description: This work classifies the set of diagonal gates that can implement a single or two-qubit transversal logical gate for qubit stabilizer codes. We show that individual physical gates on the underlying qubits that compose the code are restricted to have entries of the form $e^{i πc/2^k}$ along their diagonal, resulting in a similarly restricted class of logical gates that can be implemented in this manner. Moreover, we show that all diagonal logical gates that can be implemented transversally by individual physical diagonal gates must belong to the Clifford hierarchy. Furthermore, we can use this result to prove a conjecture about transversal gates made by Zeng et al. in 2007.

description: MicroRNAs (miRNAs) are small, noncoding RNAs that post-transcriptionally regulate gene expression. An emerging mechanism to control miRNA production is the addition of an oligo-uridine tail to the 3′ end of the precursor miRNA. This has been demonstrated for the Let-7 family of miRNAs in embryonic cells. Additionally, nontemplated nucleotides have been found on mature miRNA species, though in most cases it is not known if nucleotide addition occurs at the precursor step or at the mature miRNA. To examine the diversity of nucleotide addition we have developed a high-throughput sequencing method specific for miRNA precursors. Here we report that nontemplated addition is a widespread phenomenon occurring in many miRNA families. As previously reported, Let-7 family members are oligo-uridylated in embryonic cells in a Lin28-dependent manner. However, we find that the fraction of uridylated precursors increases with differentiation, independent of Lin28, and is highest in adult mouse tissues, exceeding 30% of all sequence reads for some Let-7 family members. A similar fraction of sequence reads are modified for many other miRNA families. Mono-uridylation is most common, with cytidine and adenosine modification less frequent but occurring above the expected error rate for Illumina sequencing. Nucleotide addition in cell lines is associated with 3′ end degradation, in contrast to adult tissues, where modification occurs predominantly on full-length precursors. This work provides an unprecedented view of the complexity of 3′ modification and trimming of miRNA precursors.

description: O objetivo foi mostrar como a interdisciplinaridade é percebida por trabalhadores e usuários de três unidades de saúde com estratégias de atendimento diferentes: Saúde da Família, Saúde Básica (tradicional) e Atenção Especializada em Odontologia. A metodologia empregada foi questionário, submetido à análise qualitativa hermenêutica dialética1. Para os trabalhadores, foram identificados diversos resultados interessantes sobre o tema: falta de noção da necessidade de trocar informações em equipe; aproveitar reuniões de equipe para discutir assuntos não relacionados aos casos clínicos; capacitação melhora relacionamento em equipe (diminui inseguranças); trocar informações em equipe multidisciplinar pode transformá-la em interdisciplinar; fortalecer sentimento de pertencimento é importante para interdisciplinaridade. Dialogar, tolerar, respeitar, ouvir, ser flexível e enxergar além de si; conhecer os resultados das decisões em equipe e corresponsabilizar também foram destaque para valorização do trabalho interdisciplinar. Em relação à percepção dos usuários dos serviços, os resultados encontrados foram: maioria não participa de grupos educativos desenvolvidos a partir de iniciativas multidisciplinares; usuários apreciam e valorizam o atendimento realizado por mais de um profissional, mas não sugerem nenhum modo disso ser feito quando são convidados a tomar parte da organização. Conclusões: interdisciplinaridade favorece relação equipe-usuário, diminui espera, aumenta resolução, mas a visão curativista do usuário ainda é prevalente sobre a educativa. 79 Acolhimento independe da ação interdisciplinar. Em uma das unidades, interdisciplinaridade prescindiu de reuniões de equipe para ocorrer.

description: Phonon softening is a ubiquitous phenomenon in condensed matter systems which is often associated with charge density wave (CDW) instabilities and anharmonicity. The interplay between phonon softening, CDW and superconductivity is a topic of intense debate. In this work, the effects of anomalous soft phonon instabilities on superconductivity are studied based on a recently developed theoretical framework that accounts for phonon damping and softening within the Migdal-Eliashberg theory. Model calculations show that the phonon softening in the form of a sharp dip in the phonon dispersion relation, either acoustic or optical (including the case of Kohn-type anomalies typically associated with CDW), can cause a manifold increase of the electron-phonon coupling constant $λ$. This, under certain conditions, which are consistent with the concept of optimal frequency introduced by Bergmann and Rainer, can produce a large increase of the superconducting transition temperature $T_c$. In summary, our results suggest the possibility of reaching high-temperature superconductivity by exploiting soft phonon anomalies restricted in momentum space.

