description: The concept of synthetic dimensions in photonics provides a versatile platform in exploring multi-dimensional physics. Many of these physics are characterized by band structures in more than one dimensions. Existing efforts on band structure measurements in the photonic synthetic frequency dimension however are limited to either one-dimensional Brillouin zones or one-dimensional subsets of multi-dimensional Brillouin zones. Here we theoretically propose and experimentally demonstrate a method to fully measure multi-dimensional band structures in the synthetic frequency dimension. We use a single photonic resonator under dynamical modulation to create a multi-dimensional synthetic frequency lattice. We show that the band structure of such a lattice over the entire multi-dimensional Brillouin zone can be measured by introducing a gauge potential into the lattice Hamiltonian. Using this method, we perform experimental measurements of two-dimensional band structures of a Hermitian and a non-Hermitian Hamiltonian. The measurements reveal some of the general properties of point-gap topology of the non-Hermitian Hamiltonian in more than one dimensions. Our results demonstrate experimental capabilities to fully characterize high-dimensional physical phenomena in the photonic synthetic frequency dimension.

description: Background:  Obsessive compulsive symptoms are becoming more common in children and adolescents, according to mental health practitioners. Our epidemiology study intends to estimate the prevalence of obsessive symptoms and obsessive compulsive disorder among secondary school students, as well as examine religious attitudes among those patients as a secondary research target. Materials: The study is cross-sectional and was conducted on 1299 secondary school students, with an adequate sample size estimated based on a literature prevalence of 2% for Obsessive Compulsive Disorder (OCD). Equal samples were taken from each of Alexandria Governorate's three educational zones. Obsessive compulsive symptoms were assessed by the Lyeton obsessive inventory child LOI-CV, the Arabic version that has been validated and tested for reliability in Egyptian culture. Those scoring 35 or above were subjected to the Mini International Neuropsychiatric Interview for children MINI-KID Arabic. Patients with OCD had their diagnosis confirmed through a psychiatric interview to ensure that they met the DSM IV –TR criteria for OCD. Religious attitudes were assessed using a validated self-reporting questionnaire. Results: Among the studied sample (n=1299), 201 students were scored > 35 on LOI-CV i.e. 15.5% of the total sample have OCS The prevalence of OCD among studied sample was 2.2% as 29 students from the OCS students were fulfilling diagnostic criteria for OCD according to DSM-IV TR. Adolescents with obsessive compulsive disorder OCD and obsessive compulsive symptoms OCS had religious practising attitudes of 93.1% and 79.6%, respectively, with no difference (X2=0.07). Conclusion: Obsessive symptoms are very prevalent among adolescents; this observation emphasises the importance of public awareness and screening of adolescents for early detection and management. The religious attitudes of teenagers with either obsessive compulsive disorder or merely obsessive compulsive symptoms did not differ significantly. Obsessions and compulsions' phenomenology, rather than their prevalence in the population, may be influenced by religious order and upbringing.

description: In this work, we make use of a supervised machine learning algorithm based on Logistic Regression (LR) to select TeV blazar candidates from the 4FGL-DR2 / 4LAC-DR2, 3FHL, 3HSP, and 2BIGB catalogs. LR constructs a hyperplane based on a selection of optimal parameters, named features, and hyper-parameters whose values control the learning process and determine the values of features that a learning algorithm ends up learning, to discriminate TeV blazars from non-TeV blazars. In addition, it gives the probability (or logistic) that a source may be considered as a TeV blazar candidate. Non-TeV blazars with logistics greater than 80% are considered high-confidence TeV candidates. Using this technique, we identify 40 high-confidence TeV candidates from the 4FGL-DR2 / 4LAC-DR2 blazars and we build the feature hyper-plane to distinguish TeV and non-TeV blazars. We also calculate the hyper-planes for the 3FHL, 3HSP, and 2BIGB. Finally, we construct the broadband spectral energy distributions (SED) for the 40 candidates, testing for their detectability with various instruments. We find that 7 of them are likely to be detected by existing or upcoming IACT observatories, while 1 could be observed with EAS particle detector arrays.

