae) parasitised the grown up larvae and the adult parasitoid emerged during the pupal stage. Nucleotide sequence of L. yerburyi is deposited in the GenBank (Accession no. PP667398).
Hybrid PLL Architectures and Implementations
Creators: Daniel Friedman
Publisher: name: IEEE
Year: 2020

SSCS Webinar Slides
Abstract- Depending on the target application and on implementation constraints, both conventional charge pump PLLs and high performance digital PLLs may be excellent implementation choices. Each design type offers significant technical advantages while also raising its own set of design challenges. For example, charge pump PLLs naturally provide a feedback signal that is linearly related to phase error, but typically demand the use of a physically large loop filter capacitor if lower loop bandwidths are desired. High performance digital PLLs solve the loop capacitor problem, but may require a high performance time-to-digital converter as part of the feedback linearization solution. This presentation will focus on the exploration of a hybrid PLL architecture, an approach which features an analog proportional path in combination with a digital integral path, thus in some way offering the best of both PLL worlds. The approach will be introduced and explored through the presentation of multiple high-performance integrated hybrid PLL implementations in deep submicron CMOS technologies.

description: Magnetohydrodynamic (MHD) turbulence is a crucial component of the current paradigms of star formation, dynamo theory, particle transport, magnetic reconnection and evolution of structure in the interstellar medium (ISM) of galaxies. Despite the importance of turbulence to astrophysical fluids, a full theoretical framework based on solutions to the Navier-Stokes equations remains intractable. Observations provide only limited line-of-sight information on densities, temperatures, velocities and magnetic field strengths and therefore directly measuring turbulence in the ISM is challenging. A statistical approach has been of great utility in allowing comparisons of observations, simulations and analytic predictions. In this review article we address the growing importance of MHD turbulence in many fields of astrophysics and review statistical diagnostics for studying interstellar and interplanetary turbulence. In particular, we will review statistical diagnostics and machine learning algorithms that have been developed for observational data sets in order to obtain information about the turbulence cascade, fluid compressibility (sonic Mach number), and magnetization of fluid (Alfvénic Mach number). These techniques have often been tested on numerical simulations of MHD turbulence, which may include the creation of synthetic observations, and are often formulated on theoretical expectations for compressible magnetized turbulence. We stress the use of multiple techniques, as this can provide a more accurate indication of the turbulence parameters of interest. We conclude by describing several open-source tools for the astrophysical community to use when dealing with turbulence.

Faster, Higher, Stronger – Efficient Energy Conversion with GaN Slides
Creators: Bernhard Wicht
Publisher: name: IEEE
Year: 2019

SSCS Webinar
ABSTRACT  Efficient conversion of energy is one of the megatrends, enabled by advanced semiconductors and microelectronics. As a wide-band gap material, GaN (gallium nitride) offers a huge potential to reduce the overall power electronics system size and cost. GaN technology is faster, smaller, more efficient than silicon power MOSFETs. Dedicated control circuits enable to leverage the potential of GaN power switches with a minimum of parasitic effects. This webinar gives an introduction into circuit and system design aspects related to GaN power transistors with a particular focus on gate drivers. Small solutions are achieved by increasing the switching frequency as it scales down passive components. The concept of high-voltage charge and energy storing enables highly integrated gate driver designs with a minimum of external components. Multi-level gate drivers increase the robustness under extremely fast switching transitions up to 500V/ns. Concepts for common-mode transient immunity (CMTI) are discussed.

title: Phosphinic acid synthesis
Creators: name: Andrew Boyd, E
Publisher: name: University of Kent
Year: 1990

