New approaches to target cellular senescence for the amelioration of age-related pathologies.

description: Aging has been broadly defined as a functional decline that progresses with time and leads to impaired function and increased vulnerability to death. Cellular senescence is one of the main factors involved in this age-related functional decline and it has been shown that the percentage of senescent cells in tissues increases with age in different organs and in age-related disorders. Therefore, cellular senescence has been characterized as one of the hallmarks of aging. Consistent with this, elimination of senescent cells could ameliorate the negative effects of ageing, as it has already been shown in mouse models. However, the currently available methods of targeting and eliminating senescent cells lack specificity and have off-target effects. The first barrier that slows the development of anti-senescent drugs is lack of specific markers for senescence. To overcome this issue, we validated VPS26A, EBP50 and PLD3, which were recently identified in a screen of proteins specifically upregulated in senescent cells. Moreover, we propose novel approaches to target and eliminate senescent cells. Our first approach is an Antibody Drug Conjugates that specifically identifies and directly eliminates senescent cells through a marker expressed in their plasma membrane. Second, we used senoblocking, a strategy that aims to block cellular senescence before it occurs. For that purpose, we treated a progeroid mouse model with Ibrutinib, a clinically available BTK inhibitor. It has been previously hown that BTK inhibition interrupts cellular senescence. The treatment resulted in an improvement of healthspan and protection of a decline in brain and skeletal muscle performance. The third approach tested relied on the combinations of BCL-XL inhibitors, A1331852 and 9-hydroxyellipiticine, that synergistically kill senescent cells. The results from our research introduce novel promising therapeutic interventions for the elimination of senescent cells which could find a translational application in the future.

description: We prove that the category of left-handed strongly distributive skew lattices with zero and proper homomorphisms is dually equivalent to a category of sheaves over local Priestley spaces. Our result thus provides a non-commutative version of classical Priestley duality for distributive lattices and generalizes the recent development of Stone duality for skew Boolean algebras. From the point of view of skew lattices, Leech showed early on that any strongly distributive skew lattice can be embedded in the skew lattice of partial functions on some set with the operations being given by restriction and so-called override. Our duality shows that there is a canonical choice for this embedding. Conversely, from the point of view of sheaves over Boolean spaces, our results show that skew lattices correspond to Priestley orders on these spaces and that skew lattice structures are naturally appropriate in any setting involving sheaves over Priestley spaces.

description: We compare two approaches to compute a portion of the spectrum of dense symmetric definite generalized eigenproblems: one is based on the reduction to tridiagonal form, and the other on the Krylov-subspace iteration. Two large-scale applications, arising in molecular dynamics and material science, are employed to investigate the contributions of the application, architecture, and parallelism of the method to the performance of the solvers. The experimental results on a state-of-the-art 8-core platform, equipped with a graphics processing unit (GPU), reveal that in real applications, iterative Krylov-subspace methods can be a competitive approach also for the solution of dense problems.

title: Leveraging Artificial Intelligence and Machine Learning for Enhanced Cybersecurity: A Proposal to Defeat Malware
Creators: name: Boateng, Emmanuel
Publisher: name: Old Dominion University Libraries
Year: 2023

description: Cybersecurity is very crucial in the digital age in order to safeguard the availability, confidentiality, and integrity of data and systems. Mitigation techniques used in the industry include Multi-factor Authentication (MFA), Incident Response Planning (IRP), Security Information and Event Management (SIEM), and Signature-based and Heuristic Detection.

MFA is employed as an additional layer of protection in several sectors to help prevent unauthorized access to sensitive data. IRP is a plan in place to address cybersecurity problems efficiently and expeditiously. SIEM offers real-time analysis and alerts the system of threats and vulnerabilities. Heuristic-based detection relies on detecting anomalies when it comes to the behavior of files and domains, whereas signature-based detection uses predefined malware codes and known signatures to help identify malware.