description: Results from Juno's microwave radiometer indicate non-uniform mixing of ammonia vapor in Jupiter's atmosphere down to tens of bars, far beneath the cloud level. Helioseismic observations suggest solar convection may require narrow, concentrated downdrafts called entropy rain to accommodate the Sun's luminosity. Both observations suggest some mechanism of non-local convective transport. We seek to predict the depth that a concentrated density anomaly can reach before efficiently mixing with its environment in bottomless atmospheres. We modify classic self-similar analytical models of entraining thermals to account for the compressibility of an abyssal atmosphere. We compare these models to the output of high resolution three dimensional fluid dynamical simulations to more accurately model the chaotic influence of turbulence. We find that localized density anomalies propagate down to ~3-8 times their initial size without substantially mixing with their environment. Our analytic model accurately predicts the initial flow, but the self-similarity assumption breaks down after the flow becomes unstable at a characteristic penetration depth. In the context of Jupiter, our findings suggest that precipitation concentrated into localized downdrafts of size ~20km can coherently penetrate to on the order of a hundred kilometers (tens of bars) beneath its initial vaporization level without mixing with its environment. This finding is consistent with expected convective storm length-scales, and Juno MWR measurements of ammonia depletion. Compositional gradients of volatiles beneath their cloud levels may be common on stormy giant planets. In the context of the Sun, we find that turbulent downdrafts in abyssal atmospheres cannot maintain their coherence through the Sun's convective layer, a potential challenge for the entropy rain hypothesis.

description: Der Artikel liefert einen vollständigen Katalog der thrakischen Panzer und »Mitren«. Er nimmt sowohl die Typologie und Herstellung als auch die Verteilung und die soziale Funktion dieser Schutzwaffen in den Blick. Die Grundlage hierfür bildete die Arbeit von L. Ognenova; ihre Beobachtungen wurden mit den archäologischen Daten in einem aktuellen Katalog verglichen. Gleichzeitig wurde das thrakische Inventar dem griechischen gegenübergestellt, um das Verhältnis zueinander und eine Abhängigkeit oder Unabhängigkeit voneinaner zu diskutieren. Leider macht es die Bruchstückhaftigkeit (oder gar das Fehlen) der Dokumentation zu den meisten archäologischen Fundkontexten notwendig, auf die Entdeckung neuer Befunde zu warten, um die Beobachtungen dieser Studie zu bestätigen. Der Artikel behandelt vier Themen: Klassifizierung der Panzer in drei Gruppen; Bestimmung ihrer Chronologie innerhalb des 5. Jahrhunderts v. Chr.; Bestätigung, dass es ausschließlich thrakische Produkte und keine griechischen Importe sind; und schließlich die Feststellung, dass diese Stücke mehr der sozialen Zurschaustellung als der militärischen Verwendung oder im Zweikampf dienten, was in jedem Fall keinen Bezug zur Reiterei hat, schon aus ergonomischen und technischen Gründen. Um diesen neuen Aspekt zu erklären, schlage ich vor, dass die Notwendigkeit sozialer Selbstbestätigung die Herstellung dieser »Schmuckstücke« später angeregt wurde als ihre Verwendung im archaischen Griechenland, in deren Sozialstruktur sie nicht mehr gebraucht wurden. Alle beobachteten Charakteristika (Typologie, Chronologie, soziale Verwendung) geben dem Phänomen der thrakischen Schutzwaffen eine erkennbare eigene Identität, einerseits durch ihre räumliche Konzentration und andererseits durch ihren Erfolg quer durch die Eliten der thrakischen Kultur.

