Creators: name: Kochol, Martin
Publisher: name: Contributions to Discrete Mathematics
Year: 2020

description: A regular chain group $N$ is the set of integral vectors orthogonal to rows of a matrix representing a regular matroid, i.e., a totally unimodular matrix. Introducing canonical forms of an equivalence relation generated by $N$ and a special basis of $N$, we improve several results about polynomials counting elements of $N$ and find new bounds and formulas for these polynomials.

Militant Workers, Coopted Leaders: A Critical Assessment of Workers’ Collective Action Through Organized Labour in Tunisia

Workers Collective Action

description: This dissertation explores the dynamics of workers’ collective political engagement through organized labour in an authoritarian environment and a regime in transition. While the literature on social movements and organized labour in the Middle East and North Africa (MENA) has captured the characteristics and impact of repression and corporatist systems on a union structure and elite strategies, this research contributes to a body of work that position the activities, networks and calculations of unionized workers at the centre of analysis. Using the Tunisian General Labour Union as an in-depth case-study, it will show that to fully comprehend the important role of a labour union as a vehicle for political engagement, one must pay close attention to the networks, strategies, and tactics of its militant base. By adopting a conceptual framework that gives attention to interactions of structures and agents, and therefore not privileging one over the other, it shows how in a region in which unions were conventionally labelled as “inconsequential” and “empty shells,” unionized workers, particularly those belonging to more militant sectors, have repeatedly seized on their personal networks and relationships, while drawing on systems of meaning making and shared collective memory to engage in various forms of activism. By doing so, it underscores the limitations of cooptation as a political strategy for ensuring obedience and compliance. Moreover, to better understand workers’ activism and political engagement in MENA, this dissertation calls for a change in how “successful mobilization” is measured and assessed. In particular, it draws attention to the objectives and goals of workers’ collective action, aims that cannot always be equated with the pursuit of a standardized path to democracy developed largely by institutions located in the West.
On the uniformity of the approximation for $r$-associated Stirling numbers of the second Kind
Creators: name: Connamacher, Harold
name: Dobrosotskaya, Julia
Publisher: name: Contributions to Discrete Mathematics
Year: 2020

description: The $r$-associated Stirling numbers of the second kind are a natural extension of Stirling numbers of the second kind. A combinatorial interpretation of $r$-associated Stirling numbers of the second kind is the number of ways to partition $n$ elements into $m$ subsets such that each subset contains at least $r$ elements. Calculating the associated Stirling numbers is typically done with a recurrence relation or a generating function that are computationally expensive or alternatively with a closed-form that is practical for only a limited parameter range. In 1994 Hennecart proposed an approximation for the $r$-associated Stirling numbers that is fast to compute, is amenable to analysis over a wide range of parameters, and is conjectured to be asymptotically tight. There are a few other approximations for the associated Stirling numbers, but none of them are as general as Hennecart's. However, until this work, Hennecart's approximation had been utilized without a proper justification due to the absence of a rigorous proof. This work provides a proof of the uniformity of the Hennecart approximation.

Publisher: name: Contributions to Discrete Mathematics
Year: 2020

description: Sierpiński graphs are studied in fractal theory and have applications in diverse areas including dynamic systems, chemistry, psychology, probability, and computer science. Polymer networks and WK-recursive networks can be modeled by generalized Sierpiński graphs. The degree sequence of (ordinary) Sierpi\'nski graphs and Hanoi graphs (and some of their topological indices) are determined in the literature. The number of leaves (vertices of degree one) of the generalized Sierpiński graph $S(T, t)$ of any tree $T$ was determined in 2017 and in terms of $t$, $|V(T)|$, and the number of leaves of the base graph $T$. In this paper, we generalize these results. More precisely, for every simple graph $G$ of order $n$, we completely determine the degree sequence of the generalized Sierpiński graph $S(G,t)$ of $G$ in terms of $n$, $t$ and the degree sequence of $G$. By using it, we determine the exact value of the general first Zagreb index of $S(G,t)$ in terms of the same parameters of $G$.

