description: We study the neutron electric dipole moment in the presence of the CP-violating operators up to the dimension five in terms of the QCD sum rules. It is found that the OPE calculation is robust when exploiting a particular interpolating field for neutron, while there exist some uncertainties on the phenomenological side. By using input parameters obtained from the lattice calculation, we derive a conservative limit for the contributions of the CP violating operators. We also show the detail of the derivation of the sum rules.

Pseudopowers and primality proving

description: It has been known since the 1930s that so-called pseudosquares yield a very powerful machinery for the primality testing of large integers N. In fact, assuming reasonable heuristics (which have been confirmed for numbers to 2^80) this gives a deterministic primality test  in time O((lg N)^(3+o(1))), which many believe to be best possible. In the 1980s D.H. Lehmer posed a

question tantamount to whether this could be extended to pseudo r-th powers. Very recently, this was accomplished for r=3. In fact, the results obtained indicate that r=3 might lead to an even more powerful algorithm than r=2. This naturally leads to the challenge if and how anything can be achieved for r>3. The extension from r = 2 to r = 3 relied on properties of the arithmetic of the Eisenstein ring of integers Z[\zeta_3], including the Law of Cubic Reciprocity. In this paper we present a generalization of our result for any odd

prime r. The generalization is obtained by studying the properties of Gaussian and Jacobi sums in cyclotomic ring of integers, which are tools from which the r-th power Eisenstein Reciprocity Law is derived, rather than from the law itself. While r=3 seems to lead to a more efficient algorithm than r=2, we show that extending to any r>3 does not appear to lead to any further improvements.

description: As a test of the new light-front coupled-cluster method in a gauge theory, we apply it to the nonperturbative construction of the dressed-electron state in QED, for an arbitrary covariant gauge, and compute the electron's anomalous magnetic moment. The construction illustrates the spectator and Fock-sector independence of vertex and self-energy contributions and indicates resolution of the difficulties with uncanceled divergences that plague methods based on Fock-space truncation.

Tardigrade: An Atomic Broadcast Protocol for Arbitrary Network Conditions
Creators: name: Blum, Erica
name: Katz, Jonathan

Publisher: name: CISPA
Year: 2023

description: We study the problem of \emph{atomic broadcast}---the underlying problem addressed by blockchain protocols---in the presence of a malicious adversary who corrupts some fraction of the $n$ parties running the protocol. Existing protocols are either robust for any number of corruptions in a \emph{synchronous} network (where messages are delivered within some known time~$\Delta$) but fail if the synchrony assumption is violated, or tolerate fewer than $n/3$ corrupted parties in an \emph{asynchronous} network (where messages can be delayed arbitrarily) and cannot tolerate more corruptions even if the network happens to be well behaved. %Although protocols for the latter case give seemingly stronger guarantees, this is not the case since they (inherently) tolerate a lower fraction of corrupted parties. \smallskip We design an atomic broadcast protocol (\name) that, for any $t_s \geq t_a$ with $2t_s + t_a < n$, provides security against $t_s$ corrupted parties if the network is synchronous, while remaining secure when $t_a$ parties are corrupted even in an asynchronous network. We show that \name~achieves optimal tradeoffs between $t_s$ and~$t_a$. Finally, we show a second protocol (\nametwo) with similar (but slightly weaker) guarantees that achieves per-transaction communication complexity linear in~$n$.

description: The present work was designed to gain an insight into the enzymatic catalysis performed by a specific group of enzymes, Zn-metalloenzymes. A detailed review of the literature yielded five enzymes participating in the hydrolytic bond breaking reactions which were of interest for the theoretical study of Zn metalloenzymes. For these enzymes the common reaction step, activation of water by deprotonation of a Zn-bound water ligand, was identified from literature review. The water activation was studied in detail for the five different enzymes and it was found that the process is facilitated by a combined effect of water polarization by Zn, and the stabilizing effect that the Zn coordination center has on the resulting hydroxide. The present work also explored in detail the reaction mechanism of one particular enzyme, adenosine deaminase. A novel and complete description of the reaction mechanism for this enzyme was achieved, providing with important new insights into the details of hydrolytic reactions which would not be available from experimental work.