Reclaiming the gaze : examining contemporary Nuxalk perspectives on Harlan I. Smith's fieldwork photographs, 1920-1924

description: Archival photographs of native peoples are tricky objects. They complicate the current rhetoric of repatriation and collaboration that tends to dominate present reassertions of control by First Nations communities over objects held (or once held) by non-native institutions. Framing the reclamation of cultural objects by First Nations peoples from non-native museums as acts of repatriation does not address instances in which little or no dialogue or collaboration exists - the instances when native peoples enter (or break into) the museum or archive through other means. The perspectives of contemporary Nuxalkmc on and employments of Harlan Smith’s photographs discussed here emerge from larger processes of self-determination and identity-making. I argue that this represents an important way in which contemporary Nuxalkmc assert a form of possession of these photographs, reclaiming and repurposing them in ways that have produced a space for these images outside of the museum archive, on their own terms.

description: Superconducting nanowire single photon detectors (SNSPDs) are the highest-performing technology for time-resolved single-photon counting from the UV to the near-infrared. The recent discovery of single-photon sensitivity in micrometer-scale superconducting wires is a promising pathway to explore for large active area devices with application to dark matter searches and fundamental physics experiments. We present 8-pixel $1 mm^2$ superconducting microwire single photon detectors (SMSPDs) with $1\,\mathrm{μm}$-wide wires fabricated from WSi and MoSi films of various stoichiometries using electron-beam and optical lithography. Devices made from all materials and fabrication techniques show saturated internal detection efficiency at 1064 nm in at least one pixel, and the best performing device made from silicon-rich WSi shows single-photon sensitivity in all 8 pixels and saturated internal detection efficiency in 6/8 pixels. This detector is the largest reported active-area SMSPD or SNSPD with near-IR sensitivity published to date, and the first report of an SMSPD array. By further optimizing the photolithography techniques presented in this work, a viable pathway exists to realize larger devices with $cm^2$-scale active area and beyond.

description: A typical web search engine consists of three principal parts: crawling engine, indexing engine, and searching engine. The present work aims to optimize the performance of the crawling engine. The crawling engine finds new web pages and updates web pages existing in the database of the web search engine. The crawling engine has several robots collecting information from the Internet. We first calculate various performance measures of the system (e.g., probability of arbitrary page loss due to the buffer overflow, probability of starvation of the system, the average time waiting in the buffer). Intuitively, we would like to avoid system starvation and at the same time to minimize the information loss. We formulate the problem as a multi-criteria optimization problem and attributing a weight to each criterion. We solve it in the class of threshold policies. We consider a very general web page arrival process modeled by Batch Marked Markov Arrival Process and a very general service time modeled by Phase-type distribution. The model has been applied to the performance evaluation and optimization of the crawler designed by INRIA Maestro team in the framework of the RIAM INRIA-Canon research project.

description: We have started a systematic survey of molecular clumps with infall motions to study the very early phase of star formation. Our first step is to utilize the data products by MWISP to make an unbiased survey for blue asymmetric line profiles of CO isotopical molecules. Within a total area of $\sim$ 2400 square degrees nearby the Galactic plane, we have found 3533 candidates showing blue-profiles, in which 3329 are selected from the $^{12}$CO&$^{13}$CO pair and 204 are from the $^{13}$CO&C$^{18}$O pair. Exploration of the parametric spaces suggests our samples are in the cold phase with relatively high column densities ready for star formation. Analysis of the spatial distribution of our samples suggests that they exist virtually in all major components of the Galaxy. The vertical distribution suggest that the sources are located mainly in the thick disk of $\sim$ 85 parsec, but still a small part are located far beyond Galactic midplane. Our follow-up observation indicates that these candidates are a good sample to start a search for infall motions, and to study the condition of very early phase of star formation.

