description: PLEASE DON'T DOWNLOAD THIS,GO TO THE LAST VERSION INSTEADLast version as I write this: 104

My last version when I write this is 103, Version 100 is the right one.

Please refer to Version 100. The constraints I thought were not satisfied were actually satisfied. All the x_k must be real so all the $\Delta_{n-k}$ must be positive.

Nothing to see. All the constraints I relied on proved to be loose. I need more refinement.

In the part with the quadratic equations which I relied on, with the constraint on $r_n$ as the quadratic coefficient $f_{n-k-1}$ of the new $\Delta_{n-k}$ got negative (to require the following $\Delta_{n-k-1} \ge 0$), I figured out that this constraint on $r_n$ was valid only up to a certain point; and to figure out this $k$ up to which the constraint holds, I had to express $r_n=\frac{\sum_{k=1}^{n} \frac{1}{k^{2a_n}}}{\sum_{k=1}^{n} \frac{1}{k^{2a_n}}-\left(\sum_{k=1}^{n}\right)^2}$ which in the end made the quadratic equations obsolete. Because I would anyway have to express $r_n$ this latter way.

In my previous versions, I really didn't pay attention to the $k$ up to which we needed the $\Delta_{n-k}$ positive. I assumed we needed all of them positive. Which is false, when the quadratic coefficient of one of them got positive it just broke the chain of constraints.

In the present study, even the $a_{+\infty} < \frac{1}{2}$ doesn't hold, I rushed while replacing with the asymptotic equivalence, we actually end up with 0=0 here as well.

What was very vile with that approach with the quadratic equations is that it seemed to make so much sense, with the $1-2a_n$ appearing here and there, but didn't make any in the end.

I feel dumb now. Thank you all for you attention.

I am sorry.

I am currently figuring out new constraints, I keep you updated whenever I can. We may even get back our beloved chain of quadratic equations.

description: Due to the fluctuating demand from the grid and the fluctuating feed from renewable sources of energies, conventional power plants are forced to operate under low load conditions to meet the requirement of variable power output. Under low load conditions, rotor of some turbine stages undergoes compressor mode, which leads to loss of power output. This also leads to increased enthalpy and pressure downstream of rotor. A parametric study is performed on steam turbine cylinder to understand the effects of thermal boundary conditions on the initiation of the so-called compressor mode.

description: Understanding the changing needs of consumers is an important element of building a competitive advantage of the company. The aim of the article is to present consumer behavior on the local market of organic products. The article presents issues related to the organic food market. The concept of organic product was defined and characterized, control and certification of organic production as well as factors affecting food quality and demand for organic products were discussed. In addition, a survey was conducted on the local market to show the determinants of consumer behaviour on the organic food market. Based on the surveys carried out and the analysis of statistical data, it can be seen that the modern consumer is aware of what he is buying. The quality and composition of the product are the most important factors that influence the decision they make. Consumers are increasingly giving up the consumption of traditional food in favor of organic products. / Synopsis.

description: Future instruments need efficient coronagraphs over large spectral ranges to enable broadband imaging or spectral characterization of exoplanets 1e8 fainter than their star. Several solutions were proposed. Pupil apodizers can attenuate the star intensity by a 1e10 factor but they transmit a few percents of the planet light only. Cascades of phase/amplitude masks can both attenuate the starlight and transmit most of the planet light but the number of optics to align is not a practical solution for an instrument. Finally, vector phase masks can be used to detect faint sources close to bright stars but they require the use of high quality circular polarizers and as for the previous solution, this leads to a complex instrument with numerous optics to align and stabilize. We propose simple coronagraphs that need one scalar phase mask and one binary Lyot stop only providing high transmission for the planet light (>50%) and high attenuation of the starlight over a large spectral bandpass (~30%) and a 360 degree field-of-view. From mathematical considerations, we find a family of 2D-phase masks optimized for an unobscured pupil. One mask is an azimuthal wrapped vortex phase ramp. We probe its coronagraphic performance using numerical simulations and laboratory tests. From numerical simulations, we predict the wrapped vortex can attenuate the peak of the star image by a factor of 1e4 over a 29% bandpass and 1e5 over a 18% bandpass with transmission of more than 50% of the planet flux at ~4 lambda/D. We confirm these predictions in laboratory in visible light between 550nm and 870nm. We also obtain laboratory dark hole images in which exoplanets with fluxes that are 3e-8 times the host star flux could be detected at 3sigma. Taking advantage of a new technology for etching continuous 2D-functions, new type of masks can be easily manufactured opening new possibilities for broadband coronagraphy.