Artificial intelligence along with machine learning could enhance cyber detection and response by utilizing a vast amount of data and algorithms to help identify trends, make predictions, and take actions without human supervision. This paper discusses how this proposal can be accomplished and could help defeat malware.

description: Four estimators of the directed information rate between a pair of jointly stationary ergodic finite-alphabet processes are proposed, based on universal probability assignments. The first one is a Shannon--McMillan--Breiman type estimator, similar to those used by Verdú (2005) and Cai, Kulkarni, and Verdú (2006) for estimation of other information measures. We show the almost sure and $L_1$ convergence properties of the estimator for any underlying universal probability assignment. The other three estimators map universal probability assignments to different functionals, each exhibiting relative merits such as smoothness, nonnegativity, and boundedness. We establish the consistency of these estimators in almost sure and $L_1$ senses, and derive near-optimal rates of convergence in the minimax sense under mild conditions. These estimators carry over directly to estimating other information measures of stationary ergodic finite-alphabet processes, such as entropy rate and mutual information rate, with near-optimal performance and provide alternatives to classical approaches in the existing literature. Guided by these theoretical results, the proposed estimators are implemented using the context-tree weighting algorithm as the universal probability assignment. Experiments on synthetic and real data are presented, demonstrating the potential of the proposed schemes in practice and the utility of directed information estimation in detecting and measuring causal influence and delay.

description: The lethal heat treatment dose (time and temperature) for the pre-pupal life stage of Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), emerald ash borer, was determined through an in vitro application using a carefully calibrated heat treatment apparatus. The lethal and sublethal effects of heat on A. planipennis prepupae were assessed through a ramped heat delivery application, simulating industrial kilns and conventional heat chamber operations, for treatments combining target temperatures of 54 °C, 55 °C, and 56 °C, and exposure durations of 0 min (i.e., kiln temperature ramp only), 15 min, or 30 min. Prepupal emerald ash borer larvae did not survive exposure to 56 °C for 15 min or longer, or to 55 °C for 30 min. Sublethal effects were observed for all other treatments. Sublethal effects included delayed development and failure to complete the pupal and adult life stages. The datasets and associated R statistical computing langauge code are deposited here.

description: The data are observations on post-treatment survival of emerald ash borer larvae exposed to heat in a water bath. The experiments were used to determine the optimal heating conditions for treatment of wood infested with the insect. The insects were exposed to one of three temperatures (54, 55 or 56 C) for a set period (0, 15 or 30 minutes) and then, along with unexposed control insects, were observed to determine if they died or transitioned to the next stage of development (i.e., pupated).  The data were analysed with survival models to determine if temperature and duration of treatment had an effect on survival and the probability of pupating. Insects were observed every 24-72 h, pretreatment weight was also determined.

description: The factorization theorem for exclusive processes in perturbative QCD predicts the behavior of the pion electromagnetic form factor $F(t)$ at asymptotic spacelike momenta $t(=-Q^2)<0$. We address the question of the onset energy using a suitable mathematical framework of analytic continuation, which uses as input the phase of the form factor below the first inelastic threshold, known with great precision through the Fermi-Watson theorem from $ππ$ elastic scattering, and the modulus measured from threshold up to 3 GeV by the BaBar Collaboration. The method leads to almost model-independent upper and lower bounds on the spacelike form factor. Further inclusion of the value of the charge radius and the experimental value at $-2.45 \gev^2$ measured at JLab considerably increases the strength of the bounds in the region $ Q^2 \lesssim 10 \gev^2$, excluding the onset of the asymptotic perturbative QCD regime for $Q^2< 7\gev^2$. We also compare the bounds with available experimental data and with several theoretical models proposed for the low and intermediate spacelike region.

description: We obtain a tight distribution-specific characterization of the sample complexity of large-margin classification with L2 regularization: We introduce the margin-adapted dimension, which is a simple function of the second order statistics of the data distribution, and show distribution-specific upper and lower bounds on the sample complexity, both governed by the margin-adapted dimension of the data distribution. The upper bounds are universal, and the lower bounds hold for the rich family of sub-Gaussian distributions with independent features. We conclude that this new quantity tightly characterizes the true sample complexity of large-margin classification. To prove the lower bound, we develop several new tools of independent interest. These include new connections between shattering and hardness of learning, new properties of shattering with linear classifiers, and a new lower bound on the smallest eigenvalue of a random Gram matrix generated by sub-Gaussian variables. Our results can be used to quantitatively compare large margin learning to other learning rules, and to improve the effectiveness of methods that use sample complexity bounds, such as active learning.