description: At present it is considered that Christianity was declared a state religion in Georgia in circa 326 AD, during the reign of King Mirian and Queen Nana. In the Georgian Chronicle [1] (Kaukhchishvili, 1955) it is stated that this event is connected with the adoption of Christianity by King Mirian. Once he was hunting somewhere between Mtskheta (the ancient capital of Georgia) and Khashuri, near Mt. Tkhoti in dense woodland. It rapidly got dark and the Sun disappeared from the sky. Mirian began to ask his traditional pagan gods, but to no avail. Then he addressed the god whom Nino from Cappadocia believed in (subsequently she became Saint Nino, a woman whose name is inseparably linked with the spread of Christianity in Georgia) and there was a miracle; the darkness suddenly disappeared and the Sun began shining in the sky again. Then Mirian turned to the East and thanked "Nino's god". In the authors' opinion, the eclipse seen by King Mirian happened on the evening of 6 May, 319 AD. Later, in May 320 AD, cypress crosses were made and raised. Thus, we have answered the question raised 70 years ago by the Georgian historian Ivane Javakhishvili about the occurrence of a total solar eclipse in Georgia in the fourth century. The eclipse seen by King Mirian happened on the evening of 6 May, 319 AD. Later, in May 320 AD, cypress crosses were raised and Christianity was become the state religion of Georgia.

A classification of isomorphism-invariant random digraphs
Creators: name: Bahadir, Selim
name: Ceyhan, Elvan
Publisher: name: Contributions to Discrete Mathematics
Year: 2020

description: We classify isomorphism-invariant random digraphs \linebreak (IIRDs) according to where randomness lies, namely, on arcs, vertices, vertices and arcs together as arc random digraphs (ARD), vertex random digraphs (VRD), vertex-arc random digraphs (VARD) as an extension of the classification of isomorphism-invariant random graphs (IIRGs) \cite{beer:2011}, and introduce randomness in direction (together with arcs, vertices, etc.) also which in turn yield direction random digraphs (DRDs) and its variants, respectively. We demonstrate that for the number of vertices $n\ge 4$, ARDs and VRDs are mutually exclusive and are both proper subsets of VARDs, and also demonstrate the existence of VARDs which are neither ARDs nor VRDs, and the existence of IIRDs that are not VARDs (e.g., random nearest neighbor digraphs(RNNDs)). We demonstrate that to obtain a DRD as an IIRD, one has to start with an IIRG and insert directions randomly. Depending on the type of IIRG, we obtain direction-edge random digraphs (DERDs), direction-vertex random digraphs (DVRDs), and direction-vertex-edge random digraphs (DVERDs), and demonstrate that DERDs and DVRDs have an overlap but are mutually exclusive for $n \ge 4$, and both are proper subsets of DVERDs which is a proper subset of DRDs and also the complement of DRDs in IIRDs is nonempty (e.g., RNNDs). We also study the relation of DRDs with VARDs, VRDs, and ARDs and show that for $n\ge 4$, the intersection of DERDs and VARDs is ARDs; we provide some results and open problems and conjectures. For example, the relation of DVRDs and DVERDs with the VARDs (hence with ARDs and VRDs) are still open problems for $n \ge 4$. We also show positive dependence between the arcs of a VARD whose tails are same which implies the asymptotic distribution of the arc density of VRDs and ARDs has nonnegative variance.

Publisher: name: Contributions to Discrete Mathematics
Year: 2020

description: Let $G$ be a graph. A $G$-design of order $n$ is a decomposition of the complete graph $K_n$ into disjoint copies of $G$. The existence problem of graph designs has been completely solved for all graphs with up to five vertices, and all graphs with six vertices and up to seven edges; and almost completely solved for all graphs with six vertices and eight edges leaving two cases of order 32 unsettled. Up to isomorphism there are 20 graphs with six vertices and nine edges (and no isolated vertex). The spectrum problem has been solved completely for 11 of these graphs, and partially for 2 of these graphs. In this article, the two missing graph designs for the six-vertex eight-edge graphs are constructed, and a complete solution to the spectrum problem for the six-vertex nine-edge graphs is given; completing the spectrum problem for all graphs with six vertices and up to nine edges.