description: In the late sixteenth century, the French provincial lawyer Jean I du Temps of Blois (fl. 1570s–1590s) devoted countless hours to difficult forms of scholarship that wove together the cultures of letters and mathematics. Perhaps the most astounding product of his labour is a manuscript set of instruments for calculating the locations of the heavenly bodies: Organon astronomicon ex hypothesibus Copernici extructum (Astronomical instrument constructed from the hypotheses of Copernicus). Unusually, and as its title indicates, the work is based on the calculations that underpin Nicolaus Copernicus’ proposition of a heliocentric world system, published in his De revolutionibus (1543). This, as we shall suggest, bears on the manuscript’s distinctive aesthetic, whereby the data on which Copernicus’ provocative hypotheses rest are rendered both delightful and useful. In making his Organon, du Temps deployed cunning visual tactics to engage the reader, guiding them towards an appreciation both of the heavens’ mathematically ordered beauty and of his own ingenium.

description: Magnetic fields appear to be ubiquitous in astrophysical environments. Their existence in the intracluster medium is established through observations of synchrotron emission and Faraday rotation. On the other hand, the nature of magnetic fields outside of clusters, where observations are scarce and controversial, remains largely unknown. In this chapter, we review recent developments in our understanding of the nature and origin of intergalactic magnetic fields, and in particular, intercluster fields. A plausible scenario for the origin of galactic and intergalactic magnetic fields is for seed fields, created in the early universe, to be amplified by turbulent flows induced during the formation of the large scale structure. We present several mechanisms for the generation of seed fields both before and after recombination. We then discuss the evolution and role of magnetic fields during the formation of the first starts. We describe the turbulent amplification of seed fields during the formation of large scale structure and the nature of the magnetic fields that arise. Finally, we discuss implications of intergalactic magnetic fields.

The Envious Destroyer of All Things

description: Time, which kills everything, obsessed early modern England’s architects as much as its playwrights. If for a distraught Macbeth, moments crept interminably, for Stuart and Tudor builders, time’s slog always threatened to end too soon. The inevitability of architectural death through slow ruin, or frenetic dismantling, took on particular verve in a polity with a history of iconoclasm. Architecture’s emphasis upon surface aligned building with (say) portraiture which, around 1600, carried its own rhetorics of time – and information – arrested. Both building and posing subsisted in the proffering of a good face, the warding off of bodily death. And in the case of this article’s focus – an ephemeral arch built in London in 1603 – this face – this façade – was threatened by unexpected epistemes of time: duration, instant, and epoch. These were temporalities in upheaval in Stuart London, a moment of unsteady power relations, of new kinds of printed publications, and of that most unpresentable of human phenomena: contagion.

description: The electronic spectroscopy of four anions (SSNSS–, SSNS–, SSNO–, SNO–) was studied using Time-Dependent Density Functional Theory (TD-DFT), Equation Of Motion Coupled Cluster with Singles and Doubles (EOM-CCSD) and the Completely Renormalised Equation-Of- Motion with Singles, Doubles and non-iterative Triples (CR-EOM-CCSD(T)) methods. The same methodology was applied to check the electronic spectroscopy of different anions whose structure or even existence are not well stated (SNS–, SSN–, SSNSO–, SNO2−). The agreement of the calculated bands in UV-vis for these compounds with the experimental bands of UV-vis for SSN– and SSNSO– makes it very likely that these molecules were the intermediate ones that absorb strongly in the UV-vis. On the contrary, the fact that SNO2− was an anion that absorbs strongly in the visible spectrum in certain reactions looks doubtful.
Reduced attentional capture in action video game players

Publisher: name: University of British Columbia

description: Over the past 30 years, video games have become a more accepted and increasingly popular form of entertainment. Due to this increase in public interest as well as the increasing complexity of modern video games, researchers have begun to study whether extensive video game experience can affect cognitive and perceptual skills. Of particular interest is whether video game experience affects aspects of visual attention. Recent studies indicate that playing action video games improves performance on a number of visual attention-based tasks. However, it remains unclear whether action video game experience primarily affects endogenous or exogenous forms of spatial orienting. To examine this issue, action video game players and non-action video game players performed an attentional capture task. Results showed that action video game players responded quicker than non-action video game players both when a target appeared in isolation and when a salient, task-irrelevant distractor was present in the display. Action video game players additionally showed a smaller capture effect than non-action video game players. When coupled with the findings of previous studies, the collective evidence indicates that extensive experience with action video games may enhance players’ top-down attentional control which in turn can modulate the negative effects of bottom-up attentional capture. Collectively, this work also adds to the literature suggesting that video games can provide a novel form of rehabilitation for individuals living with various cognitive or visual deficits.