Maximum Entropy Principle and the Higgs Boson Mass

description: A successful connection between Higgs boson decays and the Maximum Entropy Principle is presented. Based on the information theory inference approach we determine the Higgs boson mass as $M_H= 125.04\pm 0.25$ GeV, a value fully compatible to the LHC measurement. This is straightforwardly obtained by taking the Higgs boson branching ratios as the target probability distributions of the inference, without any extra assumptions beyond the Standard Model. Yet, the principle can be a powerful tool in the construction of any model affecting the Higgs sector. We give, as an example, the case where the Higgs boson has an extra invisible decay channel. Our findings suggest that a system of Higgs bosons undergoing a collective decay to Standard Model particles is among the most fundamental ones where the Maximum Entropy Principle applies.

description: Social media is being increasingly weaponized by state-backed actors to elicit reactions, push narratives and sway public opinion. These are known as Information Operations (IO). The covert nature of IO makes their detection difficult. This is further amplified by missing data due to the user and content removal and privacy requirements. This work advances the hypothesis that the very reactions that Information Operations seek to elicit within the target social systems can be used to detect them. We propose an Interval-censored Transformer Hawkes (IC-TH) architecture and a novel data encoding scheme to account for both observed and missing data. We derive a novel log-likelihood function that we deploy together with a contrastive learning procedure. We showcase the performance of IC-TH on three real-world Twitter datasets and two learning tasks: future popularity prediction and item category prediction. The latter is particularly significant. Using the retweeting timing and patterns solely, we can predict the category of YouTube videos, guess whether news publishers are reputable or controversial and, most importantly, identify state-backed IO agent accounts. Additional qualitative investigations uncover that the automatically discovered clusters of Russian-backed agents appear to coordinate their behavior, activating simultaneously to push specific narratives.

description: A wave propagating through a scattering medium typically yields a complex temporal field distribution. Over the years, a number of procedures have emerged to shape the temporal profile of the field in order to temporally focus its energy on a receiver. By analogy, we theoretically and experimentally demonstrate here how to maximize the total Fisher information transmitted to a receiver, and how to focus the Fisher information at any given time. This enables one to estimate the value of any physical observable with optimal precision from noisy measurements, as experimentally illustrated using acoustic waves in the ultrasound regime. By yielding the ultimate precision limit achievable from time-resolved measurements performed in arbitrarily complex media, our approach sets a general benchmark for many applications such as structural health monitoring and biomedical imaging.

description: The ring structures that appear in Au+Au collisions at collision energies $\sqrt{s_{NN}}=$ 3 -- 30 GeV are studied. The calculations are performed within the model of three-fluid dynamics. It is demonstrated that a pare of vortex rings are formed, one at forward and another at backward rapidities, in ultra-central Au+Au collisions at $\sqrt{s_{NN}}>$ 4 GeV. The vortex rings carry information about early stage of the collision, in particular about the stopping of baryons. It is shown that these rings can be detected by measuring the ring observable $R_Λ$ even in rapidity range $0

description: We present a coarse-grained two dimensional mechanical model for the microtubule-tau bundles in neuronal axons in which we remove taus, as can happen in various neurodegenerative conditions such as Alzheimer's disease, tauopathies, and chronic traumatic encephalopathy. Our simplified model includes (i) taus modeled as entropic springs between microtubules, (ii) removal of taus from the bundles due to phosphorylation, and (iii) a possible depletion force between microtubules due to these dissociated phosphorylated taus. We equilibrate upon tau removal using steepest descent relaxation. In the absence of the depletion force, the transverse rigidity to radial compression of the bundle falls to zero at about 60% tau occupancy, in agreement with standard percolation theory results. However, with the attractive depletion force, spring removal leads to a first order collapse of the bundles over a wide range of tau occupancies for physiologically realizable conditions. While our simplest calculations assume a constant concentration of microtubule intercalants to mediate the depletion force, including a dependence that is linear in the detached taus yields the same collapse. Applying percolation theory to removal of taus at microtubule tips, which are likely to be the protective sites against dynamic instability, we argue that the microtubule instability can only obtain at low tau occupancy, from 0.06-0.30 depending upon the tau coordination at the microtubule tips. Hence, the collapse we discover is likely to be more robust over a wide range of tau occupancies than the dynamic instability. We suggest in vitro tests of our predicted collapse.