Identification of MMP-9 as a Driving Factor in SARS-CoV-2 Entry
Creators: name: Phan, Alexandra
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2021
Subjects: SARS-CoV-2

description: Since its emergence in December 2019, SARS-CoV-2 has infected over 200 million people globally. SARS-CoV-2 spike (S) decorates the viral envelope and is responsible for facilitating viral entry into the host cell. To mediate membrane fusion, S must be proteolytically cleaved. For the closely related SARS-CoV S, cleavage at the host cell surface must be facilitated by the serine protease TMPRSS2. We demonstrated that SARS-CoV-2 S can facilitate fusion independent of TMPRSS2 and sought to identify other proteases capable of driving SARS-CoV-2 S-mediated fusion. We show that the ADAMs and MMP inhibitor GI 254023X is capable of substantially reducing SARS-CoV-2 S-mediated syncytium formation. Additionally, we identified MMP-9, a protein target of GI 254023X, as a host protease capable of enhancing SARS-CoV-2 lentivirus entry in HEK293T-ACE2 cells. These results implicate ADAM and MMP proteases, in particular MMP-9, as potential antiviral drug targets against COVID-19 pathogenesis.
The ruby and pink sapphire deposits of SW Greenland : geological setting, genesis, and exploration techniques
Creators: name: Fagan, Andrew Jeffrey
Publisher: name: University of British Columbia
Year: 2018

description: The Aappaluttoq, Siggartartulik, and Kigutilik gem corundum deposits are hosted by the Fiskenæsset Anorthosite Complex in SW Greenland. These deposits are some of the largest ruby and sapphire deposits in the world yet have received little scientific attention. During regional granulite metamorphism (2817 Ma; U-Pb EMPA monazite), leucogabbroic rocks alter towards more Na-enriched compositions causing Ca-feldspar to recrystallize. This liberates the Al required for metamorphic opaque corundum formation in an orthogneissic host. Subsequent retrogression through the amphibolite facies (2747-2555 Ma, U-Pb EMPA monazite) and local scale hydrous metasomatism (2660 Ma, U-Pb EMPA monazite) causes recrystallization of the mineral assemblage and the formation of three distinct gem corundum bearing lithologies: 1) phlogopitite, 2) altered leucogabbro, 3) altered ultramafic rock containing sapphirine and gedrite-anthophyllite. Intrusion of local granitoids (2747-2714 Ma, U-Pb TIMS zircon) provided a hydrous fluid which infiltrated and metasomatised the regional assemblage and was channeled along preexisting lithological boundaries (leucogabbro-ultramafic, leucogabbro-melanogabbro). The primary host for gem corundum is the 2-8 meter wide phlogopitite unit formed at 700 to 815°C and 5 to 8 kbar. This unit contains up to 20% corundum, of which at least 5% is gem quality. The phlogopite represents the quenched granitic-metasomatic fluid; EMPA and LA-ICP-MS analysis confirm a fluid composition depleted in S, Cu, Ca, Pr, Nd, Sm, Te, Cs, Ba, Se and transition metals, and enriched in Rb, Sr, Cr, and the HREEs. This is consistent with a granitic source rich in Si-K-Mg-Rb-Ba-Cs-Nb-Ta-Ga-H₂O±Cr±U±CO₂. The other two corundum-bearing units show similar variations except are typically more depleted in Cu, Te, S, Rb, and Sr. Corundum δ18O analyses define a tight range between 1.49‰ and 5.3‰, with a mean of 3.2 ± 0.9‰. This suggests the interaction or mixing of meteoric water with the metasomatic fluid at some point during gem recrystallization. Worldwide ultramafic-amphibolitic gem corundum deposits show similar low δ18O, mineralogy, mineral chemistry, and local geology. This study proposes the use of amphibolite-type as an all-encompassing gem deposit model to explain several enigmatic deposits elsewhere in the world.

description: Motivated by the uniqueness problem for monostable semi-wavefronts, we propose a revised version of the Diekmann and Kaper theory of a nonlinear convolution equation. Our version of the Diekmann-Kaper theory allows 1) to consider new types of models which include nonlocal KPP type equations (with either symmetric or anisotropic dispersal), non-local lattice equations and delayed reaction-diffusion equations; 2) to incorporate the critical case (which corresponds to the slowest wavefronts) into the consideration; 3) to weaken or to remove various restrictions on kernels and nonlinearities. The results are compared with those of Schumacher (J. Reine Angew. Math. 316: 54-70, 1980), Carr and Chmaj (Proc. Amer. Math. Soc. 132: 2433-2439, 2004), and other more recent studies.

