description: The coordination behavior of the tridentate alkoxy ligand 6,6'-(((2-hydroxyethyl)azanediyl)bis(methylene)) bis(2,4-di-tert-butylphenol) (termed H3-AM-DBP2) with group 4 metal alkoxides ([M(OR)4]) in a 1:1 ratio was previously found to generate [(ONep)Ti(κ 4 (O,O’,O”,N)-AM-DBP2)] and [(OR)Zr(κ 4 (μ-O,O’,O”,N)-AM-DBP2)]2 (M = Zr, Hf). Additional studies revealed that increasing the stoichiometric ratio to 1:2 H3-AM-DBP2:[M(OR)4] led to the isolation of [(ONep)Ti(κ 4 (μ-O,O’,O”,N)-AM-DBP2)(μ-ONep)Ti(ONep)3] (1)•tol, [(OBu t)Zr(κ 4 (μ-O,O’,O”,N)-AM-DBP2)(μ-OBu t)Zr(OBu t)3] (2) and [(OBu t)Hf(κ 4 (μ-O,O’,O”,N)-AM-DBP2)(μ-OBu t)Hf(OBu t)3] (3). The asymmetric dinuclear complexes of 1-3 resemble the chelation of a [M(OR)4] moiety to a “(OR)M(κ 4 (O,O’,O”,N)-AM-DBP2)” fragment. The metal complexed by the AM-DBP2 ligand has a pseudo octahedral geometry while the other metal adopts an intermediate trigonal bipyramidal (TBP-5)/square base pyramidal (SBP-5) geometry for 1 but a distorted SBP-5 for both 2 and 3. The structure and properties of 1-3 were analyzed by computational modeling and fully characterized by standard analytical methods.

description: Trifluoromethoxylated (hetero)arenes are of great interest for several disciplines, especially in agro- and medicinal chemistry. Radical C−H trifluoromethoxylation of (hetero)arenes represents an attractive approach to prepare such compounds, but the high cost and low atom economy of existing .OCF3 radical sources make them unsuitable for the large-scale synthesis of trifluoromethoxylated building blocks. Herein, we introduce bis(trifluoromethyl)peroxide (BTMP, CF3OOCF3) as a practical and efficient trifluoromethoxylating reagent that is easily accessible from inexpensive bulk chemicals. Using either visible light photoredox or TEMPO catalysis, trifluoromethoxylated arenes could be prepared in good yields under mild conditions directly from unactivated aromatics. Moreover, TEMPO catalysis allowed for the one-step synthesis of valuable pyridine derivatives, which have been previously prepared via multi-step approaches.

description: We study conformally-invariant theories of gravity in six dimensions. In four dimensions, there is a unique such theory that is polynomial in the curvature and its derivatives, namely Weyl-squared, and furthermore all solutions of Einstein gravity are also solutions of the conformal theory. By contrast, in six dimensions there are three independent conformally-invariant polynomial terms one could consider. There is a unique linear combination (up to overall scale) for which Einstein metrics are also solutions, and this specific theory forms the focus of our attention in this paper. We reduce the equations of motion for the most general spherically-symmetric black hole to a single 5th-order differential equation. We obtain the general solution in the form of an infinite series, characterised by 5 independent parameters, and we show how a finite 3-parameter truncation reduces to the already known Schwarzschild-AdS metric and its conformal scaling. We derive general results for the thermodynamics and the first law for the full 5-parameter solutions. We also investigate solutions in extended theories coupled to conformally-invariant matter, and in addition we derive some general results for conserved charges in cubic-curvature theories in arbitrary dimensions.

description: We bring the EKRT framework, which combines perturbative QCD (pQCD) minijet production with gluon saturation and hydrodynamics, to next-to-leading order (NLO) in pQCD as rigorously as possible. We chart the model uncertainties, and study the viability and predictive power of the model in the light of the RHIC and LHC measurements in central $A+A$ collisions. In particular, we introduce a new set of measurement functions to define the infrared- and collinear-safe minijet transverse energy, $E_T$, in terms of which we formulate the saturation. We update the framework with the EPS09 NLO nuclear parton distributions (nPDFs), and study the propagation of the nPDF uncertainties into the computed $E_T$, saturation scales and the final-state multiplicities. The key parameters, which need to be fixed using the measurements, are identified, and their correlation is discussed. We convert the saturated minijet $E_T$ into QCD-matter initial conditions for longitudinally boost-invariant ideal hydrodynamics. We compute the charged-particle multiplicities and identified bulk hadron $p_T$ spectra in 5% most central Au+Au collisions at RHIC and Pb+Pb at the LHC. We obtain an encouragingly good agreement with the experimental data, simultaneously at RHIC and LHC, showing that the approach has a definite predictive power.