description: We compute the probability of producing $n$ particles from few colliding particles in the unbroken $(3+1)$-dimensional $λϕ^4$ theory. To this end we numerically implement semiclassical method of singular solutions which works at ${n \gg 1}$ in the weakly coupled regime ${λ\ll 1}$. For the first time, we obtain reliable results in the region of exceptionally large final state multiplicities ${n\gg λ^{-1}}$ where the probability decreases exponentially with $n$, ${{\cal P}(\mbox{few} \to n) \sim \exp\{f_\infty(\varepsilon) \, n\}}$, and its slope $f_{\infty}< 0$ depends on the mean kinetic energy $\varepsilon$ of produced particles. In the opposite case ${n\ll λ^{-1}}$ our data match well-known tree-level result, and they interpolate between the two limits at $n \sim λ^{-1}$. Overall, this proves exponential suppression of the multiparticle production probability at ${n\gg 1}$ and arbitrary $\varepsilon$ in the unbroken theory. Using numerical solutions, we critically analyze the mechanism for multiple Higgs boson production suggested in the literature. Application of our technique to the scalar theory with spontaneously broken symmetry can eradicate (or confirm) it in the nearest future.

description: Weak line emission originating in the photosphere is well known from O stars and widely used for luminosity classification. The physical origin of the line emission are NLTE effects, most often optical pumping by far-UV lines. Analogous lines in B stars of lower luminosity are identified in radially pulsating $β$ Cephei stars. Their diagnostic value is shown for radially pulsating stars, as these lines probe a much larger range of the photosphere than absorption lines, and can be traced to regions where the pulsation amplitude is much lower than seen in the absorption lines.

description: Metazoan replication-dependent histone mRNAs are the only nonpolyadenylated cellular mRNAs. Formation of the histone mRNA 3′ end requires the U7 snRNP, which contains Lsm10 and Lsm11, and FLASH, a processing factor that binds Lsm11. Here, we identify sequences in Drosophila FLASH (dFLASH) that bind Drosophila Lsm11 (dLsm11), allow localization of dFLASH to the nucleus and histone locus body (HLB), and participate in histone pre-mRNA processing in vivo. Amino acids 105–154 of dFLASH bind to amino acids 1–78 of dLsm11. A two-amino acid mutation of dLsm11 that prevents dFLASH binding but does not affect localization of U7 snRNP to the HLB cannot rescue the lethality or histone pre-mRNA processing defects resulting from an Lsm11 null mutation. The last 45 amino acids of FLASH are required for efficient localization to the HLB in Drosophila cultured cells. Removing the first 64 amino acids of FLASH has no effect on processing in vivo. Removal of 13 additional amino acids of dFLASH results in a dominant negative protein that binds Lsm11 but inhibits processing of histone pre-mRNA in vivo. Inhibition requires the Lsm11 binding site, suggesting that the mutant dFLASH protein sequesters the U7 snRNP in an inactive complex and that residues between 64 and 77 of dFLASH interact with a factor required for processing. Together, these studies demonstrate that direct interaction between dFLASH and dLsm11 is essential for histone pre-mRNA processing in vivo and for proper development and viability in flies.

description: TOI-2076 b is a sub-Neptune-sized planet ($R= 2.39 \pm 0.10 {R_\oplus}$) that transits a young ($204 \pm 50 {MYr}$) bright ($V = 9.2$) K-dwarf hosting a system of three transiting planets. Using spectroscopic observations with the NEID spectrograph on the WIYN 3.5 m Telescope, we model the Rossiter-McLaughlin effect of TOI-2076 b, and derive a sky-projected obliquity of $λ=-3_{-15}^{+16\:\circ}$. Using the size of the star ($R=0.775 \pm0.015 {R_\odot}$), and the stellar rotation period ($P_{\mathrm{rot}}=7.27\pm0.23$ days), we estimate an obliquity of $ψ=18_{-9}^{+10\:\circ}$ ($ψ< 34^\circ$ at 95\% confidence), demonstrating that TOI-2076 b is on a well-aligned orbit. Simultaneous diffuser-assisted photometry from the 3.5 m Telescope at Apache Point Observatory rules out flares during the transit. TOI-2076 b joins a small but growing sample of young planets in compact multi-planet systems with well-aligned orbits, and is the fourth planet with an age $\lesssim 300$ Myr in a multi-transiting system with an obliquity measurement. The low obliquity of TOI-2076 b and the presence of transit timing variations in the system suggest the TOI-2076 system likely formed via convergent disk migration in an initially well-aligned disk.