description: We study the convergence of the so-called entangled ergodic averages $\frac{1}{N^k}\sum_{n_1,...,n_k=1}^{N}T_m^{n_{α(m)}}A_{m-1}T_{m-1}^{n_{α(m-1)}}A_{m-2}...A_1T_1^{n_{α(1)}},$ where $k\leq m$ and $α:\{1,...,m\}\to\{1,...,k\}$ is a surjective map. We show that, on general Banach spaces and without any restriction on the partition $α$, the above averages converge strongly as $N\to \infty$ under some quite weak compactness assumptions on the operators $T_j$ and $A_j$. A formula for the limit based on the spectral analysis of the operators $T_j$ and the continuous version of the result are presented as well.

title: Investigating how microbiota affects amyloid-beta toxicity in C. elegans models
Creators: name: Butterfield, Emma
Publisher: name: University of Kent
Year: 2025

description: lzheimer’s disease is a progressive neurodegenerative condition and affects millions of people globally causing symptoms such as memory loss, cognitive decline, and loss of motor skills. The development of Alzheimer’s disease is linked to the deposition of amyloid beta plaques in the brain, however no effective prevention or cure exists yet. Emerging evidence suggests that microbiota may influence neurodegeneration, highlighting the potential of microbiota-based interventions, such as probiotics, in mitigating amyloid beta toxicity. However, the mechanisms contributing to this relationship are still poorly understood. This study aimed to investigate the protective effects of specific microbiota against amyloid beta toxicity using C. elegans as a model system for the development of Alzheimer’s disease therapeutics. Previous unpublished work by the Ezcurra laboratory showed Stenotrophomonas terrae (St1) and MYb57 protects against amyloid beta toxicity in GMC101 C. elegans. This study found these findings were generalisable across other strains such as C. elegans CL2006 and CL4276. To ensure there are no detrimental effects on C. elegans health by microbiota, development assays were conducted on worm length and L4 development speed when fed on different microbiota. The results showed some microbiota slightly reduced worm size and delayed L4 development, but these effects were minor and unlikely to confound aging or reproductive studies. Additionally, ~400 St1 transposon insertion mutants were generated to identify genes involved in microbial protection against Aβ toxicity, but no specific gene was isolated. 
Supplementation assays using vitamin B12 and NAC were performed due to previous studies suggesting they protect against amyloid beta toxicity [1]. However, this study was unable to replicate those findings. A C. elegans strain (unc-54p::Aβ-1-42::unc-54 3'-UTR + mtl-2p::GFP; drp-1(tm1108) IV) was created to assess whether mitochondrial fission (using drp-1) is involved in the protection given by St1 and MYb57 against amyloid beta. Whilst initial results suggest drp-1 is not the pathway responsible, further validation is needed due to limited replicates. Overall, this research provides insight into the relationship between microbiota and neurodegeneration and highlights the potential of microbiota-based interventions, such as probiotics, in preventing amyloid beta toxicity. Further research of microbiota-host interactions is crucial for developing novel therapeutic strategies for Alzheimer’s disease.

description: By following the general guiding principle that nothing should be prescribed or imposed on the universal entity, spacetime, we establish that it is the homogeneity (by which we mean homogeneity and isotropy of space and homogeneity of time) that requires not only a universally constant invariant velocity but also an invariant length given by its constant curvature, $Λ$ and spacetime is completely free of dynamics. Thus $c$ and $Λ$ are the only two true constants of the spacetime structure and no other physical constant could claim this degree of fundamentalness. When matter is introduced, the spacetime becomes inhomogeneous and dynamic, and its curvature then determines by the Bianchi differential identity the equation of motion for the Einstein gravity. The homogeneity thus demands that the natural state of \textit{free spacetime} is of constant curvature and the cosmological constant thus emerges as a clear prediction which seems to be borne out by the observations of accelerating expansion of the Universe. However it has no relation to the vacuum energy and it could be envisioned that in terms of the Planck area the Universe measures $10^{120}$ units!