description: The most commonly used parameterizations of the Yukawa couplings in the two Higgs doublet model are revisited. Their similitudes and differences are emphasized and relations between the different notations used in the literature are derived. Using these relations, bounds on the space of parameters of the charged Higgs sector of the two Higgs doublet model are obtained. These constraints are obtained from flavor observables like the measurement of B -> Xs γand the recent measurement of Bs -> μ+ μ- from LHCb. The ratio R_{H+}=B(H+ -> τ^+ ν_τ)/B(H+ -> t b) is evaluated for the two Higgs doublet model type-III and type-II, and their differences are quantified.

Quantifying the effect of rock mass quality on peak particle velocity for underground drift development
Creators: name: Caceres, Cristian Andres Caceres
Publisher: name: University of British Columbia
Year: 2012

description: In prior research the existence of the strong relation between peak particle velocity (PPV), as a result of blasting, and damage to civil structures and mining excavations has been well established. In essence, the higher the PPV levels, the greater has been the observed damage to a structure or excavation. The first part of this thesis examines, through case studies in four underground mines, the relationship observed between measured PPV and induced overbreak. These developed relationships were established through a blast monitoring campaign of drift development headings of markedly dissimilar rock mass qualities, varying from fair/poor to extremely competent. In the second part of this thesis is developed of a new methodology to estimate PPV, which incorporates input parameters that are characteristic of different rock mass qualities, such as propagation velocity and resonance frequency, and explosive characteristics such as velocity of detonation (VOD). This methodology makes use of waveforms to determine vibration levels from which the PPV of a blasthole is established. The developed model estimates PPV by taking into consideration the spatial location of the blasthole with respect to both the drift face, and the point of interest, and the arrival time difference of every incremental charge (or packet) within a blasthole based on the travel distance of the seismic wave, the VOD, and the rock mass propagation velocities. Current state of the art methodologies are solutions to a particular blasting situation; they either consider a specific close range geometry, where they have limited applicability, or they tend to be over simplified in the far-field by considering the explosive charge as a point source. The proposed methodology considers a more realistic close range geometric solution that can be applied specifically to a drifting situation, and improves some of the drawbacks of current methodologies in the far-field range. Finally, a more reliable estimation of PPV levels can help in the assessment of the damage potential of a particular structure or excavation and therefore should help toward preventive measures to make the working environment more safe and cost effective.

Revisiting the Security of COMET Authenticated Encryption Scheme

Publisher: name: CISPA
Year: 2023

description: COMETv1, by Gueron, Jha and Nandi, is a mode of operation for nonce-based authenticated encryption with associated data functionality. It was one of the second round candidates in the ongoing NIST Lightweight Cryptography Standardization Process. In this paper, we study a generalized version of COMETv1, that we call gCOMET, from provable security perspective. First, we present a comprehensive and complete security proof for gCOMET in the ideal cipher model. Second, we view COMET, the underlying mode of operation in COMETv1, as an instantiation of gCOMET, and derive its concrete security bounds. Finally, we propose another instantiation of gCOMET, dubbed COMETv2, and show that this version achieves better security guarantees as well as memory-efficient implementations as compared to COMETv1.
On the oriented chromatic number of dense

graphs
Creators: name: Wood, David R.
Publisher: name: Faculty of Science, University of Calgary
Year: 2007