description: Herbig Ae/Be stars are intermediate-mass pre-main sequence stars undergoing accretion through their circumstellar disk. The optical and infrared (IR) spectra of HAeBe stars show HI emission lines belonging to Balmer, Paschen and Brackett series. We use the archival X-Shooter spectra available for 109 HAeBe stars from Vioque et al. (2018) and analyse the various HI lines present in them. We segregated the stars into different classes based on the presence of higher-order lines in different HI series. We discuss the dependence of the appearance of higher-order lines on the stellar parameters. We find that most massive and younger stars show all the higher-order lines in emission. The stars showing only lower-order lines have Teff < 12000 K and an age range of 5-10 Myr. We perform a Case B line ratio analysis for a sub-sample of stars showing most of the HI lines in emission. We note that all but four stars belonging to the sub-sample show lower HI line ratios than theoretical values, owing to the emitting medium being optically thick. The HI line flux ratios do not depend on the star's spectral type. Further, from the line ratios of lower-order lines and Paschen higher-order lines, we note that line ratios of most HAeBe stars match with electron density value in the range 10^9 - 10^11 cm^-3. The electron temperature, however, could not be ascertained with confidence using the line ratios studied in this work.

description: We present spectro-polarimetric observations of several molecular lines obtained with the Submillimeter Array (SMA) toward the carbon rich AGB star IRC+10216. We have detected and mapped the linear polarization of the CO 3-2, SiS 19-18 and CS 7-6 lines. The polarization arises at a distance of ~450 AU from the star and is blueshifted with respect the Stokes I. The SiS 19-18 polarization pattern appears to be consistent with a locally radial magnetic field configuration. However, the CO 3-2 and CS 7-6 line polarization suggests an overall complex magnetic field morphology within the envelope. This work demonstrates the feasibility of using spectro-polarimetric observations to carry out tomographic imaging of the magnetic field in circumstellar envelopes.

description: The stellar companion to the weak-line T Tauri star DI Tau A was first discovered by the lunar occultation technique in 1989 and was subsequently confirmed by a speckle imaging observation in 1991. It has not been detected since, despite being targeted by five different studies that used a variety of methods and spanned more than 20 years. Here, we report the serendipitous rediscovery of DI Tau B during our Young Exoplanets Spectroscopic Survey (YESS). Using radial velocity data from YESS spanning 17 years, new adaptive optics observations from Keck II, and a variety of other data from the literature, we derive a preliminary orbital solution for the system that effectively explains the detection and (almost all of the) non-detection history of DI Tau B. We estimate the dynamical masses of both components, finding that the large mass difference (q $\sim$0.17) and long orbital period ($\gtrsim$35 years) make DI Tau system a noteworthy and valuable addition to studies of stellar evolution and pre-main-sequence models. With a long orbital period and a small flux ratio (f2/f1) between DI Tau A and B, additional measurements are needed for a better comparison between these observational results and pre-main-sequence models. Finally, we report an average surface magnetic field strength ($\bar B$) for DI Tau A, of $\sim$0.55 kG, which is unusually low in the context of young active stars.

description: We present a high-speed wavelength tunable photonic crystal fiber-based source capable of generating tunable femtosecond solitons in the infrared region. Through measurements and numerical simulation, we show that both the pulsewidth and the spectral width of the output pulses remain nearly constant over the entire tuning range from 860 to 1160 nm. This remarkable behavior is observed even when pump pulses are heavily chirped (7400 fs^2), which allows to avoid bulky compensation optics, or the use of another fiber, for dispersion compensation usually required by the tuning device.