We say that $\Gamma$ is normal if $G$ is a normal subgroup of ${\rm Aut}(\Gamma)$. We prove that every connected intransitive one-matching semi-Cayley graph, with maximum degree three, over a finite abelian group is normal and characterize all such nonnormal graphs.

description: Quantum computing promises to revolutionize machine learning, offering significant efficiency gains in tasks such as clustering and distance estimation. Additionally, it provides enhanced security through fundamental principles like the measurement postulate and the no-cloning theorem, enabling secure protocols such as quantum teleportation and quantum key distribution. While advancements in secure quantum machine learning are notable, the development of secure and distributed quantum analogues of kernel-based machine learning techniques remains underexplored.
 In this work, we present a novel approach for securely computing common kernels, including polynomial, radial basis function (RBF), and Laplacian kernels, when data is distributed, using quantum feature maps. Our methodology introduces a robust framework that leverages quantum teleportation to ensure secure and distributed kernel learning. The proposed architecture is validated using IBM's Qiskit Aer Simulator on various public datasets.

description: The quantum channel capacity gives the ultimate limit for the rate at which quantum data can be reliably transmitted through a noisy quantum channel. Degradable quantum channels are among the few channels whose quantum capacities are known. Given the quantum capacity of a degradable channel, it remains challenging to find a practical coding scheme which approaches capacity. Here we discuss code designs for the detected-jump channel, a degradable channel with practical relevance describing the physics of spontaneous decay of atoms with detected photon emission. We show that this channel can be used to simulate a binary classical channel with both erasures and bit-flips. The capacity of the simulated classical channel gives a lower bound on the quantum capacity of the detected-jump channel. When the jump probability is small, it almost equals the quantum capacity. Hence using a classical capacity approaching code for the simulated classical channel yields a quantum code which approaches the quantum capacity of the detected-jump channel.

description: We identify a large class of quantum many-body systems that can be solved exactly: natural frustration-free spin-1/2 nearest-neighbor Hamiltonians on arbitrary lattices. We show that the entire ground state manifold of such models can be found exactly by a tensor network of isometries acting on a space locally isomorphic to the symmetric subspace. Thus, for this wide class of models real-space renormalization can be made exact. Our findings also imply that every such frustration-free spin model satisfies an area law for the entanglement entropy of the ground state, establishing a novel large class of models for which an area law is known. Finally, we show that our approach gives rise to an ansatz class useful for the simulation of almost frustration-free models in a simple fashion, outperforming mean field theory.

Instead widely used paramagnon model we work with phenomenological spectrum of fluctuations in the orthorhombic ferromagnet with strong magnetic anisotropy. Depending of the field orientation parallel or perpendicular to the direction of spontaneous magnetization the effective amplitude of pairing interaction proves to be decreasing or increasing function of magnetic field that allows to explain the drastic difference in magnitudes of upper critical field in these directions.

description: Containerization software has been proved to be an interesting approach to facilitate the creation, deployment and run applications, reducing time-consumption tasks like, for instance, software installation, error reproducibility or software maintenance.

The DAQ software for telescopes and DUTs is an excellent candidate to be "dockerize", as it will minimize usual bottle necks in the DAQ sotware integration and development, and posterior deployment in the test beam areas.

We present an example of successful "dockerization" of the DAQ softwares for the EUTEL/AIDA telescopes and the RD53A DUT readout chips, tested during this year beam test campaigns for the Phase-II Upgrade of the CMS Inner Tracker.
Mothers of children with autism from the South Asian diaspora : the lived experiences of the home-school relationship
Creators: name: Arya, Shalini
Publisher: name: University of British Columbia
Year: 2018