description: Let $G$ be a graph with $n$ vertices, $m$ edges, average degree $\delta$, and maximum degree $\Delta$. The \emph{oriented chromatic number} of $G$ is the maximum, taken over all orientations of $G$, of the minimum number of colours in a proper vertex colouring such that between every pair of colour classes all edges have the same orientation. We investigate the oriented chromatic number of graphs, such as the hypercube, for which $\delta\geq\log n$. We prove that every such graph has oriented chromatic number at least $\Omega(\sqrt{n})$. In the case that $\delta\geq(2+\epsilon)\log n$, this lower bound is improved to $\Omega(\sqrt{m})$. Through a simple connection with harmonious colourings, we prove a general upper bound of $\Oh{\Delta\sqrt{n}}$ on the oriented chromatic number. Moreover this bound is best possible for certain graphs. These lower and upper bounds are particularly close when $G$ is ($c\log n$)-regular for some constant $c>2$, in which case the oriented chromatic number is between $\Omega(\sqrt{n\log n})$ and $\mathcal{O}(\sqrt{n}\log n)$.

Spring geochemistry: a tool for mineral exploration in the South Nahanni River Basin, NWT

description: Geochemical data from over 200 springs within the remote 37,000 kms South Nahanni River Basin of the Mackenzie Mountains, Northwest Territories, were used to evaluate the economic mineral potential of the region which is proposed for a national park designation. Trace element analyses were evaluated using three different approaches (the sum of trace element concentrations as a percentage of total dissolved solids, identifying individual elevated trace elements, and the inverse use of the Ficklin Diagram). Two out of the three approaches detected the two known deposits of the area, Prairie Creek and Tungsten, but not with the same method in each case, indicating that a multi-pronged approach is best. The springs are elevated in trace elements in comparison to mineral deposit related waters around the world. Silica geothermometry determined the average depth of circulation of the springs to be 2.1 km in the warm or hot springs and ranging from 4. 7 km to less than 200 m for the entire dataset, indicative of the accessibility of the predicted mineralized zones. These simple statistical and graphing methods can identify mineralized zones quickly and efficiently in a largely under-explored area.
Affinely regular polygons in an affine plane

Year: 2008

description: In this paper we survey results about affinely regular polygons. First, the definitions and classification of affinely regular polygons are given. Then the theory of Bachmann-Schmidt is outlined. There are several classical theorems about regular polygons, some of them having analogues in finite planes, such as the Napoleon-Barlotti theorem. Such analogues, variants of classical theorems are also collected. Affinely regular polygons occur in many combinatorial problems for sets in a finite plane. Some of these results about sharply focused arcs, internal and external nuclei, complete arcs are collected. Finally, bounds on the number of chords of an affinely regular polygon through a point are discussed.

Seiberg duality for Chern-Simons quivers and D-brane mutations

description: Chern-Simons quivers for M2-branes at Calabi-Yau singularities are best understood as the low energy theory of D2-branes on a dual type IIA background. We show how the D2-brane point of view naturally leads to three dimensional Seiberg dualities for Chern-Simons quivers with chiral matter content: They arise from a change of brane basis (or mutation), in complete analogy with the better known Seiberg dualities for D3-brane quivers. This perspective reproduces the known rules for Seiberg dualities in Chern-Simons-Yang-Mills theories with unitary gauge groups. We provide explicit examples of dual theories for the quiver dual to the Y^{p,q}(CP^2) geometries. We also comment on the string theory derivation of CS quivers dual to massive type IIA geometries.