We show that the fidelity of coherence does not in general satisfy the monotonicity requirement as a measure of coherence under the subselection of measurements condition. We find that the trace norm of coherence can act as a measure of coherence for qubit case and some special class of qutrits.

description: A novel strategy for extracting axial (AV) and toroidal (TV) vortices in the magnetically-induced current density (MICD) in molecular systems is introduced, and its pilot application to LiH molecule is demonstrated. It exploits differences in the topologies of AV and TV cores and involves two key steps: selecting a scalar function that can describe vortex cores in MICD and its subsequent topological analysis. The scalar function of choice is $Ω^{B_α}$ based on the velocity-gradient $Ω$ method known in research on classical flows. The Topological Data Analysis (TDA) is then used to analyze the $Ω^{B_α}$ scalar field. In particular, TDA robustly assigns distinct topological features of this field to different vortex types in LiH: AV to saddle-maximum separatrices which connect maxima to 2-saddles located on the domain's boundary, TV to a 1-cycle of the super-level sets of the input data. Both are extracted as the most \emph{persistent} features of the topologically-simplified $Ω^{B_α}$ scalar field.
The experimental OHC elongation phase is not inconsistent with effective transfer of mechanical power to the BM by the active force

description: The amazing development of the OCT techniques permits spatially well-defined measurement of the motion of a number of different solid structures within the Organ of Corti. Recent measurements [1] show the motion of the BM and of the RL in correspondence of each OHC row, as well as the motion of the junction between the OHC body and the Deiter’s cells. In the peak region, at low stimulus levels, the motion of the RL is larger than that of the BM. In a piezoelectric actuator model of the OHCs [2], the electric current is supposed to be proportional to the OHC elongation. Considering the low-pass phase rotation, the OHC force exerted on the BM may act as an anti-damping force, proportional to the RL velocity, and transfer power to both the RL and the BM. In this study, a WKB transmission-line cochlear model with two mechanical degrees of freedom at each tonotopic place is used, in which the OHC force is represented by a low-pass filtered elastic term proportional to the OHC elongation. With respect to our previous studies, this WKB model also includes the fluid focusing effect and the viscous damping effect in the peak region. In the model simulations, with a suitable parameter choice, the phase difference between the RL and the BM near the BF is consistent with some experimental findings, and the OHC power is effectively transmitted to the BM motion.

description: Although generally regarded as functional in the cytoplasm, a number of microRNAs (miRNAs) have been found in the nucleus, possibly with a role in gene regulation. Here we report that, in fact, a substantial fraction of all human miRNAs are present in the nucleus of neural stem cells. Further, subsets of these miRNAs display consistently higher standardized rank in the nucleus than in the cytoplasm of these cells, as identified with an RT-qPCR technology and confirmed by microarray analysis. Likewise, other miRNAs display higher cytoplasmic standardized ranks. Three samples were partitioned into nuclear and cytoplasmic fractions in six assays for 373 miRNAs. From the 100 most highly expressed miRNAs, standard scores of nuclear and cytoplasmic concentrations were determined. Among those, 21 miRNAs had all three nuclear standard scores higher than all three cytoplasmic scores; likewise, 31 miRNAs had consistently higher cytoplasmic scores. Random concentrations would result in only five in each set. Remarkably, if one miRNA has a high standard score in a compartment, then other miRNAs having the same 5′ seeds and certain similar 3′ end patterns are also highly scored in the same way. That is, in addition to the seed sequence, 3′ sequence similarity criteria identify families of mature miRNAs with consistently high nuclear or cytoplasmic expression.