description: There are a myriad of cultural factors that influence the home-school partnership for families with children with disability (Boyd & Correa, 2005; Harry, 2002; Kalyanpur, Harry, & Skrtic, 2010). South Asian families contend with community stigmas, which may prevent them from openly discussing their child’s disability and actively engaging in their child’s school (Heer, Larkin, & Rose, 2015; Ravindran & Myers, 2012; Rizvi, 2017; Zechella & Raval, 2016). Teachers and schools need to understand the best way to communicate with the families, and encourage their involvement (Welterlin & LaRue, 2007; Zhang & Bennett, 2003). Trust is an essential component to the development of a positive partnership between schools and families (Adams & Christenson, 1998; 2000). The primary objective of this research was to gain a better understanding of the school experiences of South Asian parents of children with autism spectrum disorder (autism) as well as the role of trust in their school relationships. Using qualitative methods and an Interpretive Phenomenological Analysis (IPA) approach the researcher conducted semi-structured interviews with four South Asian parents of children who have been formally designated with autism. Participants were asked to share their experiences regarding their interactions with their child’s school and what role trust played in their experiences. Findings indicate that South Asian parents tend to have an innate trust with schools and teachers. As they interact with their child’s teacher and the school system, the frequency and severity of their positive and negative experiences impact their level of trust. Differences in experience relate to the differences in each participant’s contextually bound lifeworld.
Exact analysis of disentanglement for continuous variable systems and application to a two-body system at zero temperature in an arbitrary heat bath

description: We outline an exact approach to decoherence and entanglement problems for continuous variable systems. The method is based on a construction of quantum distribution functions introduced by Ford and Lewis \cite{ford86} in which a system in thermal equilibrium is placed in an initial state by a measurement and then sampled by subsequent measurements. With the Langevin equation describing quantum Brownian motion, this method has proved to be a powerful tool for discussing such problems. After reviewing our previous work on decoherence and our recent work on disentanglement, we apply the method to the problem of a pair of particles in a correlated Gaussian state. The initial state and its time development are explicitly exhibited. For a single relaxation time bath at zero temperature exact numerical results are given. The criterion of Duan et al. \cite{duan00} for such states is used to prove that the state is initially entangled and becomes separable after a finite time (entanglement sudden death).

description: Current models of health care do not meet the needs of the 22% of Australian children living in housing instability/homelessness. These children have poorer access to health services and appointment compliance, increased Emergency Department (ED) utilisation, and overall poorer mental and physical health outcomes. An embedded, Nurse Practitioner(NP) model of care for disadvantaged/vulnerable children will lead to enhanced access to health care and increased uptake of referrals leading to improved health outcomes. The project findings will be translated to health service decision makers to inform more appropriate models of health delivery for homeless children currently missing out on urgent acute care.

description: Reversible circuits have applications in digital signal processing, computer graphics, quantum computation and cryptography. In this paper, a generalized k*k reversible gate family is proposed and a 3*3 gate of the family is discussed. Inverter, AND, OR, NAND, NOR, and EXOR gates can be realized by this gate. Implementation of a full-adder circuit using two such 3*3 gates is given. This full-adder circuit contains only two reversible gates and produces no extra garbage outputs. The proposed full-adder circuit is efficient in terms of gate count, garbage outputs and quantum cost. A 4-bit carry skip adder is designed using this full-adder circuit and a variable block carry skip adder is discussed. Necessary equations required to evaluate these adder are presented.

description: If supersymmetry turns out to be a symmetry of nature at low energies, the first order of business to measure the soft breaking parameters. But one will also want to understand the symmetry, and its breaking, more microscopically. Two aspects of this problem constitute the focus of these lectures. First, what sorts of dynamics might account for supersymmetry breaking, and its manifestation at low energies. Second, how might these features fit into string theory (or whatever might be the underlying theory in the ultraviolet). The last few years have seen a much improved understanding of the first set of questions, and at least a possible pathway to address the second.