description: We consider the structure and physical properties of specific classes of neutron, quark and "exoti"' stars in Eddington-inspired Born-Infeld (EiBI) gravity. The latter reduces to standard general relativity in vacuum, but presents a different behavior of the gravitational field in the presence of matter. The equilibrium equations for a spherically symmetric configuration (mass continuity and Tolman-Oppenheimer-Volkoff) are derived, and their solutions are obtained numerically for different equations of state of neutron and quark matter. More specifically, stellar models, described by the stiff fluid, radiation-like, polytropic and the bag model quark equations of state are explicitly constructed in both general relativity and EiBI gravity, thus allowing a comparison between the predictions of these two gravitational models. As a general result it turns out that for all the considered equations of state, EiBI gravity stars are more massive than their general relativistic counterparts. Furthermore, an exact solution of the spherically symmetric field equations in EiBI gravity, describing an "exotic" star, with decreasing pressure but increasing energy density, is also obtained. As a possible astrophysical application of the obtained results we suggest that stellar mass black holes, with masses in the range of $3.8M_{\odot}$ and $6M_{\odot}$, respectively, could be in fact EiBI neutron or quark stars.

description: A new metal–organic framework with the chemical formula [Co2(ptptc)·(H2O)3](MeOH) (1) was synthesized using Co(NO3)2· 6H2O and terphenyl-3,3″,5,5″-tetracarboxylic acid (H4ptptc) as the starting materials under solvothermal conditions. Removal of the lattice solvent molecules and the coordinated water molecules resulted in porous framework 1a having a high density of open metal sites. In the presence of trimethylsilyl cyanide, catalytic activity for the cyanosilylation of the aromatic aldehydes was observed, with different substituents in distinct positions, and provided cyanohydrin trimethylsilyl ethers with shape- and size-selective catalysis. Furthermore, the biological function and detailed mechanism of anti-cancer action of the compound were assessed. The CCK-8 assay was carried out to determine the compound’s inhibitory function on cell viability. The influence of the compound on cell invasion and migration was studied via the transwell method. Finally, the reverse transcription polymerase chain reaction was used to reveal the mechanism of the compound by measuring the expression level of racl1 and racl2 in CAES-17 esophageal cancer cells.

description: Malignant tumors have become one of the challenges to global human health today, and the development of new drugs has become a research hotspot for tumor treatment. In order to prove that copper(II)-thiosemicarbazone complexes can be used as antibacterial and antitumor agents, we have synthesized and characterized three copper(II) complexes (C1-C3). These Cu(II) complexes exhibited excellent anticancer and antimicrobial activity, and greatly exceed the corresponding metal-free ligands. C3 has the highest anti-proliferative activity (0.20 ± 0.04 µM) against A549 (human lung carcinoma cell lines) and the best inhibitory zone diameter (25.78 ± 0.18 mm) against E. coli. The lipophilicity of the ligand is closely related to the anti-proliferative and antibacterial activities of these Cu(II) complexes. The study of the cellular mechanism demonstrates that these Cu(II) complexes promoted cell apoptosis by catalyzing hydrogen peroxide to produce intracellular reactive oxygen species (ROS). Antibacterial experiments showed that these Cu(II) complexes exhibited potent antibacterial activities, especially against gram-negative bacteria. These Cu(II) complexes may initially cause outer membrane/lipopolysaccharide (LPS) instability, disrupt cell membranes, and ultimately lead to bacterial cell lysis.