description: We discuss domain walls and vacuum energy density (cosmological constant) in N=1 gluodynamics and in non-supersymmetric large N orientifold field theories which have been recently shown to be planar equivalent (in the boson sector) to N=1 gluodynamics. A relation between the vanishing force between two parallel walls and vanishing cosmological constant is pointed out. This relation may explain why the cosmological constant vanishes in the orientifold field theory at leading order although the hadronic spectrum of this theory does not contain fermions in the limit N-->infinity. The cancellation is among even and odd parity bosonic contributions, due to NS-NS and R-R cancellations in the annulus amplitude of the underlying string theory. We use the open-closed string channel duality to describe interaction between the domain walls which is interpreted as the exchange of composite ``dilatons'' and ``axions'' coupled to the walls. Finally, we study some planar equivalent pairs in which both theories in the parent-daughter pair are non-supersymmetric.

Outside-In : exploring spatial flexibility for the embodiment of different emotions
Creators: name: Tecson, Tricia Marie
Publisher: name: The University of British Columbia
Year: 2020

description: Designed spaces affect us physically, mentally and emotionally whether we know it to be or not. An emotional response that one experiences in a piece of architecture, whether it be wonder, contempt, sadness, boredom, fear or stress, is inevitable. Through looking at the cognitive psychology process of emotions and its connection to environmental design, I aim to gain a greater understanding in the connection of a person in space. Additionally, how space, ever changing, can be perceived in differing ways. Furthermore, applying this to the conceptual portion of design. In film, the design of a cinematic space is often accredited to evoking the many different emotions of storytelling within the confines of their fantasies. The techniques in production design enforce that the built environment envisions and executes these fabricated fantasies, bleeding into the physical world of cinematic architecture. Architecture and its audience share a deep relationship through the experiences and the emotions felt within the space. As designers we can captivate through the emotional bonds created in the history and narrative of the architecture. We can incorporate film techniques to engage the emotional bond and further the architectural influence on one’s emotions. In the design approach, this thesis will engage in the ideas of how emotions and narrative can affect the built environment. I look into three specific emotions and create scenes for them that are set in the same space. I take this existing space, known for its frequent use in the film industry, and “renovate” it to incorporate different architectural interventions that can help facilitate the transformation of said space. In combining the aspects of psychology, film and architecture, I aspire to bring a greater understanding of one’s emotional response one experiences in a piece of architecture and film. Thereby designing more deliberate and engaging environments in the future.

description: The current studies endeavour to develop and validate a simple, sensitive and robust reversed- phase (RP) high-performance liquid chromatography (HPLC) methodology for quantitative estimation of voriconazole (VRC), following systematic principles of Analytical Quality-by-Design (AQbD). A comprehensive risk assessment plan, followed by factor screening studies employing Taguchi design, was executed to select “vital few” critical method parameters, influencing critical analytical attributes. Subsequently, response surface optimisation studies were conducted on the identified critical method parameters, viz., mobile phase ratio and flow rate, with chosen critical analytical attributes, viz., peak area, theoretical plate count, retention time and peak tailing, employing a Central Composite Design. The design space, demarcating the optimal method operating conditions, was identified using graphical optimisation and subsequently validated employing Monte Carlo simulations. The optimal solution consisted of acetonitrile and acetic acid solution (0.05 %, pH 4) as mobile phase (50:50 v/v), flow rate of 1 mL/ min with a detection wavelength of 256 nm, exhibiting linearity between 0.1 and 50 μg/mL in methanol and Hanks balanced salt solution. Validation studies confirmed precision (97.78-103.42 %), accuracy (98.99-102.34 %), and suitability of the developed analytical method for effective quantification of VRC with high sensitivity (LOD: 0.031 μg/mL; LOQ: 0.093 μg/mL). The validated analytical technique was successfully ratified for quantification of VRC in drug nanoformulations too. In a nutshell, the application of AQbD and Monte Carlo simulations aided in developing a robust analytical method for the estimation of VRC per se as well as in drug nanoformulations.