description: We present the discovery and follow-up observations of SN 2008jb, a core-collapse supernova in the dwarf irregular galaxy ESO 302-14 at 9.6 Mpc. This transient was missed by galaxy-targeted surveys and was only found in archival optical images obtained by CRTS and ASAS. It was detected shortly after explosion and reached a bright optical maximum, Vmax = 13.6 mag (M_Vmax ~ -16.5). The shape of the light curve shows a plateau of 100 days, followed by a drop of 1.4 mag in V-band to a decline with the approximate Co 56 decay slope, consistent with 0.04 Msun of Ni 56 synthesized in the explosion. A spectrum obtained 2 years after explosion shows a broad, boxy Halpha emission line, which is unusual for type IIP supernovae. We detect the supernova in archival Spitzer and WISE images obtained 8-14 months after explosion, which show clear signs of warm dust emission. The dwarf irregular host galaxy has a low gas-phase oxygen abundance, 12 + log(O/H) = 8.2 (~1/5 Solar), similar to those of the SMC and the hosts of long gamma-ray bursts and luminous core-collapse supernovae. We study the host environment using GALEX FUV, R-band, and Halpha images and find that the supernova occurred in a large star-formation complex. The morphology of the Halpha emission appears as a large shell (R = 350 pc) surrounding the FUV and optical emission. We estimate an age of ~9 Myr and a total mass of ~2 x 10^5 Msun for the star-formation complex. These properties are consistent with the expanding Halpha supershells observed in well-studied nearby dwarf galaxies, which are tell-tale signs of feedback from the cumulative effect of massive star winds and supernovae. The age estimated for the star-forming region suggests a relatively high-mass progenitor star with initial mass of ~20 Msun. We discuss the implications of these findings in the study of core-collapse supernova progenitors. (Abridged)

description: This paper proposes a lightweight short-tweak tweakable blockcipher (tBC) based authenticated encryption (AE) scheme tHyENA, a tweakable variant of the high profile NIST LWC competition submission HyENA. tHyENA is structurally similar to HyENA, however, proper usage of short-tweaks for the purpose of domain separation, makes the design much simpler compact. We know that HyENA already achieves a very small hardware footprint, and tHyENA further optimizes it. To realize our claim, we provide NIST API compliant hardware implementation details and benchmark for tHyENA against HyENA and several other well-known sequential feedback-based designs. The implementation results depict that when instantiated with the tBC TweGIFT, tHyENA achieves an extremely low hardware footprint - consuming only around 680 LUTs and 260 slices while maintaining the full rate and the almost birthday bound security. To the best of our knowledge, this figure is significantly better than all the known implementation results of other lightweight ciphers with sequential structures.

description: Tweakable block cipher (TBC), a stronger notion than standard block ciphers, has wide-scale applications in symmetric-key schemes. At a high level, it provides flexibility in design and (possibly) better security bounds. In multi-keyed applications, a TBC with short tweak values can be used to replace multiple keys. However, the existing TBC construction frameworks, including TWEAKEY and XEX, are designed for general purpose tweak sizes. Specifically, they are not optimized for short tweaks, which might render them inefficient for certain resource constrained applications. So a dedicated paradigm to construct short-tweak TBCs (tBC) is highly desirable. In this paper, as a first contribution, we present a dedicated framework, called the Elastic-Tweak framework (ET in short), to convert any reasonably secure SPN block cipher into a secure tBC. We apply the ET framework on GIFT and AES to construct efficient tBCs, named TweGIFT and TweAES. These short-tweak TBCs have already been employed in recent NIST lightweight competition candidates, LOTUS-LOCUS and ESTATE. As our second contribution, we show some concrete applications of ET-based tBCs, which are better than their block cipher counterparts in terms of key size, state size, number of block cipher calls, and short message processing. Some notable applications include, Twe-FCBC (reduces the key size of FCBC and gives better security than CMAC), Twe-LightMAC Plus (better rate than LightMAC Plus), Twe-CLOC, and Twe-SILC (reduces the number of block cipher calls and simplifies the design of CLOC and SILC).
The impacts of wildfire and Mountain Pine Beetle disturbance on wood budgets, stability and related sediment storage in low-sediment supply streams of the Okanagan Basin
Creators: name: King, Leonora Adele
Publisher: name: University of British Columbia
Year: 2012

