description: The holy grail for quantum engineers and scientists is to build the quantum internet that spans over the entire globe. This information infrastructure holds the promise for transmitting information securely, scaling up computing power exponentially and setting the standards for precision measurement at the ultimate limit. Solid-state-based spin systems recently emerge as promising building blocks for the quantum internet. Among these candidates, the negatively charged nitrogen vacancy (NV) center in diamond attracted much attention thanks to its optical addressability, long spin coherence times, and well-controlled electronic orbitals and spin states. However, the non-ideal optical properties of NV poses a challenge to its implementation in quantum technologies. This calls for building photonic structures as efficient spin-photon interfaces for realizing strong interactions with photon modes or efficient out-coupling of its fluorescence. Such interfacing structures are also of great importance for other optically active spin-systems newly found.
      In this dissertation, chirped dielectric cavities are designed for building NV as fast single photon sources via broadband Purcell enhancement, using an inverse simulation approach to maximize the broadband absorption of the atomically thin absorbers. Simulated NV-cavity coupling indicates broadband Purcell factor of ∼> 100. Next, to realize coupled NV-cavity systems over large scale, a self-aligned nano-implantation technique is investigated using a lithographically defined hybrid mask for both precision pattern transfer and nitrogen implantation. Measured results show single-NV per cavity yield of ∼ 26±1% and 5-fold Purcell induced intensity enhancement. Finally, chirped circular gratings are designed for efficient collection from the NV for remote entanglement and precision sensing. Simulated grating structures present near-unity collection efficiencies. These demonstrated techniques and structures are also applicable to other solid-state-based spin systems.

Small-area molecular clouds without shielding

Publisher: name: arXiv
Year: 2002
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Using the IRAM 30m telescope two molecular structures have been detected which cover very small areas, FWHM<1'. The clouds have velocities of v_lsr~5kms and linewidth of dv~0.8km/s; thus they belong most likely to the Milky Way. Applying standard conversion factors one finds that even at the upper distance limit of 2200pc the structures are low mass objects (M=(1-6)x10^{-4}(d/100pc)^2Msun) which are not gravitationally virialized. HI 21cm line data towards the clouds show no prominent HI clouds. The total HI column densities for both structures are below N(HI)<2.1x10^{20}cm^{-2}, corresponding to A_V<0.2mag, assuming a standard gas-to-dust ratio. IRAS 100micron data towards the structures show also only low emission, consistent with low extinction. Unless there is unseen cold dust associated with the structures this shielding is too low for the structures to survive the interstellar radiation field for a long time. The detection of 2 such structures in a rather limited sample of observations suggests that they could be a rather common feature in the interstellar medium, however, so far not recognized as such due to the weakness of their lines and their small extent.

This appeared to be morphologically similar to N. brevilabiata and N. atzi. Further specimens are required to confirm the species identification therefore this species is tentatively identified as Narcine sp. (Figure 14). (sensu Psomadakis et al. 2020).

description: The existence of the theory of `twisted cotangent bundles' (symplectic groupoids) allows to study classical mechanical systems which are generalized in the sense that their configurations form a Poisson manifold. It is natural to study from this point of view first such systems which arise in the context of some basic physical symmetry (space-time, rotations, etc.). We review results obtained so far in this direction.

description: NOTHOLEBIAS GEN. NOV.   Type species: Cynolebias minimus Myers, 1942.
 Diagnosis: Distinguished from all other genera of Cynopoecilina (Leptolebias, Cynopoecilus, and Campellolebias) by the possession of dermosphenotic (vs. dermosphenotic absent), basihyal narrow, roughly rectangular (Fig. 3) (vs. wide, triangular), welldeveloped contact organs on most inner surface of pectoral fin in males (vs. contact organs reduced or absent), opercular region with red bars in males (Fig. 11) (vs. red reticulation), and iridescent bars or vertical lines on caudal fin in males (Fig. 11) (vs. bars absent). Also differs from Leptolebias in having teeth on second pharyngobranchial (teeth absent), caudal fin subtruncate to rounded, short, deeper than long (Fig. 11) (vs. elliptical to lanceolate, longer than deep), two anterior supraorbital neuromasts (vs. single anterior supraorbital neuromast), and dark pigmentation extending over entire dorsal fin in males (vs. not extending to distal third of dorsal fin).
 Included species: Notholebias minimus (Myers) comb. nov.; Notholebias fractifasciatus (Costa) comb. nov.; and Notholebias cruzi (Costa) comb. nov.
 Distribution: Coastal plains of south-eastern Brazil, between the São João river floodplains and Itaguaí, Rio de Janeiro state.
 Etymology: The name Notholebias is an allusion to the superficial resemblance between species included in the new genus and some species of the African killifish genus Nothobranchius Peters, 1868, in particular Nothobranchius lourensi Wildekamp, 1977, which have similar colour patterns and similar body proportions (from the Greek nothos = false, taken from the name Nothobranchius, and lebias = small fish, a name often used to compose generic names of rivulid fishes). Gender masculine.