description: We present the chemical analysis of 49 giant stars of the globular cluster NGC 2419, using medium resolution spectra collected with the multi-object spectrograph DEIMOS@Keck. Previous analysis of this cluster revealed a large dispersion in the line strength of the infrared Ca II triplet, suggesting an intrinsic star-to-star scatter in its Fe or Ca content. From our analysis, we assess that all the investigated stars share the same [Fe/H], [Ca/Fe] and [Ti/Fe] abundance ratios, while a large spread in Mg and K abundances is detected. The distribution of [Mg/Fe] is bimodal, with ~40% of the observed targets having subsolar [Mg/Fe], down to [Mg/Fe] ~ -1 dex, a level of Mg-deficiency never observed before in globular clusters. It is found that the large dispersion in Mg abundances is likely the main origin of the observed dispersion of the Ca II triplet lines strengths (that can be erroneously interpreted in terms of Fe or Ca abundance scatter) because Mg plays a relevant role in the atmosphere of giant stars as an electron donor. A strong depletion in the Mg abundance leads to an increase of the line strength of the Ca II triplet, due to the variation in the electronic pressure, at a constant Fe and Ca abundance. Finally, we detect an anti-correlation between Mg and K abundances, not easily explainable within the framework of the current nucleosynthesis models.

Metabolic biomarker responses in acute cerebral events

Publisher: name: Imperial College London
Year: 2020

description: Aims The aims of this study were to identify a potential blood biomarker for acute stroke and additionally to identify biomarkers capable of differentiating hyper-acute ischaemic from haemorrhagic stroke using metabonomic techniques. Methodology Following ethical approval participants were recruited from the hyper-acute stroke unit at Charing Cross Hospital and acute blood samples taken from patients who were suspected of having an acute stroke. Serum was extracted and frozen prior to MS and NMR analysis. Sub-acute TIA patients were used as a comparative group and patients with known atherosclerotic disease as a non-acute control group. A total of 90 participants were recruited for analysis. Positive and negative mode reverse phase UPLC-MS and additionally 1H-NMR spectroscopy were used to analyse prepared serum samples. Modelling was performed using OPLS-DA and CA-PLS techniques where appropriate following permutation analysis to detect discriminatory metabolites between participant groups. Results Positive mode mass spectrometry detected metabolites that could differentiate between participants who had suffered an acute cerebral ischaemic event (inclusive of stroke and acute TIA) and those participants that were known to have established atherosclerotic disease. The metabolites detected include phosphatidylcholines, sphingomyelins and a ganglioside. Unfortunately, due to a relatively small sample size the CA-PLS false discovery rate analysis found the initial results to lack statistical significance (Q value = 0.95). It was not possible to metabolically differentiate between acute ischaemic and haemorrhagic strokes. Conclusion Despite the relatively small sample size leading to a confirmed false discovery rate analysis the initial findings of elevated phosphatidylcholines, sphingomyelins and the peripheral detection of a ganglioside in relation to acute cerebral ischaemia is promising and follows a trend in the published literature. Further studies with a larger sample size, rigorous follow up and temporal trend analysis using dedicated lipidomic techniques may find a sensitive diagnostic serological biomarker for hyper-acute stroke and transient ischaemic attack.

Mechanisms of liver regeneration in a clinical model for preoperative induction of liver hypertrophy prior to major liver resection
Creators: name: Fajardo Puerta, Ana Belen
Publisher: name: Imperial College London
Year: 2021

description: The liver is a central organ for homeostasis and has the unusual and remarkable property of regeneration with rapid restoration of its volume and function. Liver regeneration (LR) is a very enigmatic and complex process involving numerous intra and extrahepatic signals and pathways. Interestingly, genetic knockdown studies have often demonstrated delays in the course of regeneration, but no single signal has been identified to be both sufficient and necessary for LR. Furthermore, LR can be modified by multiple patient, liver or trauma-related factors. As a consequence, diverse clinical applications have been developed and used extensively including hepatic resections to remove liver tumours, split liver transplantation from donors, portal vein occlusion, artificial support in acute liver insufficiency or cellular therapy. Recently, a surgical technique named associated liver partition with portal vein ligation for staged hepatectomy (ALPPS) has shown an unprecedented property of accelerating LR. This procedure results in a greater speed of cell hypertrophy in the future liver remnant when compared with the gold standard portal vein embolization (PVE). These techniques are used for preoperative optimization of a small future liver remnant, avoid postoperative liver failure and, in turn, improve morbidity and mortality. Unfortunately, tumoral progression has been observed after PVE precluding the potential of curative hepatectomy. The ALPPS procedure may speed this hepatic resection and increase resectability rates. However, due to its associated high morbidity and mortality rates, diverse groups have developed modifications of the ALPPS technique (ALPPS variants). This includes radiofrequency assisted liver partition ablation with portal vein ligation for staged hepatectomy (RALPPS). By associating a line of necrosis with radiofrequency ablation following portal vein ligation, this two-stage technique allows a safe and rapid LR without an increased morbidity or mortality associated with the procedure. Herein, a general review of the process of LR is presented as well as further research of the intrinsic mechanisms of LR induced by PVE and the ALPPS variant, RALPPS.