description: This thesis presents the Large Woody Debris (LWD) budgets and related sediment dynamics of 12 headwater streams in the Okanagan Basin of British Columbia. The study streams include 3 wildfire (from the recent Okanagan Mountain Park Fire in 2003) sites and 3 control sites in the Interior Douglas-fir (IDF) biogeoclimatic zone, and 3 recent Mountain Pine Beetle (MPB) infestation sites and 3 control sites in the Montane Spruce (MS) zone. The wood budget components were quantified based on repeated annual wood surveys, and represent the first wood budgets produced in the literature. Wildfire was found to significantly increase annual wood recruitment by more than an order of magnitude over undisturbed or control streams. MPB had not significantly increased LWD recruitment, but is expected to increase over the coming decades. Both of the riparian disturbances had shifted the size distribution of recruits to larger wood sizes. Our analysis confirms that the matrix of relative wood size presented by Hassan et al. (2005) is a good predictor of wood stability and export. Wood stability was in turn a primary determinant of wood function and the role of wood in sediment storage. Wood in the study streams stored between 0% and 90% of the sediment in the channels. Sediment stores increased with increasing functional wood loading. This highlights an important role of LWD in sediment storage in spite of large variations. However, in contrast to literature on the role of LWD in supply-rich streams, LWD in our supply-limited streams was found to have no statistical relationship to sediment diversity and was found to be less effective at causing sediment fining. We suggest that LWD-related sediment storage sites in supply-limited streams replace rather than supplement alluvial storage sites as they would in sediment-supply rich streams, and thus do not increase sediment diversity. Furthermore, LWD is a less important roughness element in these step-pool systems compared to pool-riffle systems, and is thus not effective at causing sediment fining under step-pool conditions.

description: The problem of constructing a perfect cuboid is related to a certain class of univariate polynomials with three integer parameters $a$, $b$, and $u$. Their irreducibility over the ring of integers under certain restrictions for $a$, $b$, and $u$ would mean the non-existence of perfect cuboids. This irreducibility is conjectured and then verified numerically for approximately 10000 instances of $a$, $b$, and $u$.

description: Over the past few decades, gender studies have reinvigorated the way in which we talk about romanticism. The article discusses some of the key developments and their critical consequences. Critical interventions have not only redirected our reading of familiar texts, but also fundamentally destabilized the canon and even made us question the validity of the label ‘romanticism’ itself. Recent critical work is beginning to uncover a mobile syntax of gender roles. The article focuses on how criticism is beginning to discern an unstable distribution of gender characteristics across the spectrum of literary writing.

Of Male Bondage

description: Classical Hollywood melodrama, often referred to as “women’s films,” are defined through their heightened emotional intensity and their confrontation of social issues. While usually regarded as finished by the late 1950s, in the past decade melodrama has returned in the different form of the male melodrama, articulating a concern with and anxiety of male frailty. In Nicolas Winding Refn’s delirious male melodrama Only God Forgives (2013), violence takes the place of crying as the expression of emotional intensity. The movie’s primary deviance from classical melodrama comes through in its emphasis on the body in pain as the locus for contemporary male gender trouble. This paper will investigate the gender negotiations of the movie through its reactualization of melodrama as a male gender form.

description: Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease in children. Nonsteroidal anti-inflammatory drugs (NSAIDs) and intra-articular corticosteroid injections are first-line therapy for oligoarticular JIA. NSAIDs Adverse events (AEs) include gastrointestinal ulcers/bleeding and impaired renal function. The most prescribed NSAIDs for oligoarticular JIA are ibuprofen and naproxen. However, direct comparison between these drugs is lacking. We aimed to compare the efficacy and safety of ibuprofen versus naproxen for oligoarticular JIA. This is a bi-national retrospective study of oligoarticular JIA patients treated with either ibuprofen or naproxen as first-line therapy. Efficacy was defined as patients that achieved complete response (no evidence for arthritis). Safety was assessed by the occurrence of adverse events during follow-up. Of 164 patients, 103 were treated in the Israeli group and 61 in the US group. The study population had a mean age of 4.49 ± 3.55 years, with F:M ratio of ∼2.5:1. No significant difference was found in drug efficacy [Complete response was observed in 15% of the ibuprofen group vs. 17.3% in naproxen group (p = 0.7)]. Treatment duration > 28 days was associated with significantly higher odds for complete response (p = 0.021). For safety, 12 AEs were associated with naproxen, whereas no AEs were associated with ibuprofen (p = 0.004). Treatment was discontinued in all AEs cases. Ibuprofen and naproxen showed similar albeit low efficacy which emphasizes their role as bridging therapy until IACI is achieved. However, ibuprofen showed better safety profile naproxen and therefore should be considered as first-line therapy. Ibuprofen and Naproxen showed similar albeit low efficacy which emphasizes their role as bridging therapy until IACI is achieved.Ibuprofen showed better safety profile than naproxen and therefore should be considered as first-line therapy.