description: This work proposes a robust data-driven tube-based zonotopic predictive control (TZPC) approach for discrete-time linear systems, designed to ensure stability and recursive feasibility in the presence of bounded noise. The proposed approach consists of two phases. In an initial learning phase, we provide an over-approximation of all models consistent with past input and noisy state data using zonotope properties. Subsequently, in a control phase, we formulate an optimization problem, which by integrating terminal ingredients is proven to be recursively feasible. Moreover, we prove that implementing this data-driven predictive control approach guarantees robust exponential stability of the closed-loop system. The effectiveness and competitive performance of the proposed control strategy, compared to recent data-driven predictive control methods, are illustrated through numerical simulations.

description: The purpose of this article is to compare alignment outcomes following pediatric strabismus surgery for simple horizontal strabismus in patients with state-based aid, used as a proxy for lower socioeconomic status (SES) with those with private insurance. Medical records of all children treated with horizontal strabismus surgery over a period from 2014-17 were retrospectively reviewed. Medical assistance was used as a proxy for lower SES. Patients were compared to a control population undergoing similar surgery by same surgeons in the same time period. Data points were collected at preoperative and postoperative month 6 visits. Improvement in alignment was the primary outcome variable. Improvement in fusion, amblyopia, and stereopsis were also examined. Demographic information and compliance with treatment recommendations were recorded. 69 patients met inclusion criteria from a total population of 105 patients; 36 were excluded due to loss to follow-up. This was compared to a control group with private insurance; 34 patients were identified out of a total of 38, 4 patients were lost to follow-up. Overall rate of operative success was 71.0% at POM6. Overall rate of success for control group was 73.5%. The difference failed to be statistically significant (p = 0.37). Race, sex, age at time of surgery, and type of strabismus (esotropia, exotropia) failed to correlate with success rate of surgery. Poor compliance with prescribed treatments (glasses, patching/atropine) in both groups correlated with surgical failure. 68.1% of study patients and 70.6% of control reported good compliance with treatment. We present the first analysis of the impact of SES on strabismus surgery outcomes. Overall surgical success rate in our study population failed to differ significantly from a control population and were comparable to that reported in the literature. We found that compliance with treatment influenced surgical success rates in our study population. The high rate of lost to follow-up in the study population is an important factor influencing our conclusion that no difference exists between our groups.

By giving rigorous mathematical definitions of reference frames and of the Principle of Relativity (PR) we prove that physical realizations of the $v > 1$ solutions of, e.g., the Maxwell equations imply in a breakdown of the PR, but in no contradiction at all with known physical facts.

The Multi-Band Magnification Bias for Gravitational Lenses

description: We present a generalization of the concept of magnification bias for gravitationally-lensed quasars, in which the quasars are selected by flux in more than one wavelength band. To illustrate the principle, we consider the case of two-band selection, in which the fluxes in the two bands are uncorrelated, perfectly correlated, or correlated with scatter. For uncorrelated fluxes, we show that the previously-held result - that the bias is the product of the single-band biases - is generally false. We demonstrate some important properties of the multi-band magnification bias using model luminosity functions inspired by observed correlations among X-ray, optical, infrared and radio fluxes of quasars. In particular, the bias need not be an increasing function of each flux, and the bias can be extremely large for non-linear correlations. The latter fact may account for the high lensing rates found in some X-ray/optical and infrared/radio selected samples.