description: Aims. We present our re-analyze the Kepler photometric dataset, searching for planetary transits using an alternative processing pipeline to the one used by the Kepler Mission. Methods. The SARS pipeline was tested extensively by processing all available CoRoT data. We used this pipeline to search for (additional) planetary transits only in the Kepler objects of interest (KOIs). Results. Although less than 1% of the Kepler dataset are KOIs we are able to significantly update the overall statistics of planetary multiplicity: we find 84 new transit signals on 64 systems on these light curves only, nearly doubling the number of transit signals in these systems. Forty-one of the systems were singly-transiting systems that are now multiply-transiting. Notable among the new discoveries are KOI 435 as a new six-candidate system (of which kind only Kepler-11 was known before), KOI 277 (which includes two candidates in a 6:7 resonance and anti-correlated transit timing variations) - all but validating the system, KOIs 719, 1574, and 1871 that have small planet candidates (1.15, 2.05 and 1.71R_Earth) in the habitable zone of their host star, and KOI 1843 that exhibits the shortest period (4.25hr) and among the smallest (0.63 R_Earth) of all planet candidates. We are also able to reject 11 KOIs as eclipsing binaries, update the ephemeris for five KOIs and otherwise discuss yet other objects. Interestingly, about 1/3 of the newly detected candidates participate in period commensurabilities. Finally, we discuss the possible overestimation of parameter errors in the current list of KOIs. Conclusions. Our results strengthen previous analyses of the multi-transiting ensemble. Nevertheless, we conclude that despite the phenomenal success of the Kepler mission, parallel analysis of the data by multiple teams is required to make full use of the data. [ABRIDGED]

description: There is a conjecture in the literature that indicates the tree-level S-matrix elements of graviton become symmetric under the $SL(2,Z)$ transformation after including the loops and the nonperturbative effects. Using the Ward identity corresponding to the global S-duality transformations, this conjecture can be extended to other S-matrix elements as well. While the $SL(2,Z)$ transformation on the background dilaton is nonlinear, the Ward identity dictates the S-duality transformations on external states should be the linearized $SL(2,R)$ transformations. We examine in details various S-matrix elements involving massless closed string and/or open string vertex operators on the world volume of D$_3$-brane in favor of this conjecture.

description: Weyl's formulation of quantum mechanics opened the possibility of studying the dynamics of quantum systems both in infinite-dimensional and finite-dimensional systems. Based on Weyl's approach, generalized by Schwinger, a self-consistent theoretical framework describing physical systems characterised by a finite-dimensional space of states has been created. The used mathematical formalism is further developed by adding finite-dimensional versions of some notions and results from the continuous case. Discrete versions of the continuous Gaussian functions have been defined by using the Jacobi theta functions. We continue the investigation of the properties of these finite Gaussians by following the analogy with the continuous case. We study the uncertainty relation of finite Gaussian states, the form of the associated Wigner quasi-distribution and the evolution under free-particle and quantum harmonic oscillator Hamiltonians. In all cases, a particular emphasis is put on the recovery of the known continuous-limit results when the dimension $d$ of the system increases.

description: We show that holographic renormalization of relativistic gravity in asymptotically Lifshitz spacetimes naturally reproduces the structure of gravity with anisotropic scaling: The holographic counterterms induced near anisotropic infinity take the form of the action for gravity at a Lifshitz point, with the appropriate value of the dynamical critical exponent $z$. In the particular case of 3+1 bulk dimensions and $z=2$ asymptotic scaling near infinity, we find a logarithmic counterterm, related to anisotropic Weyl anomaly of the dual CFT, and show that this counterterm reproduces precisely the action of conformal gravity at a $z=2$ Lifshitz point in 2+1 dimensions, which enjoys anisotropic local Weyl invariance and satisfies the detailed balance condition. We explain how the detailed balance is a consequence of relations among holographic counterterms, and point out that a similar relation holds in the relativistic case of holography in $AdS_5$. Upon analytic continuation, analogous to the relativistic case studied recently by Maldacena, the action of conformal gravity at the $z=2$ Lifshitz point features in the ground-state wavefunction of a gravitational system with an interesting type of spatial anisotropy.