description: The article focuses on an example of chick lit jr., Meg Cabot’s Airhead-trilogy, and how feminism, postfeminism and girlpower are discussed in this text. The novels portray a conflict between the generations, where the daughter rejects her mother’s version of feminism. There is an interesting ambiguity in the text concerning feminist ideals which makes Cabot’s novels, along with many other examples of chick lit jr., difficult to define. But even if there’s a remnant of feminism in these novels, that version of feminism stays on the individual plane and never influences society as a whole.

description: In this work we study creep flow behavior of suspension of Polyaniline (PANI) particles in silicone oil under application of electric field. Suspension of PANI in silicone oil, a model electrorheological fluid, shows enhancement in elastic modulus and yield stress with increase in the magnitude of electric field. Under creep flow field, application of greater magnitude of electric field reduces strain induced in the material while application of greater magnitude of shear stress at any electric field enhances strain induced in the material. Remarkably, time evolution of strain in PANI suspension at different stresses, electric field strengths and concentrations show superposition after appropriate shifting of the creep curves on time and strain axes. Observed electric field - shear stress - creep time - concentration superposition demonstrates self-similarity in electrorheological behavior. We analyze the experimental data using Bingham and Klingenberg - Zukoski model and observe that the latter predicts the experimental behavior very well. We conclude by discussing remarkable similarities between observed rheological behavior of ER fluids and rheological behavior of aging soft glassy materials.

description: This paper proposes a lightweight authenticated encryption (AE) scheme, called Light-OCB, which can be viewed as a lighter variant of the CAESAR winner OCB as well as a faster variant of the high profile NIST LWC competition submission LOCUS-AEAD. Light-OCB is structurally similar to LOCUS-AEAD and uses a nonce-based derived key that provides optimal security, and short-tweak tweakable blockcipher (tBC) for efficient domain separation. Light-OCB improves over LOCUS-AEAD by reducing the number of primitive calls, and thereby significantly optimizing the throughput. To establish our claim, we provide FPGA hardware implementation details and benchmark for Light-OCB against LOCUS-AEAD and several other well-known AEs. The implementation results depict that, when instantiated with the tBC TweGIFT64, Light-OCB achieves an extremely low hardware footprint - consuming only around 1128 LUTs and 307 slices (significantly lower than that for LOCUS-AEAD) while maintaining a throughput of 880 Mbps, which is almost twice that of LOCUS-AEAD. To the best of our knowledge, this figure is significantly better than all the known implementation results of other lightweight ciphers with parallel structures.

description: We present a detailed investigation of the near-to-far infrared (IR) spectral energy distribution (SED) of a large sample of Spitzer-observed active galactic nuclei (AGN). We fitted the spectra of 51 narrow line Seyfert 1 galaxies (NLS1s) and 64 broad line Seyfert 1 galaxies (BLS1s) using a three component model: a clumpy torus, a dusty narrow line region (NLR) and hot pure-graphite dust located in the outer part of the broad line region (BLR). The fitting is performed on star formation (SF) subtracted SEDs using SF templates that take into account the entire range of possible host galaxy properties. We find that the mid-IR intrinsic emission of NLS1s and BLS1s are very similar, regardless of the AGN luminosity, with long wavelength downturn at around 20-25 um. We present a detailed model of the hot dust component that takes into account the distribution of dust temperature within the clouds and their emission line spectrum. The hot dust continuum provides a very good fit to the observed near-IR continuum spectrum. Most line emission in this component is dramatically suppressed, except MgII(2798A) and HeI lines that are still contributing significantly to the total BLR spectrum. We calculate the covering factors of all the AGN components and show that the covering factor of the hot-dust clouds is about 0.15-0.35, similar to the covering factor of the torus, and is anti-correlated with the source luminosity and the normalized accretion rate.