description: The dedicated gas hydrate coring/drilling program was carried out under National Gas Hydrate Program (NGHP) in four Indian offshore areas (Kerala-Konkan, Krishna- Godavari, Mahanadi and Andman) during 28th April to 19th August, 2006. During NGHP Expedition 01, 2006, total of 39 holes were drilled/cored at 21 sites in these areas. The gas hydrates have been found to be present in large quantities in Indian offshore areas particularly in KG basin. More than 130 confirmed solid gas hydrate samples were recovered during this hydrate coring/drilling program. The laboratory analysis was carried out on the 34 natural gas hydrate samples recovered from offshore India. The gas hydrate characterization was carried out using the microscopic techniques such as Raman, 13C NMR and XRD for its structure, cavity occupancy and hydration number. The gas hydrates occur in grayish green fine sediments, gray medium sands and white volcanic ash as pore-filling hydrate and massive hydrates in fractured shale/clay. The visible massive gas hydrates developed especially at Site NGHP 1-10B, 10C, 10D and 21A in K G area. The structures of the gas hydrates in the studied samples are all sI, with methane as the dominant guest molecule. The occupancy of methane in large cage is almost complete, while it is variable in the small cage (0.75 to 0.99). The hydration number is 6.10 ± 0.15 for most of the hydrates in the samples studied. This paper presents the results of the laboratory analysis on the structural characterization of natural gas hydrates in core samples from offshore India.

description: Human meprin-β, a zinc metalloprotease belonging to the astacin family, have been found to be associated with many pathological conditions like inflammatory bowel disease, fibrosis and neurodegenerative disease. The inhibition of meprin-β by various inhibitors, both macromolecular and small molecules, is crucial in the control of several diseases. Human fetuin-A, a negative acute phase protein involved in inflammatory disease, has recently been identified as an endogenous inhibitor for meprin-β. In this computational study, an integrated in silico approach was performed using existing structural information of meprin-β coupled with ab initio modelling of human fetuin-A to predict a rational model of the complex through protein–protein docking. Further, the models were optimized and validated to generate an ensemble of conformations through extensive molecular dynamics simulation. Virtual alanine scanning mutagenesis was explored to identify hotspot residues on both proteins significant for protein–protein interaction (PPI). The results of the study provide structural insight into PPI between meprin-β and fetuin-A which can be useful in designing molecules to modulate meprin-β activity. Communicated by Ramaswamy H. Sarma

description: The chemokine receptor CXCR4 contributes to tumour cell migration and invasion during the progression of prostate cancer. In particular, this pathway is central to the metastasis of prostate cancer to the bone marrow. Limited therapeutic options exist for prostate cancer patients who have progressed to advanced metastatic disease, and pharmacological interference of the chemokine network may serve to control tumour cell dissemination and the establishment of metastasis. A more detailed knowledge of the mechanisms regulating chemokine receptors is required, in order to further characterise and explore the capacity and effectiveness of targeting these pathways for therapeutic intervention in prostate cancer. Here, the regulation of CXCR4 protein expression and function was investigated in relation to androgens and the extracellular matrix. Accumulating evidence of CXCR4 regulation by androgens and the androgen receptor have indicated that androgens not only promote the growth and development of prostate cancer, but may actively contribute to the metastatic progression of prostate through modulation of the chemokine network. In the current study, the endogenous protein expression and functionality of the androgen receptor were firstly characterised in the androgen-insensitive prostate cancer cell lines DU145 and PC3, using the androgen-sensitive LNCaP cells as a basis for comparison. Investigations were performed using two-dimensional culture in conjunction with the more physiologically relevant three-dimensional in vitro culture model.

description: We show that heavy ion collisions at the LHC provide a promising environment to search for signatures with displaced vertices in well-motivated New Physics scenarios. Compared to proton collisions, they offer several advantages, i) the number of parton level interactions per collision is larger, ii) there is no pile-up, iii) the lower instantaneous luminosity compared to proton collisions allows to operate the LHC experiments with very loose triggers, and iv) there are new production mechanisms that are absent in proton collisions. In the present work we focus on the third point and show that the modification of the triggers alone can increase the number of observable events by orders of magnitude if the long lived particles are predominantly produced with low transverse momentum. Our results show that collisions of ions lighter than lead are well-motivated from the viewpoint of searches for New Physics. We illustrate this for the example of heavy neutrinos in the Neutrino Minimal Standard Model.

Efforts toward the Total Synthesis of Cyclocitrinol

description: Natural products featuring bridged seven- and eight-membered ring systems are relatively rare in nature; however, due to their interesting biological activity, they are commonly found in pharmaceuticals. Despite their importance, no general method to access bicyclic ring systems exists, thus the de novo synthesis of these complex molecules is often a significant challenge. It was with this in mind that we launched our efforts towards the first total synthesis of cyclocitrinol, a unique steroid with a fused ring system possessing a rare bicyclo[4.4.1]undec-7,10-diene A/B ring with a bridgehead double bond. Using knowledge gained from previous model studies of a strain-accelerated tandem Ireland-Claisen/Cope rearrangement to assemble the ABC tricyclic core, two approaches towards the completion of the molecule were explored: 1) an Ireland-Claisen/Cope/Claisen rearrangement followed by RCM and 2) a 1,3-allylic transposition/RCM. Of these approaches, the later, led to the completion of the ABCD tetracyclic core and installation of the fully elaborated C17 side-chain.