description: We utilize IBM's quantum computers to perform a full quantum simulation of the optical quantum eraser (QE) utilizing a Mach-Zehnder interferometer with a variable partially-polarizing beam splitter (VPPBS) at the input. The use of the VPPBS motivates us to introduce the entangled quantum eraser, for which the path information is erased using a Bell-basis measurement. We also investigate the behavior of the wave aspect, i.e., the quantum coherence, as well as the particle character, represented by the predictability and entanglement, as delineated in complete complementarity relations (CCRs). As we show in this article, the utilization of the VPPBS uncover interesting aspects of the QE and CCRs. For instance, we can recover the full wave-behavior by the erasure procedure even when we have only partial knowledge about the path through entanglement.

description: We extend a recent approach to describe the $B^0$ and $B^0_s$ decays into $J/ψ$ $f_0(500)$ and $J/ψ$ $f_0(980)$, relating it to the $B^0$ and $B^0_s$ decays into $J/ψ$ and a vector meson, $ϕ$, $ρ$, $K^*$. In addition the $B^0$ and $B^0_s$ decays into $J/ψ$ and $κ(800)$ are evaluated and compared to the $K^*$ vector production. The rates obtained are in agreement with available experiment while predictions are made for the $J/ψ$ plus $κ(800)$ decay.

description: Cyber attacks have become commonplace and cause harm to IT systems operated by governments, businesses and citizens. As a result, there has been substantial job growth within the cyber security industry to try and meet the need for network defence. However, due to fierce competition for with the relevant skills there is a shortfall in skilled workers able to fill these roles. The goal of this project is to develop, validate and verify a novel solution for the recruitment of highly competent cyber security staff who can defend our nation against capable and well-funded adversaries. The proposed solution involves the development of a training scheme to train neurodiverse individuals for these roles. There is evidence for their interest and aptitude within the sector, but no research has been undertaken to establish how best to train them in the context of their individual differences.

description: During the peri- and early post-partum period, the gastrointestinal tract (GIT) of the calf is colonised by a combination of commensal and pathogenic microbes. Current understanding of the temporal microbial establishment of neonatal colon is, however, limited. This study focused on the ontogeny of colon microbiota establishment in Angus Beef calves from birth through weaning. Colon digesta contents were collected from Aberdeen Angus calves reared on two farms. Calves were euthanized at birth (n=7), day (D) 7 (n=7), D14 (n=6), D21 (n=7), D28 (n=6), and D96 (n=7) of life. Microbial DNA was extracted from colon samples and subjected to 16S rRNA amplicon sequencing. The effect of time on alpha (GLM procedure of SAS; 9.4) and beta (PERMANOVA) diversity of the colon microbiota was assessed with age and farm included as fixed effects. Differential abundance (Maaslin2) analyses were conducted with the same fixed effects. The alpha-diversity of the bacterial community progressed from birth onwards (D0 H’ mean = 0.59 and D96 H’ mean = 5.33) with apparent stabilisation between D14 v D21 (P=0.21). Weaning had a further statistically significant effect on the diversity of the colon microbiota (D28 v D96; P <0.001). Similarly, PERMANOVA analysis indicated stabilised colonisation of the colon microbiota from D14 to D21 (P=0.22), albeit weaning altered the colon microbiota (D28 v D96; P <0.001). This study is amongst the first to describe the ontogeny of colonisation of the colon microbiota, from birth to weaning in beef calves and provides fundamental information to support the establishment of beneficial microbes in the lower GIT of ruminants.

description: OHANA is an interferometric snapshot survey of the gaseous circumstellar environments of hot stars, carried out by the VLTI group at the Paranal observatory. It aims to characterize the mass-loss dynamics (winds/disks) at unexplored spatial scales for many stars. The survey employs the unique combination of AMBER's high spectral resolution with the unmatched spatial resolution provided by the VLTI. Because of the spatially unresolved central OBA-type star, with roughly neutral colour terms, their gaseous environments are among the easiest objects to be observed with AMBER, yet the extent and kinematics of the line emission regions are of high astrophysical interest.

description: This provocative article by Sango Mahanty and co-authors proposes rupture as a temporally and spatially expansive view of change and one that encompasses intersections with other crises. In our commentary, we put rupture to work as an analytic, thinking through the dynamics of China's massive Three Gorges Dam as a rupture episode with far-reaching disruption to everyday lives and hydrological and socio-economic systems. Through our consideration of the complex temporalities, spatial and material relationships, and generative sociopolitical potential of the Three Gorges Dam, we see value in the authors’ expansive view of change that looks well beyond the boundaries of ‘the project’. Practically speaking; however, we see the need to put some boundaries around our analysis, or the scope of rupture is potentially endless.