description: Magnetized high energy density physics offers new opportunities for observing magnetic field-related physics for the first time in the laser-plasma context. We focus on one such phenomenon, which is the ability of a laser-irradiated magnetized plasma to amplify a seed magnetic field. We performed a series of fully kinetic 3D simulations of magnetic field amplification by a picosecond-scale relativistic laser pulse of intensity $4.2\times 10^{18}$ W/cm$^2$ incident on a thin foil. We observe axial magnetic field amplification from an initial 0.1 kT seed to 1.5 kT over a volume of several cubic microns, persisting hundreds of femtoseconds longer than the laser pulse duration. The magnetic field amplification is driven by electrons in the return current gaining favorable orbital angular momentum from the seed magnetic field. This mechanism is robust to laser polarization and delivers order-of-magnitude amplification over a range of simulation parameters.

description: Phosphatidylinositol 3-kinase (PI3K) inhibitors are emerging novel class of anticancer drugs. In this work, we report the development and validation of an LC-MS/MS method for the simultaneous quantitation of three PI3K inhibitors namely copanlisib, duvelisib and idelalisib in mouse plasma as per the FDA regulatory guidelines. Liquid-liquid extraction was used to extract copanlisib, duvelisib and idelalisib along with internal standard (I.S; filgotinib) from mouse plasma. Thereafter, chromatographic separation was achieved on an Ascentis Express RP-amide column using an isocratic mobile phase (5 mM ammonium acetate and acetonitrile in the ratio of 25:75, v/v) at a flow-rate of 0.5 mL/min. The analytes and I.S were detected by positive electrospray ionization tandem mass spectrometry (ESI-MS/MS) operated in multiple-reaction-monitoring (MRM) mode. The analytical time was 2.50 min in total. The calibration curve ranged from 4.41-1029, 0.70-1395 and 0.77-1544 ng/mL for copanlisib, duvelisib and idelalisib, respectively. The intra-assay accuracy and precision were ≤108 % and ≤6.23 %; ≤95.8 % and ≤13.1 %; and ≤101 % and ≤7.92 % for copanlisib, duvelisib and idelalisib, respectively and the inter-assay accuracy and precision were ≤107 % and ≤6.13 %; ≤97.6 % and ≤9.41 %; and ≤100% and ≤7.79 % for copanlisib, duvelisib and idelalisib, respectively. The validated method was successfully applied to a pharmacokinetic study in mice.

description: We develop continuum theory of self-assembly and pattern formation in metallic microparticles immersed in a poorly conducting liquid in DC electric field. The theory is formulated in terms of two conservation laws for the densities of immobile particles (precipitate) and bouncing particles (gas) coupled to the Navier-Stokes equation for the liquid. This theory successfully reproduces correct topology of the phase diagram and primary patterns observed in the experiment [Sapozhnikov et al, Phys. Rev.

description: We demonstrate a dynamical origin for the dimension-five seesaw operator in dimensional deconstruction models. Light neutrino masses arise from the seesaw scale which corresponds to the inverse lattice spacing. It is shown that the deconstructing limit naturally prefers maximal leptonic mixing. Higher-order corrections which are allowed by gauge invariance can transform the bi-maximal into a bi-large mixing. These terms may appear to be non-renormalizable at scales smaller than the deconstruction scale.

description: We derive a simple formula for the real-space chirality of twisted bilayer graphene that can be related to the cross-product of its sheet currents. This quantity shows well-defined plateaus for the first remote band as function of the gate voltage which are approximately quantized for commensurate twist angles. The zeroth plateau corresponds to the first magic angle where a sign change occurs due to an emergent $C_6$-symmetry. Our observation offers a new definition of the magic angle based on a macroscopic observable which is accessible in typical transport experiments.

description: In this paper we report a comprehensive study of the magnetic susceptibility (χ), resistivity (ρ), and specific heat (C_P), down to 0.5 K of the cubic CeIn_(3-x)Sn_x alloy. The ground state of this system evolves from antiferromagnetic (AF) in CeIn_3(T_N=10.2 K) to intermediate-valent in CeSn_3, and represents the first example of a Ce-lattice cubic non-Fermi liquid (NFL) system where T_N(x) can be traced down to T=0 over more than a decade of temperature. Our results indicate that the disappearance of the AF state occurs near x_c ~ 0.7, although already at x ~ 0.4 significant modifications of the magnetic ground state are observed. Between these concentrations, clear NFL signatures are observed, such as ρ(T)\approx ρ_0 + A T^n (with n<1.5) and C_P(T)\propto -T ln(T) dependencies. Within the ordered phase a first order phase transition occurs for 0.25 < x < 0.5. With larger Sn doping, different weak ρ(T) dependencies are observed at low temperatures between x=1 and x=3 while C_P/T shows only a weak temperature dependence.