description: The dominant contribution to the theoretical uncertainty in the extracted weak parameters of the Standard Model comes from the hadronic uncertainties in the electroweak boxes, i.e. $\gamma-W^\pm/Z$ exchange diagrams. A dispersive analysis relates the box diagrams to the parity-odd structure function, $F_3$, for which the experimental data either do not exist or belong to a separate isospin channel. Therefore a first-principles calculation of $F_3$ is highly desirable. In this contribution, we report on the QCDSF/UKQCD Collaboration's progress in calculating the moments of the $F_3^{\gamma Z}$ structure function from the forward Compton amplitude at the SU(3) symmetric point.

description: Solar twins have been a focus of attention for more than a decade, because their structure is extremely close to that of the Sun. Today, thanks to high-precision spectrometers, it is possible to use asteroseismology to probe their interiors. Our goal is to use time series obtained from the HARPS spectrometer to extract the oscillation frequencies of 18 Sco, the brightest solar twin. We used the tools of spectral analysis to estimate these quantities. We estimate 52 frequencies using an MCMC algorithm. After examination of their probability densities and comparison with results from direct MAP optimization, we obtain a minimal set of 21 reliable modes. The identification of each pulsation mode is straightforwardly accomplished by comparing to the well-established solar pulsation modes. We also derived some basic seismic indicators using these values. These results offer a good basis to start a detailed seismic analysis of 18 Sco using stellar models.

description: In this study, the novel phthalonitrile derivatives 1 and 2 were synthesized. Tetra-substituted metal-free 1a (H2Pc) and metallophthalocyanines (ZnPc 1b, CoPc 1c and CuPc 1d) bearing four peripheral 4-allyl-2,6-dimethoxyphenol (methoxy-eugenol) groups and octa-substituted metal-free 2a and metallophthalocyanines (ZnPc 2b, CoPc 2c and CuPc 2d) bearing eight peripheral methoxy-eugenol group were synthesized. All new synthesized compounds are characterized by IR, 13C{1H} NMR (for 1 and 2), UV-Vis (for 1a–2d) and mass spectroscopy. Antimicrobial activities of the synthesized phthalonitrile derivatives (1 and 2) and phthalocyanine compounds 1a–2d were determined by microdilution broth method against nine different bacteria and one yeast species. In this study, CoPc (2c) compound, which has eight peripheral 4-allyl-2,6-dimethoxyphenol, had the highest antibacterial activity (minimum inhibitory concentration [MIC] = 312 μg/mL). In addition, 1b, 1d, 2b and 2d were found to be effective on at least three different bacterial species at different concentrations (MIC = 1250–5000 μg/mL). Shigella flexneri were the most affected bacteria, but none of the compounds were effective against fungal isolate.

description: Using the CFBDSIR wide field survey for brown dwarfs, we identified CFBDSIRJ214947.2-040308.9, a late T dwarf with atypically red J-Ks colour. We obtained an X-Shooter spectra, with signal detectable from 0.8 to 2.3 micron, which confirmed a T7 spectral type with an enhanced Ks-band flux indicative of a potentially low-gravity, young, object. The comparison of our near infrared spectrum with atmosphere models, for solar metallicity, shows that CFBDSIRJ214947.2-040308.9 is probably a 650-750 K, log g=3.75-4.0 substellar object. Using evolution models, this translates into a planetary mass object, with an age in the 20-200 Myr range. An independent Bayesian analysis from proper motion measurements results in a 87% probability that this free-floating planet is a member of the 50-120 Myr old AB Doradus moving group, which strengthens the spectroscopic youth diagnosis. By combining our atmospheric characterisation with the age and metallicity constraints arising from the probable membership to the AB Doradus moving group, we find that CFBDSIRJ214947.2-040308.9 is probably a 4-7 Jupiter masses free-floating planet with an effective temperature of ~700K and a log g of ~4.0, typical of the late T-type exoplanets that are targeted by direct imaging. We stress that this object could be used as a benchmark for understanding the physics of the similar T-type exoplanets that will be discovered by the upcoming high contrast imagers.