description: Atomic beams are a longstanding technology for atom-based sensors and clocks with widespread use in commercial frequency standards. Here, we report the demonstration a chip-scale microwave atomic beam clock using coherent population trapping (CPT) interrogation in a passively pumped atomic beam device. The beam device consists of a hermetically sealed vacuum cell fabricated from an anodically bonded stack of glass and Si wafers. Atomic beams are created using a lithographically defined microcapillary array connected to a Rb reservoir1 and propagate in a 15 mm long drift cavity. We present a detailed characterization of the atomic beam performance (total Rb flux $\approx 7.7 \times 10^{11} s^{-1}$ at 363 K device temperature) and of the vacuum environment in the device (pressure < 1 Pa), which is sustained using getter materials which pump residual gases and Rb vapor. A chip-scale beam clock is realized using Ramsey CPT spectroscopy of the 87Rb ground state hyperfine transition over a 10 mm Ramsey distance in the atomic beam device. The prototype atomic beam clock demonstrates a fractional frequency stability of $\approx 1.2 \times 10^{-9}/\sqrtτ$ for integration times $τ$ from 1 s to 250 s, limited by detection noise. Optimized atomic beam clocks based on this approach may exceed the long-term stability of existing chip-scale clocks, and leading long-term systematics are predicted to limit the ultimate fractional frequency stability below $10^{-12}$.

description: The paper presents a quality of service aware routing protocol which provides low latency for high priority packets. Packets are differentiated based on their priority by applying queuing theory. Low priority packets are transferred through less energy paths. The sensor nodes interact with the pivot nodes which in turn communicate with the sink node. This protocol can be applied in monitoring context aware physical environments for critical applications.

description: During the reign of Thutmose III, as a result of the military campaigns and of the increased importance of the army as a branch of the royal government in ancient Egypt, there was a growing tendency to favour some military officials with political and administrative positions. In this context, the aim of this paper is to analyse the Egyptian officials bearing the title of ‘governor’ or ‘mayor’ during this reign and the articulation of local powers with the king and his retinue. I discuss briefly some of the questions related to the study of regional administration and I intend to determine to what extent it is possible to identify this pattern of favour in administrative positions related to the provinces, also considering how these officials were connected with the king and his entourage.

description: Mid-infrared observations are powerful in identifying heavily obscured Active Galactic Nuclei (AGN) which have weak emission in other wavelengths. Data from the Mid-Infrared Instrument (MIRI) onboard JWST provides an excellent opportunity to perform such studies. We take advantage of the MIRI imaging data from the Cosmic Evolution Early Release Science Survey (CEERS) to investigate the AGN population in the distant universe. We estimate the source properties of MIRI-selected objects by utilizing spectral energy distribution (SED) modelling, and classify them into star-forming galaxies (SF), SF-AGN mixed objects, and AGN. The source numbers of these types are 418, 111, and 31, respectively, from 4 MIRI pointings covering $\sim 9$ arcmin$^2$. The sample spans a redshift range of $\approx 0$--5. We derive the median SEDs for all three source types, respectively, and publicly release them. The median MIRI SED of AGN is similar to the typical SEDs of hot dust-obscured galaxies and Seyfert 2s, for which the mid-IR SEDs are dominantly from AGN-heated hot dust. Based on our SED-fit results, we estimate the black-hole accretion density (BHAD; i.e., total BH growth rate per comoving volume) as a function of redshift. At $z<3$, the resulting BHAD agrees with the X-ray measurements in general. At $z>3$, we identify a total of 27 AGN and SF-AGN mixed objects, leading to that our high-$z$ BHAD is substantially higher than the X-ray results ($\sim 0.5$ dex at $z \approx 3$--5). This difference indicates MIRI can identify a large population of heavily obscured AGN missed by X-ray surveys at high redshifts.