description: The flow assurance industry is progressively moving away from avoidance of hydrate formation towards risk management. Risk management allows hydrates to form but prevents hydrates from agglomerating and forming a plug, or delays hydrate formation within the timescale of the residence time of the water in the hydrate-prone section of the flow line. A key factor in risk management for an oil-dominated system is the stability of the emulsified water with gas hydrate formation. It is shown using Differential Scanning Calorimetry (DSC) that gas hydrate formation and dissociation has a destabilizing effect on W/O emulsions, and can even lead to a free water phase through agglomeration and coalescence of dissociated hydrate particles. Gas hydrate formation/dissociation has been shown to cause rapid hydrate agglomeration and emulsion destabilization. High asphaltene content crude oils are shown to resist hydrate destabilization of the emulsion.

description: We consider the algebra of N x N matrices as a reduced quantum plane on which a finite-dimensional quantum group H acts. This quantum group is a quotient of U_q(sl(2,C)), q being an N-th root of unity. Most of the time we shall take N=3; in that case \dim(H) = 27. We recall the properties of this action and introduce a differential calculus for this algebra: it is a quotient of the Wess-Zumino complex. The quantum group H also acts on the corresponding differential algebra and we study its decomposition in terms of the representation theory of H. We also investigate the properties of connections, in the sense of non commutative geometry, that are taken as 1-forms belonging to this differential algebra. By tensoring this differential calculus with usual forms over space-time, one can construct generalized connections with covariance properties with respect to the usual Lorentz group and with respect to a finite-dimensional quantum group.

description: In the type II diabetes mellitus, Metformin hydrochloride is recommended as a common FAD approved drug. Synthesis of novel metformin series has been widely explored, mainly due to its biological importance and to improve their pharmacokinetic profile. Generally, human serum albumin (HSA) is the main protein used to study drug viability in vitro analysis. Thus, the present study reports the synthesis of three new halogenated metformin derivatives (MFCl, MFBr and MFCF3) and its interaction toward HSA by multiple spectroscopic techniques (UV-Vis, circular dichroism, steady-state, time-resolved and synchronous fluorescence), combined to computational methods (molecular docking and quantum chemical calculation). The interaction between each halogenated metformin derivative and HSA is spontaneous (ΔG°<0), entropically driven (ΔS°>0), moderate (Ka and Kb ≈ 104 M−1) and occurs preferentially in the subdomain IIA (close to Trp-214 residue). Molecular docking results suggested hydrogen bonding, van der Waals and hydrophobic interactions as the main binding forces. Quantum chemical calculations suggested imino groups as the most intense electrostatic negative potentials, while the positive electrostatic potential is located at the hydrogen atoms on N,N-dimethyl and the phenyl systems which can help the hydrophobic interactions.

Hemiscylliidae

description: Family Hemiscylliidae   Bamboo sharks are poorly studied in the Bangladesh region, though a total of five species have been recorded; Chiloscyllium burmensis, C. griseum, C. indicum and C. punctatum (Hoq et al. 2011; Haque et al. 2019a) and most recently C. hasseltii (Datta et al. 2020). In this study, a total of 129 specimens of Chiloscyllium hasseltii (Figure 16) were morphologically identified. Eleven specimens that appeared morphologically consistent with Chiloscyllium arabicum (Figure 17) were also recorded, but in the absence of genetic data this warrants further investigation.

description: The Leighton group has long been interested in developing strained silanes for their use in polyketide synthesis. Recently, our interests have led us to develop a new type of silicon Lewis acid and catalyst with high levels of reactivity. Upon activation with a thiourea, a stabilized silylium ion is formed allowing for the facile allylation of aldehydes and ketones, in addition to Diels-Alder catalysis. This represents one of the first examples of the merger between anion-binding catalysis and silylium ion catalysis. Our group’s interest in strained silanes has also led us to investigate their conductance properties in molecular break junctions. To further understand the nature of the bond-ruptured species we have proposed new synthetic targets and have described herein our progress towards synthesizing these targets.