description: This article describes synthesis and characterization of three oxidovanadium(IV) complexes using BPA (BPA = 2,2’-bis(pyridylmethyl)amine), 2,2-bipyridyl and 1,10-phenanthroline. These complexes were characterized by elemental analysis, spectroscopic (UV-vis, IR and EPR) and electrochemical methods. Room temperature magnetic susceptibility data show the paramagnetic nature of the complexes. Complexes were also characterized by electron paramagnetic resonance (EPR) spectral techniques. The optimized molecular structures show the presence of N3O3/N5O donor atoms in six-coordinate geometry. These complexes were evaluated and compared using thermogravimetric analysis and powder X-ray diffraction techniques. The species exhibit only one-electron reduction wave at a more negative potential. The catalytic activity of these complexes was also explored to mimic α-glucosidase and α-amylase activity. Moderate α-glucosidase and α-amylase inhibitors are shown by all complexes. These observations are expected to expand the possibility of designing new oxidovanadium(IV) complexes with significant anti-diabetic properties.

Acoustic characterisation of the roughness of reflective surfaces
Creators: name: Dawson, Peter James
Publisher: name: Imperial College London
Year: 2021

description: The field of rough surface classification is largely focused on optical solutions. There are situations however, where an acoustic method for obtaining information about a surface's texture is required. This thesis investigates the relationship between acoustic reflections from rough surfaces and the resulting signals at a microphone array, and develops methods to find information about the reflecting surface from the array signals in order to build up the knowledge of the object's characteristics for identification. Two methods are explored. The first method exploits the relationship between the distribution of visible image-sources and the surface roughness to achieve an estimation of its parameters. The method requires knowledge of image-sources, so an investigation is carried out into methods for localising image-sources of reflections from a rough surface when presented with microphone array signals and geometry and assuming knowledge of the source signal and geometry. The second method uses an interferometry based method with a tailored source signal in order to probe a surface for a roughness. The contrast of signal power at the microphone array as the centre frequency is varied is explored, and the ability of the resulting contrast profiles in classifying surface roughness is assessed. The methods are assessed using a dataset of reflections from rough surfaces, modelled using BEM, from which microphone array signals can be extracted.

description: This paper investigates complex formation in the Fe(II)-Fe(III)-acrylamide-water system. Dependences of oxidative potentials on the concentration and model parameters of iron acrylamide complexes are discussed. Effect of reaction pH on polymerization of acrylamide and applications of polyacrylamide crosslinking reactions are described. At low pH and high temperatures, formation of water-insoluble cross-linked polymers is possible due to creation of imide bridges between the macromolecules (–CO–NH–CO–). Calculations of the formation constants according to their chemical and physical properties such as pH, temperature and ionic strength of the solution are outlined. Chemical models of acrylamide coordination compounds with Fe(III) and Fe(II) at 298.16 K and energy J = 0.5 are shown in this article. A chemical model of the equilibria numerical values of the complexes for oxidized and reduced forms of the metal, the number of protons they contain, the number of coordinated ligands, hydroxyl groups (g, p, s, l and k), are calculated by comparing the slopes of the experimental curves and partial derivative oxidative potentials of concentration variables. Dependences of the Fe(II) and Fe(III) complexes formation on pH for the systems of Fe(II)-Fe(III)-acrylamide-H2O have been determined.

Modelling active case-finding strategies for tuberculosis in urban India
Creators: name: Cilloni, Lucia
Publisher: name: Imperial College London
Year: 2021

description: India harbours the world’s largest burden of tuberculosis, with approximately 27% of the estimated global burden. Although considerable measures have been taken since the roll-out of the End TB strategy, in 2015, to increase case detection and improve treatment quality, the overall quality of care remains poor and estimates on incidence remain highly uncertain, because of the poor notification rates, especially from the private healthcare sector, where nearly half of all individuals seek care. In 2017, India’s National Strategic Plan for Tuberculosis Elimination brought forward extremely ambitious targets of an 80% reduction in incidence by 2025. The first step of the plan proposes a scale-up of case-detection through active case-finding, in order to increase case notification rates and reduce the diagnostic and treatment initiation delays, often associated with tuberculosis care. The evidence for the value of active case-finding interventions for tuberculosis, however, is mixed and highlights a substantial geographical imbalance of studies. A recent systematic review has encouraged the implementation of targeted active case-finding interventions, suggesting these may have an important effect on the prevalence of disease. Despite this, there remains some scepticism around these interventions, which can be costly and difficult to implement on a large scale, and because of the diverse number of factors that can affect their impact. This thesis aims to investigate the value of routine active case-finding interventions in high-burden settings, implemented using available tools for screening and diagnosis. Epidemiological data is used in the development of the mathematical models used in the analyses, and costing information is included to allow an estimation of the financial implications of this undertaking.