description: The Horizon Europe EM-TECH project brings together 10 participants from industry and academia to develop novel solutions to push the boundaries of electric machine technology for automotive traction. Target of this deliverable is to define the basic sizes (continuous and peak torque and power ratings, mass, expected available packaging envelopes) of the investigated components and systems for case studies. Furthermore, a set of integrated EM-TECH corner modules and on-board electric drive solutions for electric vehicles are defined to cover the widest possible range of vehicle segments. This deliverable also describes the associated machine control such as the cooling control and the inverter control for the new machines, and the vehicle controls to exploit the benefits to vehicle performance brought by the new machines, including the wheel slip control, the motor regenerative braking and braking blending, and the anti-jerk control.

description: The $n$-grid $E_n$ consists of $n$ equally spaced points in $[-1,1]$ including the endpoints $\pm 1$. The extremal polynomial $p_n^*$ is the polynomial that maximizes the uniform norm $\| p \|_{[-1,1]}$ among polynomials $p$ of degree $\leq αn$ that are bounded by one on $E_n$. For every $α\in (0,1)$, we determine the limit of $\frac{1}{n} \log \| p_n^*\|_{[-1,1]}$ as $n \to \infty$. The interest in this limit comes from a connection with an impossibility theorem on stable approximation on the $n$-grid.

description: Nella causa C-248/16, Slowakische Republik (Repubblica slovacca) contro Achmea Bv, la Corte di Giustizia dell?Unione Europea ha statuito che le clausole arbitrali presenti nei Trattati Bilaterali di Investimento tra gli Stati Membri dell?Unione Europea sono precluse dal diritto dell?Unione. Tuttavia, negli ultimi due anni, i tribunali arbitrali investiti delle controversie in materia di investimento all?interno dell?UE hanno continuato ad affermare la propria giurisdizione. Nel presente elaborato, l?impatto della sentenza Achmea sull?arbitrato degli investimenti � analizzato nel contesto del dibattito sui processi di costituzionalizzazione al di fuori dello Stato, con riguardo, altres�, al ruolo della proliferazione delle giurisdizioni internazionali. A tal fine, la tesi si sofferma sulla cruciale importanza degli organi giudicanti nell?ordinamento internazionale e sul loro peso nel dibattito accademico. In particolare, il primo capitolo fornisce una preliminare panoramica della dottrina del Costituzionalismo Globale, introducendone i fondamenti concettuali rilevanti, ed analizza specificamente alcune ricostruzioni accademiche in questo ambito. Il secondo capitolo, invece, illustra le caratteristiche fondamentali della funzione giudiziaria internazionale, affrontando il rapporto tra il rapido aumento dei meccanismi di risoluzione delle controversie e la frammentazione dell?ordinamento giuridico internazionale. Il capitolo conclusivo � incentrato sull?arbitrato degli investimenti, con riguardo alle critiche mosse al sistema ISDS e alle ragioni per cui quest?ultimo pu� essere considerato un esempio paradigmatico di frammentazione. In particolare, sono prese in esame le questioni emerse nel contesto dell?arbitrato degli investimenti in ambito europeo e sono evidenziati i principali argomenti sollevati in merito all?incompatibilit� di quest?ultimo con il diritto dell?Unione. Sono inoltre trattate le conclusioni della Corte di Giustizia nel caso Achmea, tenuto conto della prospettiva costituzionale di cui al primo capitolo. Infine, la parte conclusiva intende illustrare le reazioni delle principali parti interessate alla decisione. Segnatamente, l?ultima sezione del terzo capitolo d� conto degli argomenti addotti dai tribunali arbitrali allo scopo di restringere la portata della decisione della Corte. Sono inoltre tenuti in considerazione l?approccio dei tribunali nazionali, ancora in corso di evoluzione, nonch� le recenti azioni intraprese dalla Commissione europea e dagli Stati Membri, con particolare riferimento all?Accordo per la risoluzione dei Trattati Bilaterali di Investimento tra Stati Membri del 5 Maggio 2020.