description: Chapter 1 gives a background to the importance of phosphinic acids, and a description of their physical properties and chemical reactivity. A review of the more useful methods towards synthesis is given. At the end of the chapter, trivalent silyl phosphonite esters are introduced as potentially useful synthetic reagents. However, only limited work has performed using these species. Chapter 2 introduces the novel addition of bis(trimethylsilyl) phosphonite to c-unsaturated esters under basic silylating conditions. This reaction is optimised and transformed into a useful synthetic method for the preparation of phosphinic acids, named the "triethylammonium phosphinate reaction." Various other electrophiles were used as substrates in this reaction, little success was obtained. Theories are provided to explain side reactions and products, some additional reactions were performed to give evidence to support these theories. A novel reaction between a Nannich base and silyl phosphonite esters, yielding a phosphinic acid, is introduced. The problems of phosphinic acid purification by physical and chemical methods are discussed. Chapter 3 is concerned with the development of the "triethylammonium reaction" to allow addition of silyl phosphonite esters to a,-unsaturated ketones. The novel "sodium phosphinate" reaction was developed but little success was achieved, however excellent yields of phosphinic acids were obtained when a,-unsaturated esters were used as substrates. Chapter 4 is about developing a new reaction to allow phosphinic acid synthesis using vinyl ketones as substrates, under controlled conditions. This mild reaction was then combined with a novel method of purification forming adamantanammonium phosphinate esters. This flexible methodology was established by the preparation of a variety of substituted phosphinic acids and phosphinate esters. In chapter 5 adaption of the reaction discovered in chapter 4 was undertaken which, allows the synthesis of phosphinic acids using alkyl iodides. A useful reaction was developed which gives similar products to the Arbuzov reaction, however it is demonstrated that this new reaction does not proceed by the same mechanism. Chapter 6 gives an account of work undertaken to the phosphinate analogue of platelet activating factor. The original route was unsuccessful, reasons for this are discussed. A shorter alternative route is given, which relies on chemistry developed in this thesis. I have made an attempt to show the utility of the novel methodology contained in this thesis, by giving my ideas on proposed routes to the synthesis of some interesting phosphinate analogues. I consider some of these analogues to be useful biochemical tools.

Ill presents a survey of the main doctrines of the Vijnaptimatrata Yogacara school of Asafiga and Vasubandhu. As one branch of Mahayana Buddhism, the. school is shown to be best understood as a systematic soteriology characterized by an emphasis on the epistemic rather than the ontologic analysis of the constituents of experience (dhamas). This chapter concludes with a discussion of K'uei-chi's significance as a major figure in the development of Buddhist thought in East Asia. He is presented as a syncretist who sought to organize a manifold and complex tradition in a manner that would allow its transmission into a very different cultural context. Part Two consists of a translation of one essay from K'uei-chi's voluminous doctrinal compendium, the Forest of Doctrines in the Garden of the Dharma of Mahayana Buddhism (Ta-sheng fa-yuan i-lin ohang). Chapt. IV provides an introduction to the work, outlining the commentaries used, both contemporary and modern, and discussing the methodological problems confronted in translating the text. Chapter V is the translation itself: K'uei-chi's "Essay on Vijnaptimatrata" (Wei-shih chang) in ten sections. It includes extensive annotation indicating the sources of the ideas K'uei-chi discusses and providing supplementary information on the many Buddhist doctrines to which he refers.

Noise Lecture Series
Noise presents fundamental trade offs in circuit design, requiring a rigorous understanding of the noise properties of various circuit topologies. This lecture series begins with basic noise concepts and the noise models necessary for representing the behavior of resistors and transistors. It then deals with the analysis of noise in circuits and provides a methodical, intuitive approach. Next, the noise performance of basic amplifier stages is formulated and key insights are developed. Finally, these insights are applied to the design of low noise op amps and switched capacitor circuits

description: Invasive floral species can affect the native plant-pollinator interactions. While the impact of such invasives within native plant communities is extensively documented, the understanding of their ‘proximity’ effects – where invasive species spatially influence the pollinators of native biodiversity – remains comparatively obscure and requires further investigation. We quantified the impact of pollination dynamics associated with Erigeron karvinskianus, an invasive, on the pollination of the native flora in Nainital, western Himalaya. During 162 surveys, we explored the foraging dynamics of 33 native insects on E. karvinskianus across plots from six sites, subjected to two groups, Begonia crenata in proximity of E. karvinskianus and plots with B. crenata distant from E. karvinskianus. Apis cerana, Apis mellifera and Colias fieldii performed the major pollination and foraging was correlated with temperature and floral reward. We designed a mixed effects linear model (MELM) and found that the native plant had more flower visitor density when in close proximity to the landscapes invaded with the invasive E. karvinskianus. Our findings highlight that the ‘proximity effect’ of E. karvinskianus positively affects the floral pollinator visitation of native flora by enhancing their pollinator activity in invaded landscapes.