description: We study experimentally and theoretically the properties of structural defects (kink solitons) in two-dimensional ion Coulomb crystals. We show how different types of kink solitons with different physical properties can be realized, and transformed from one type into another by varying the aspect ratio of the trap confinement. Further, we discuss how impurities in ion Coulomb crystals, such as mass defects, can modify the dynamics of kink creation and their stability. For both pure and impure crystals, the experimentally observed kink dynamics are analyzed in detail and explained theoretically by numerical simulations and calculations of the Peierls-Nabarro potential. Finally, we show that static electric fields provide a handle to vary the influence of mass defects on kinks in a controlled way and allow for deterministic manipulation and creation of kinks.

description: The synthesized thioureas, 1-(3-fluorobenzoyl))-3-(4-(diethyl aminophenyl) thiourea (I1), 1-benzoyl-3-(2-chlorophenyl) thiourea (I2) and 1-(2-fluorobenzoyl)-3-(2-chlorophenyl) thiourea (I3) along with triphenylphosphine were reacted with Cu(I) chloride in mole ratios 1:2:1 by using dry acetone as solvent under nitrogen to get 1–3. The synthesized thioureas and metal derivatives were characterized by spectroscopic techniques such as IR and multinuclear (1H, 13C) NMR. Compound 3 is analyzed by single crystal X-ray analysis and data reveal that the Cu is four coordinate having tetrahedral molecular geometry. The interaction of 1–3 with DNA is ascertained by cyclic voltammetry, determining binding constant, binding energy and diffusion coefficient. The findings suggest that the complexes interact with DNA in an electrostatic mode. The antioxidant activity data show that 3 has the highest free radical scavenging ability having Ic50 value of 10 µg/mL. The synthesized compounds were also screened against various bacterial strains and found some encouraging results. The binding interactions of the metal complexes with a specific protein were further validated by molecular docking studies and the results obtained show their strong interaction with amino acid residue in the binding pocket of the target protein.

description: In this paper we provide general conditions on a one parameter family of random infinite subsets of Z^d to contain a unique infinite connected component for which the chemical distances are comparable to the Euclidean distances, focusing primarily on models with long-range correlations. Our results are in the spirit of those by Antal and Pisztora proved for Bernoulli percolation. We also prove a shape theorem for balls in the chemical distance under such conditions. Our general statements give novel results about the structure of the infinite connected component of the vacant set of random interlacements and the level sets of the Gaussian free field. We also obtain alternative proofs to the main results in arXiv:1111.3979. Finally, as a corollary, we obtain new results about the (chemical) diameter of the largest connected component in the complement of the trace of the random walk on the torus.

description: A Cd(II)-based one-dimensional coordination polymer (1-D CP), [Cd2(mes)2(4-phpy)4] (1), was prepared using mesaconic acid (H2mes) and 4-phenyl pyridine (4-phpy) mixed ligand system. Compound 1 has been characterized by elemental analysis, infrared spectroscopy, thermogravimetric analysis (TGA), powder X-ray diffraction (PXRD) pattern and single crystal X-ray diffraction (SCXRD) techniques. Structural elucidation reveals a 1-D chain which contains a 14-membered metal-ligand ring composed of two mes ligands and two Cd(II) centers. Further, the 1-D chains are assembled into a two-dimensional (2-D) supramolecular network by C–H···π(metal-ligand ring) interactions. The fluorescence lifetime of 1 shows a good range of average lifetime. The theoretical band gap has also been calculated by density functional theory (DFT) computations, which shows that 1 may possess semiconducting properties.

description: Photon-number correlation measurements are performed on bright squeezed vacuum states using a standard Bell-test setup, and quantum correlations are observed for conjugate polarization-frequency modes. We further test the entanglement witnesses for these states and demonstrate the violation of the separability criteria, which infers that all the macroscopic Bell states, containing typically $10^6$ photons per pulse, are polarization entangled. The study also reveals the symmetry of macroscopic Bell states with respect to local polarization transformations.