description: The aim of present work is to develop and validate two simple and specific methods for the estimation of alprazolam hydrochloride (a psychoactive drug) in pharmaceutical formulations. The first method involves HPLC separation on the Cosmosil C-8 column using acetonitrile and potassium phosphate buffer (pH 6.0±0.1) (40:60 v/v) as mobile phase. The peak was obtained at 3.01±0.02 min. The effluent was monitored at 254 nm. The second method is based on HPTLC using Acetic acid: water: methanol: ethyl acetate (2:15:20:80 v/v/v/ v) as mobile phase and detection of the spot was carried out at 254 nm. The Rf value was found to be 0.76±0.02. The methods were validated as per ICH guidelines. The linearity curves were found to be linear over the concentration range 50-150 μg/ ml for HPLC and 50-400 ng/spot for HPTLC with a high correlation coefficient (R2 = 0.991 and 0.9987 respectively). The limit of detection and limit of quantification were found to be 1.66 and 5.04 μg/ml for HPLC and14.84 and 44.097 μg/ ml for HPTLC, respectively. The proposed methods are successfully used for the quality control of alprazolam in commercial form. Statistical analysis results confirmed that the methods are selective and precise.

description: We examine the counts-in-cells probability distribution functions that describe dark matter halos in the Dark Energy Universe Simulations (DEUS). We describe the measurements between redshifts $z=0$ to $z=4$ on both linear and non-linear scales. The best-fits of the gravitational quasi-equilibrium distribution (GQED), the negative binomial distribution (NBD), the Poisson-Lognormal distribution (PLN), and the Poisson-Lognormal distribution with a bias parameter (PLNB) are compared to simulations. The fits agree reasonably consistently over a range of redshifts and scales. To distinguish quintessence (RPCDM) and phantom ($w$CDM) dark energy from $Λ$ dark energy, we present a new method that compares the model parameters of the counts-in-cells probability distribution functions. We find that the mean and variance of the halo counts-in-cells on $2-25h^{-1}$Mpc scales between redshifts $0.65

String excitation energies in SU(N) gauge theories beyond the free-string approximation

description: In the presence of a static quark--antiquark pair, the spectrum of the low-lying states in SU($N$) gauge theories is discrete and likely to be described, at large quark separations $r$, by an effective string theory. The expansion of the excitation energies in powers of $1/r$, which derives from the latter, involves an increasing number of unknown couplings that characterize the string self-interactions. Using open--closed string duality, we show that the possible values of the couplings are constrained by a set of algebraic relations. In particular, the corrections of order $1/r^2$ must vanish, while the $1/r^3$ terms (which we work out for the few lowest levels) depend on a single adjustable coupling only.

A Possible Proof Of The Riemann Hypothesis

description: In this paper, I present my approach to the Riemann Hypothesis, which potentially provides elements for a proof of it.

I start by simplifying the equality Eta(s)=0 (which is implied by the nullness of the continued Zeta(s)) by expressing |Eta(s)|^2=0 as Re(Eta(s))^2 + Im(Eta(s))^2 = 0, expressed with cosine and sine functions, then I use trigonometric identities to further break down the sum into a sum of squares purely relying on Re(s) and a double sum relying on both Re(s) and Im(s).

Using the bounded nature of the cosine function, I reformulate the equality as a problem of quadratic equations, to get rid of the dependence on Im(s) as well as the oscillations it induces,

I then consider Re(s) as a map a[n] = Re(s[n]) (n being the number of terms in Zeta(s) or Eta(s)), rather than a fixed value (since we deal with infinity),

It has already been proved that for all the nontrivial zeros, their real part is in ]0,1[,

So, I then use integrals and asymptotic analysis to observe three cases of asymptotic behaviours:

                        CURRENTLY UNDER CHANGE

when a[n] converges to a real number in ]0,1/2[

when a[n] converges to a real number in ]1/2,1[

when a[n] converges to 1/2 (where we distinguish some more cases)

Then I conclude that the only logically consistent case is when a[n] converges to 1/2.Or maybe not, but good attempt, I guess.