Ion pump activity generates fluctuating electrostatic forces in biomembranes

description: We study the non-equilibrium dynamics of lipid membranes with proteins that actively pump ions across the membrane. We find that the activity leads to a fluctuating force distribution due to electrostatic interactions arising from variation in dielectric constant across the membrane. By applying a multipole expansion we find effects on both the tension and bending rigidity dominated parts of the membranes fluctuation spectrum. We discuss how our model compares with previous studies of force-multipole models.

description: $\require{mediawiki-texvc}$ We study accretion disk emission from eight Seyfert $1 - 1.5$ active galactic nuclei (AGN) using far ultra-violet ($1300-1800$ $Å$) slit-less grating spectra acquired with AstroSat/UVIT. We correct for the Galactic and intrinsic extinction, contamination from the host galaxies, narrow and broad-line regions, Fe II emission and Balmer continuum, and derive the intrinsic continua. We use HST COS/FOS spectra to account for the emission/absorption lines in the low-resolution UVIT spectra. We find generally redder power-law ($f_ν\propto ν^α$) slopes ($α\sim -1.1 - 0.3$) in the far UV band than predicted by the standard accretion disk model in the optical/UV band. We fit accretion disk models such as the multi-temperature disk blackbody ($\texttt{DISKBB}$) and relativistic disk ($\texttt{ZKERRBB}$, $\texttt{OPTXAGNF}$) models to the observed intrinsic continuum emission. We measure the inner disk temperatures using the $\texttt{DISKBB}$ model for seven AGN. These temperatures in the range $\sim 3.6-5.8$ eV are lower than the peak temperatures predicted for standard disks around maximally spinning super-massive black holes accreting at Eddington rates. The inner disks in two AGN, NGC 7469 and Mrk 352, appear to be truncated at $\sim 35-125r_{g}$ and $50-135r_{g}$, respectively. While our results show that the intrinsic FUV emission from the AGN are consistent with the standard disks, it is possible that UV continua may be affected by the presence of soft X-ray excess emission, X-ray reprocessing, and thermal Comptonisation in the hot corona. Joint spectral modeling of simultaneously acquired UV/X-ray data may be necessary to further investigate the nature of accretion disks in AGN.

description: Vibrio cholerae causes life-threatening infections in low-income countries due to the rise of antibacterial resistance. Innovative pharmacological targets have been investigated and carbonic anhydrases (CAs, EC: 4.2.1.1) encoded by V. cholerae (VchCAs) emerged as a valuable option. Recently, we developed a large library of para- and meta-benzenesulfonamides characterised by moieties with a different flexibility degree as CAs inhibitors. Stopped flow-based enzymatic assays showed strong inhibition of VchαCA for this library, while lower affinity was detected against the other isoforms. In particular, cyclic urea 9c emerged for a nanomolar inhibition of VchαCA (KI = 4.7 nM) and high selectivity with respect to human isoenzymes (SI≥ 90). Computational studies revealed the influence of moiety flexibility on inhibitory activity and isoform selectivity and allowed accurate SARs. However, although VchCAs are involved in the bacterium virulence and not in its survival, we evaluated the antibacterial activity of such compounds, resulting in no direct activity.

description: In this paper, we extend our previous analysis concerning the formation of inhomogeneous condensates in strongly-coupled fermion effective field theories on curved spaces and include the case of conifold geometries that represent the simplest tractable case of manifolds with curvature singularities. In the set-up considered here, by keeping the genuine thermodynamical temperature constant, we may single out the role that curvature effects play on the breaking/restoration of chiral symmetry and on the appearance of inhomogeneous phases. The first goal of this paper is to construct a general expression of the finite temperature effective action for inhomogeneous condensates in the case of four-fermion effective field theories on conifold geometries with generic Riemannian smooth base (generalised cones). The other goal is to implement numerically the above formal results and construct self-consistent solutions for the condensate. We explicitly show that the condensate assumes a kink-like profile, vanishing at the singularity that is surrounded by a bubble of restored chiral symmetry phase.