description: Using first-principles density functional calculations, we have studied the structural stability of stoichiometric as well as non-stoichiometric CdS nanoclusters at ambient pressure with diameters ranging up to about 2.5 nm. Our study reveals that the relative stability of the two available structures for CdS, namely zinc blende and wurtzite, depends sensitively on the details like surface geometry and/or surface chemistry. The associated band gap also exhibits non-monotonic behavior as a function of cluster size. Our findings may shed light on reports of experimentally observed structures and associated electronic structures of CdS nanoclusters found in the literature.

description: The existence probability $E_p$ and the percolation probability $P$ of the bond percolation on rectangular domains with different aspect ratios $R$ are studied via the mapping functions between systems with different aspect ratios. The superscaling behavior of $E_p$ and $P$ for such systems with exponents $a$ and $b$, respectively, found by Watanabe, Yukawa, Ito, and Hu in [Phys. Rev. Lett. \textbf{93}, 190601 (2004)] can be understood from the lower order approximation of the mapping functions $f_R$ and $g_R$ for $E_p$ and $P$, respectively; the exponents $a$ and $b$ can be obtained from numerically determined mapping functions $f_R$ and $g_R$, respectively.

description: Persistent arterial hypertension (AHT) plays a very important role in the development of cardiovascular diseases (CVD). The present study assessed the vasodilator activities of the methanol extract (ME) and its fractions obtained from leaves of a Mexican Crataegus rosei plant. The fat- and tannin-free ME fraction (FTFME) produced the most potent vasodilator effect [EC50 8.253 (4.672 to 14.58 μg/mL)], that was 6.7-fold higher than that of the ME [EC50 = 55.49 (29.78 to 68.69) μg/mL], which was similar to that of ACh used as a positive control. This effect was dependent on the nitric oxide/cGMP pathway. Six triterpene acids (ursolic, oleanolic, euscaphic, maslinic, corosolic, and alphitolic) were identified as the main constituents of this fraction. In contrast to the commercially available Crataegus extracts, these compounds must be the most suitable chemical and pharmacological markers for this methanol extract in research into obtaining a standardised antihypertensive extract.

description: The magnetic moments and magnetic anisotropy energy (MAE) of CoRh alloy nanoparticles are determined experimentally and theoretically. Non-trivial correlations between chemical order, magnetic order and MAE are revealed. A remarkable non-monotonous dependence of the MAE as a function of composition and chemical order is observed that opens novel possibilities of tuning the magnetic properties of nanoalloys. The observations are successfully compared and analyzed with our electronic calculations. In this way we clearly demonstrate that the induced 4d moments and the 3d-4d interfaces are the key parameters controlling the magneto-anisotropic behavior.

Anatomical and biochemical organization of the basal ganglia
Creators: name: Nagy, James Imre
Publisher: name: University of British Columbia
Year: 2010

description: The biochemistry and anatomy of various nuclei of the basal ganglia of the rat were investigated. The head of the striatum was found to project to the anterior globus pallidus (GP) and to the entopeduncular nucleus (EP). A projection from the anterior striatum to the substantia nigra (SN) was confirmed. The tail of the striatum was found to project to the posterior part of the GP. No anatomical evidence was obtained for a projection from the tail of the striatum to the EP. The posterior striatum was found to project to the lateral SN. Biochemically, the presence of glutamic acid decarboxylase (GAD) in the projection from the head of the striatum to the GP has been confirmed. The head and tail of the striatum were found to project GAD-containing fibers to the EP. While the absence of nigral GAD-containing afferents originating in the anterior striatum has been confirmed, it was found that the SN does receive such afferents from more posterior regions of the striatum. The SN was found to be devoid of a GAD-containing input from the GP. The EP efferents to the habenula were found to be GAD-containing. Preliminary evidence was obtained for the presence of cholinergic fibers in the striatal projections to the GP and EP. The cellular localization of various enzyme systems in the SN and of the dopamine (DA) receptor in the SN and striatum was investigated using kainic acid and 6-hydroxydopamine lesion techniques. It was concluded that choline acetyltransferase and DA-sensitive adenylate cyclase are contained in nigral afferents, acetylcholinesterase is contained in both nigral afferents and intrinsic neuronal elements and tyrosine hydroxylase is contained in nigral perikarya. The results concerning nigral GAD were inconclusive. Evidence was obtained for the existence of DA receptors on DA-containing neurons in the SN and their terminals in the striatum.