description: Der russische Angriffskrieg auf die Ukraine hat eine große Fluchtbewegung ausgelöst. Allein nach Deutschland sind seit Kriegsbeginn über eine Million Menschen gekommen. Auf Grundlage der zweiten Befragungswelle der Studie „Geflüchtete aus der Ukraine in Deutschland (IAB-BiB/ FReDA-BAMF-SOEP-Befragung)“ zeigt sich, dass zu Beginn des Jahres 2023 ein zunehmender Anteil der ukrainischen Geflüchteten beabsichtigt längerfristig in Deutschland zu bleiben. Rund drei Viertel haben eine private Unterkunft gefunden, ein ähnlich großer Anteil hat bereits an Deutschkursen teilgenommen oder ist aktuell noch dabei. 18 Prozent der 18- bis 64-Jährigen gehen einer Erwerbstätigkeit nach – von den anderen wollen dies über zwei Drittel sofort oder innerhalb des kommenden Jahres tun. Während fast alle geflüchteten Kinder und Jugendlichen im schulpflichtigen Alter eine allgemein- oder berufsbildende Schule in Deutschland besuchen, sind nur rund sechs von zehn Kindern zwischen drei und sechs Jahren in einer Kindertagesbetreuung (KiTa). Zur Stärkung der gesellschaftlichen Teilhabe und angesichts des hohen Anteils von Müttern unter den Geflüchteten sollten insbesondere Möglichkeiten zur Kinderbetreuung verbessert werden, um unter anderem die Teilnahme an Integrations-und Sprachkursen und den Weg in Beschäftigung zu erleichtern. Zudem ist es zentral, schnell eine Entscheidung über die Verlängerung des bis zum März 2024 befristeten Aufenthaltsrechts herbeizuführen und damit Rechts- und Planungssicherheit zu schaffen.

description: The anomalous Hall effect in a multiband tight-binding model is numerically studied taking into account both elastic scattering by disorder and inelastic scattering by the electron-phonon interaction. The Hall conductivity is obtained as a function of temperature $T$, inelastic scattering rate $γ$, chemical potential $μ$, and impurity concentration $x_{\rm imp}$. We find that the new scaling law holds over a wide range of these parameters; $-σ_{xy}= (ασ_{xx0}^{-1} + βσ_{xx0}^{-2}) σ_{xx}^2 + b$, with $σ_{μν}$ ($σ_{μν0}$) being the conductivity tensor (with only elastic scattering), which corresponds to the recent experimental observation [Phys. Rev. Lett. {\bf 103} (2009) 087206]. The condition of this scaling is examined. Also, it is found that the intrinsic mechanism depends on temperature under a resonance condition.

description: of the profession of Physical Education and School Sport (PESS); the City of London had been awarded the XXX Olympiad. The political rhetoric during this moment in England’s PESS history required a directional polity that created a legacy culture. The research analysed political documentation from 2005–2015. This data consisted of Hansard transcripts from parliamentary chambers and reports by the Department for Culture, Media and Sport (DCMS), the Department for Education (DfE) and the London Organising Committee Olympic Games (LOCOG). 21 sampled documents producing data sources of 260,000 words were divided into three phases of before, during and after the London 2012 Olympic Games (L2012OG). Analytical frameworks were shaped by Fisher’s (2004) adapted comparative cultural model and the thematic analysis of soft legacy (SL) variables were coded using NVivo 12 software so that the volume and diversity of the materials studied could be comprehended.Findings illustrate that the L2012OG shares within parliament were significantly different to what was published in governmental policies. SL priorities within education were consistently marginalised and statutory expectations were missing. The delay in the publication of key educational materials was a critical error, hence between 2005-2015 professionals struggled to ‘create a world-class PE’ (Olympic Minister, Jowell, HC, vol. 490, 2009). Conclusions illustrate that far more understanding within research should come from the narratives within parliament. Assumptions about political narratives must be viewed through the lens of truth on what, when and who is debating key decisions in education, health and well-being activities. This research demonstrates that the failings of the SL within education were because considerations made in parliamentary chambers were too late or not fully embraced.

description: We present calculations of axial-current matrix elements between various heavy-meson and heavy-baryon states to the next-to-leading order in heavy hadron chiral perturbation theory in the p-regime. When compared with data from lattice computations or experiments, these results can be used to determine the axial couplings in the chiral Lagrangian. Our calculation is performed in partially-quenched chiral perturbation theory for both SU(4|2) and SU(6|3). We incorporate finite-size effects arising from a single Goldstone meson wrapping around the spatial volume. Results for full QCD with two and three flavours can be obtained straightforwardly by taking the sea-quark masses to be equal to the valence-quark masses. To illustrate the impact of our chiral perturbation theory calculation on lattice computations, we analyse the SU(2) full QCD results in detail. We also study one-loop contributions relevant to the heavy hadron strong-decay amplitudes involving final-state Goldstone bosons, and demonstrate that the quark-mass dependence of these amplitudes can be significantly different from that of the axial current matrix elements containing only single hadron external states.