description: In contrast to the usual Lipschitz seminorms associated to ordinary metrics on compact spaces, we show by examples that Lipschitz seminorms on possibly non-commutative compact spaces are usually not determined by the restriction of the metric they define on the state space, to the extreme points of the state space. We characterize the Lipschitz norms which are determined by their metric on the whole state space as being those which are lower semicontinuous. We show that their domain of Lipschitz elements can be enlarged so as to form a dual Banach space, which generalizes the situation for ordinary Lipschitz seminorms. We give a characterization of the metrics on state spaces which come from Lipschitz seminorms. The natural (broader) setting for these results is provided by the ``function spaces'' of Kadison. A variety of methods for constructing Lipschitz seminorms is indicated.

description: Photocatalysis is a robust synthetic tool capable of breaking and assembling chemical bonds using single electron chemistry. This is achieved through the catalytic conversion of light energy to chemical energy in situ, such that the photons being delivered are themselves reagents. Herein, an inexpensive and environmentally-benign platform for scaling up photocatalytic reaction is disclosed, harnessing blue light naturally emitted by deep-sea bioluminescent bacteria. Photobacterium angustum GB-1 was demonstrated to photoexcite both polypyridyl organometallic chromophores and organic dyes at short molecular distances, enabling photocatalysis without any external energy-consuming lamps.While improving the eco-friendliness of photocatalysis itself, we also present a method to use photocatalysis for environmental remediation. Using visible light, a nontoxic organic photosensitizer, and oxygen, we demonstrate the controlled oxidative depolymerization of polystyrene—including polystyrene retrieved from waste receptacles in Havemeyer—to acetophenone. This method is based on results obtained in the controlled aerobic deannulation of cycloalkanes, which is also discussed herein. Lastly, a means by which catalysis itself can be made more cost, resource, and time effective is presented. An innovative computational platform in development predicts new catalysts for reactions currently energetically inaccessible. In collaboration with the developers, we present experimental validation of their theoretical predictions, as well as perform the synthesis of a de novo fluorinated thiazolium precatalyst calculated to significantly lower the energetic barrier of an otherwise energetically prohibitive Stetter reaction.

description: Boana atlantica was described based on morphological characters to acommodate populations from Bahia state, Brazil, previously referred to as B. punctata. However, its taxonomic validity is questionable due to inconsistencies in bioacoustic data. Here, we integrate molecular, cytogenetic and morphological data to re-evaluate the taxonomic status of B. atlantica. Molecular analyses provided strong support for the hypothesis that B. atlantica is a valid species, being, however, nominal populations from Bahia state paraphyletic with respect to individuals of B. atlantica collected in Alagoas and Pernambuco states. These populations shown high genetic divergence in the 16S rRNA mitochondrial fragment, and we consider populations from Alagoas and Pernambuco as a putative new candidate species of Boana punctata group. The external and internal morphology of the tadpoles of these lineages were similar, but Nucleolar Organizer Regions (NOR) was sited in different chromosomes. Our results indicate that B. atlantica is paraphyletic and may be a complex of species. Morphological of adult and/or bioacoustical data should be further assessed to find diagnostic characters to tease these lineages apart and name them properly.

description: Family Triakidae   Three houndshark species have been previously recorded from Bangladesh, i.e. Mustelus manazo, M. mosis and Iago garricki (Hoq et al. 2011; Habib et al. 2020).A total of 31 specimens of a second species of the Iago omanensis complex (which includes the poorly defined I. mangalorensis, if considered valid (Sen et al. 2020; Weigmann 2016; Maduna & Bester-van der Merwe 2017)) were recorded in this study. There is a possibility the recorded Iago sp. could be a new species to science as two separate species (Iago sp. A and Iago sp. B) have been theorised to be present in the Indian waters (Bineesh et al. 2017). This species is tentatively identified as Iago cf. omanensis (Figure 18) pending further taxonomic investigation. It brings the total number of triakid species in Bangladesh to four, with the taxonomy of the Mustelus species in this region being investigated by one of the authors (WW).

description: Spin dephasing via the spin-orbit interaction (SOI) is a major mechanism limiting the electron spin lifetime in III-V zincblende quantum wells. The dephasing can be suppressed in GaAs(111) quantum wells by applying an electric field. The suppression has been attributed to the compensation of the intrinsic SOI associated by the bulk inversion asymmetry (BIA) of the GaAs lattice by a structural induced asymmetry (SIA) SOI term induced by an electric field. We provide direct experimental evidence for this mechanism by demonstrating the transition between the BIA-dominated to a SIA-dominated regime via photoluminescence measurements carried out over a wide range of applied fields. Spin lifetimes exceeding 100~ns are obtained near the compensating electric field, thus making GaAs (111) QWs excellent candidates for the electrical storage and manipulation of spins.