IMPORTANT NOTE: While I'm quite confident about my reasoning until the end of part 2 with the new equivalence solely involving Re(s), obtained thanks to the imbricated quadratic equations, I noticed there was a big hole in my reasoning in the 3rd part with the asymptotic behaviour analysis, and figured out some inconsistencies in my presumably "OK" case when the real part tends to 1/2, there's a couple of things I didn't take into account.

I'll update it whenever possible.

description: Two of the dominant channels to produce the black-hole binary mergers observed by LIGO and Virgo are believed to be the isolated evolution of stellar binaries in the field and dynamical formation in star clusters. Their relative efficiency can be characterized by a "mixing fraction." Pair instabilities prevent stellar collapse from generating black holes more massive than about $45 M_\odot$. This "mass gap" only applies to the field formation scenario, and it can be filled by repeated mergers in clusters. A similar reasoning applies to the binary's effective spin. If black holes are born slowly rotating, the high-spin portion of the parameter space (the "spin gap") can only be populated by black hole binaries that were assembled dynamically. Using a semianalytical cluster model, we show that future gravitational-wave events in either the mass gap, the spin gap, or both can be leveraged to infer the mixing fraction between the field and cluster formation channels.

description: The aim of the study was to analyse innovations implemented in the milk and meat industries, and their impact on increasing competitiveness. The study showed that the 2010-12 period saw the most product and process innovations being introduced. On the other hand, innovations in marketing were found to be more popular in 2013. Three groups of similar innovations were distinguished. The milk industry stood out when it comes to the extent of innovations implemented. Fewer innovations were found in the poultry meat industry. Beef and pork meat processing was the least innovative. The innovativeness of enterprises is greater with larger numbers of employees and the increase in scope of their field of operation. The implementation of innovations resulted in: improvement of the quality of goods (services), increase in stock, productive capabilities and revenues from sales, emergence of new markets, increase in competitiveness and prestige of the firm. Those are confirmed by the very good performance of foreign trade and better competitiveness rates of Polish meat producers.

description: Docetaxel (DOX) is one of the clinically used chemotherapeutic agents for the treatment of breast cancer, instead of its severe side effects. Noscapine, an antitussive opium alkaloid, on the other hand, has shown antitumor activity against a number of cancers without any significant side effects. Since both the compounds targeted tubulin, it is interesting to see the combined effect of both the compounds for the management of breast cancer. The binding energy of -3.49 and -4.18 kcal/mol respectively was noted by the molecular docking of amino-noscapine and DOX on the microtubule. In contrast, the binding energy was improved significantly (-6.27 kcal/mol) when the DOX was docked to the co-complex of amino-noscapine and tubulin, indicating the combined effect of both the ligands. The cell killing potential represented in terms of IC50 value was 38.07 μM and 28.4 μM for a treatment duration of 48 h and 72 h for amino-noscapine. Parenthetically the IC50 value was 0.61 μM and 0.08 μM for DOX respectively for the treatment duration of 48 h and 72 h. The cytotoxic effect of DOX was reduced significantly (to 0.05 μM) in combined treatment with amino-noscapine (20 μM). Apropos to the cytotoxic effect, both the compounds induced apoptosis to cancer cell by interfering with the cell cycle progression. Again, the induction of apoptosis was more effective in the combined treatment of both the compounds. This investigation offers a promising concept for the combination of DOX and aminonoscapine treatment to improve effectiveness in the treatment of breast cancer.

description: Motivated by a fundamental synchronization problem in scalable parallel computing and by a recent criterion for ``mean-field'' synchronizability in interacting systems, we study the Edwards-Wilkinson model on two variations of a small-worldnetwork. In the first version each site has exactly one random link of strength $p$, while in the second one each site on average has $p$ links of unit strength. We construct a perturbative description for the width of the stationary-state surface (a measure of synchronization), in the weak- and sparse-coupling limits, respectively, and verify the results by performing exact numerical diagonalization. The width remains finite in both cases, but exhibits anomalous scaling with $p$ in the latter for $d\leq 2$.