description: We experimentally demonstrate polarization entanglement for squeezed vacuum pulses containing more than 10^5 photons. We also study photon-number entanglement by calculating the Schmidt number and measuring its operational counterpart. Theoretically, our pulses are the more entangled the brighter they are. This promises important applications in quantum technologies, especially photonic quantum gates and quantum memories.

A comparison of the galaxy peculiar velocity field with the PSCz gravity field-- A Bayesian hyper-parameter method

description: We constructed a Bayesian hyper-parameter statistical method to quantify the difference between predicted velocities derived from the observed galaxy distribution in the \textit{IRAS}-PSC$z$ redshift survey and peculiar velocities measured using different distance indicators. In our analysis we find that the model--data comparison becomes unreliable beyond $70 \hmpc$ because of the inadequate sampling by \textit{IRAS} survey of prominent, distant superclusters, like the Shapley Concentration. On the other hand, the analysis of the velocity residuals show that the PSC$z$ gravity field provides an adequate model to the local, $\le 70 \hmpc$, peculiar velocity field. The hyper-parameter combination of ENEAR, SN, A1SN and SFI++ catalogues in the Bayesian framework constrains the amplitude of the linear flow to be $β=0.53 \pm 0.014$. For an rms density fluctuations in the PSC$z$ galaxy number density $σ_8^{\rm gal}=0.42\pm0.03$, we obtain an estimate of the growth rate of density fluctuations $fσ_{8}(z\sim0) = 0.42 \pm 0.033$, which is in excellent agreement with independent estimates based on different techniques.

Affine actions on non-archimedean trees

subject: 20E08, 20F65

description: We initiate the study of affine actions of groups on $Λ$-trees for a general ordered abelian group $Λ$; these are actions by dilations rather than isometries. This gives a common generalisation of isometric action on a $Λ$-tree, and affine action on an $\R$-tree as studied by I. Liousse. The duality between based length functions and actions on $Λ$-trees is generalised to this setting. We are led to consider a new class of groups: those that admit a free affine action on a $Λ$-tree for some $Λ$. Examples of such groups are presented, including soluble Baumslag-Solitar groups and the discrete Heisenberg group.

description: Das umfangreiche Sammeln persönlicher Daten im Internet hat in den letzten zwei Jahrzehnten einen großen Markt für personalisierte Inhalte ermöglicht. Tausende kleine und große Unternehmen arbeiten an der Sammlung und Zusammenführung von Daten über das Nutzer*innenverhalten auf Websites, um über Eigenschaften und -Interessen von Nutzer*innen zu lernen. Ganz an der Spitze befinden sich digitale Unternehmen wie Alphabet (Google), Amazon und Meta (Facebook), die den Großteil ihrer Umsätze durch Online-Werbung erwirtschaften. Diese Studie zeigt empirisch, dass eine steigende Menge an Daten zu einer besseren Vorhersagequalität von Personenmerkmalen führt, die für personalisierte Inhalte essenziell sind. Dennoch nehmen die Verbesserungen der Vorhersagequalität ab. Je mehr Daten dazukommen, desto weniger zusätzlichen Nutzen haben sie. Man kann hier von abnehmenden Skalenerträgen sprechen. Google, was bisher Klick-gewichtet auf über 80 Prozent der gängigsten Websites Nutzer*innenverhalten beobachten konnte, erreichte, bei gleichzeitig steigenden Nutzer*innenzahlen und beobachteten Websitebesuchen, jedoch signifikant weniger stark abnehmende Skalenerträge als seine Wettbewerber. Wenn aber Google allein von weiteren Daten durchweg mehr profitieren kann als seine Wettbewerber, können selbst innovative kleinere Unternehmen mangels Daten nur geringe Chancen haben, konkurrenzfähige Produkte zu vermarkten. Es würde sich eine uneinholbare Marktposition für den Google-Konzern ergeben, was zu Nachteilen für Konsument*innen führt.