Bethe lattice solution of a model of SAW's with up to 3 monomers per site and no restriction

description: In the multiple monomers per site (MMS) model, polymeric chains are represented by walks on a lattice which may visit each site up to K times. We have solved the unrestricted version of this model, where immediate reversals of the walks are allowed (RA) for K = 3 on a Bethe lattice with arbitrary coordination number in the grand-canonical formalism. We found transitions between a non-polymerized and two polymerized phases, which may be continuous or discontinuous. In the canonical situation, the transitions between the extended and the collapsed polymeric phases are always continuous. The transition line is partly composed by tricritical points and partially by critical endpoints, both lines meeting at a multicritical point. In the subspace of the parameter space where the model is related to SASAW's (self-attracting self-avoiding walks), the collapse transition is tricritical. We discuss the relation of our results with simulations and previous Bethe and Husimi lattice calculations for the MMS model found in the literature.

description: We present the first search for pair production of isolated jets of charged leptons in association with a large imbalance in transverse energy in ppbar collisions using 5.8 fb^-1 of integrated luminosity collected by the D0 detector at the Fermilab Tevatron Collider. No excess is observed above Standard Model background, and the result is used to set upper limits on the production cross section of pairs of supersymmetric chargino and neutralino particles as a function of "dark-photon" mass, where the dark photon is produced in the decay of the lightest supersymmetric particle.

description: The enactment of Restrictions on Community Activities or PPKM is currently a topic that is always awaited by the people of Indonesia at the end of each implementation period. The discussion was also widely carried out on Twitter by including the hashtag #PPKM. The research is intended to be able to understand topics covered by Twitter users with hashtags #PPKM as well as using SMB and LDA. To determine the optimal number of topics is done by looking at the value of perplexity and coherence topics. Based on the data obtained, the author found several topics that became the main point of discussion. Among others is PPKM itself, then followed by the word 'udh' in this case is to do vaccinations, to polairud as a free vaccination organizer.
Airfoil Synchronous Surging and Pitching

description: Combined pitching-and-surging of an airfoil at the identical frequency (i.e., synchronously), at four different phase-differences, was investigated theoretically and experimentally. The most general unsteady theoretical formulation was adopted to calculate the lift coefficient, and then extended to explicitly compute the unsteady bound vortex sheet. This was used for comparison to experiments and facilitated the computation of both Joukowsky and impulsive-pressure lift contributions. Experiments were performed using a NACA 0018 airfoil in an unsteady wind tunnel at an average Reynolds number of $3.0 \times 10^5$, with a free-stream oscillation amplitude of 0.51, an angle-of-attack range of $2^\circ \pm 2^\circ$, and a reduced frequency of 0.097. In general, excellent correspondence was observed between theory and experiment, representing the first direct experimental validation of the general theory. It was shown, both theoretically and experimentally, that the lift coefficient was not accurately represented by independent superposition of surging and pitching effects, due to variations in the instantaneous effective reduced frequency not accounted for during pure pitching. Deviations from theory, observed at phase-lags of $90^\circ$ and $180^\circ$ were attributed to bursting of separation bubbles during the early stages of the acceleration phase. The largest deviations occurred when the impulsive-pressure lift contribution was small relative to the Joukowsky contribution, because the latter was most affected by bubble-bursting. Bubble-bursting resulted in large form-drag oscillations that occurred at identical phase angles within the oscillation cycle, irrespective of the phase difference between surging and pitching, as well as in the absence of pitching. The bubble-bursting dynamic stall mechanism may have important implications for rotor performance and noise emissions.

description: We study the coherence and density modulation of a non-equilibrium exciton-polariton condensate in a one-dimensional valley with disorder. By means of interferometric measurements we evidence a modulation of the first-order coherence function and we relate it to a disorder-induced modulation of the condensate density, that increases as the pump power is increased. The non-monotonous spatial coherence function is found to be the result of the strong non-equilibrium character of the one-dimensional system, in the presence of disorder.

description: We present a preliminary analysis of the small-scale structure found in new 70-520 micron continuum maps of the Rosette molecular cloud (RMC), obtained with the SPIRE and PACS instruments of the Herschel Space Observatory. We find 473 clumps within the RMC using a new structure identification algorithm, with sizes up to ~1.0 pc in diameter. A comparison with recent Spitzer maps reveals that 371 clumps are "starless" (without an associated young stellar object), while 102 are "protostellar." Using the respective values of dust temperature, we determine the clumps have masses (M_C) over the range -0.75 <= log (M_C/M_sun) <= 2.50. Linear fits to the high-mass tails of the resulting clump mass spectra (CMS) have slopes that are consistent with those found for high-mass clumps identified in CO emission by other groups.