Controlled generation of momentum states in a high-finesse ring cavity

Subjects: subject: Quantum Gases (cond-mat.quant-gas)

description: A Bose-Einstein condensate in a high-finesse ring cavity scatters the photons of a pump beam into counterpropagating cavity modes, populating a bi-dimensional momentum lattice. A high-finesse ring cavity with a sub-recoil linewidth allows to control the quantized atomic motion, selecting particular discrete momentum states and generating atom-photon entanglement. The semiclassical and quantum model for the 2D collective atomic recoil lasing (CARL) are derived and the superradiant and good-cavity regimes discussed. For pump incidence perpendicular to the cavity axis, the momentum lattice is symmetrically populated. Conversely, for oblique pump incidence the motion along the two recoil directions is unbalanced and different momentum states can be populated on demand by tuning the pump frequency.

A Weaker Faithfulness Assumption based on Triple Interactions
Creators: name: Marx, Alexander

description: One of the core assumptions in causal discovery is the faithfulness assumption—i.e. assuming that independencies found in the data are due to separations in the true causal graph. This assumption can, however, be violated in many ways, including xor connections, deterministic functions or cancelling paths. In this work, we propose a weaker assumption that we call 2-adjacency faithfulness. In contrast to adjacency faithfulness, which assumes that there is no conditional independence between each pair of variables that are connected in the causal graph, we only require no conditional independence between a node and a subset of its Markov blanket that can contain up to two nodes. Equivalently, we adapt orientation faithfulness to this setting. We further propose a sound orientation rule for causal discovery that applies under weaker assumptions. As a proof of concept, we derive a modified Grow and Shrink algorithm that recovers the Markov blanket of a target node and prove its correctness under strictly weaker assumptions than the standard faithfulness assumption.

description: The incidence of hepatic immune-related adverse events has increased with the wide use of immune checkpoint inhibitors (ICIs), some immune-mediated hepatotoxicity (IMH) cases are severe and lack of clinical recommendations. This study aimed to evaluate the efficacy of artificial liver support systems (ALSSs) in the treatment of IMH. This retrospective case series included six patients with grade 4 hepatotoxicity with high bilirubin induced by ICIs treated between 1 January 2019 and 31 December 2021. All patients received ALSS treatment. After treatment and recovery, four of the six patients experienced improvement in hepatotoxicity, with total bilirubin (TBIL) levels reduced to ≤ grade 2, and two patients achieved complete recovery (TBIL grade = 0). ALSS serve as a therapeutic option for severe IMH.
The Concept of the Gentleman

description: The ideal of the gentleman has been globally reborn in PSY’s colossal YouTube hit “Gentleman M V”. This video thematizes the concept of the gentleman, but it is also a reformulation of gentlemanly behaviour. The article analyses the ideal of the gentleman in the light of its gender aspects and its class connotations. The hypothesis of the article is that the insecure status of masculine identity in an age of post-second-generation feminism demands the seemingly parodic treatment of the concept of the gentleman, as in this video. Yet this hypothesis is also a research question. Why is there this strong element of parody in the video? The answer to the question may depend on a consideration of contemporary male identities. It may also be based on a reading of how the music video incorporates these types. Three such types are described in the article: the new man, the metrosexual male and the new lad. It is the conclusion of the article that “Gentleman M V” incorporates the last two of these.

Variety of SO(10) GUTs with Natural Doublet-Triplet Splitting via the Missing Partner Mechanism

description: We present a new class of unified SO(10) models where the GUT symmetry breaking down to the standard model gauge group involves just one scale, in contrast to the conventional SO(10) models which require two scales. Further, the models we discuss possess a natural doublet-triplet splitting via the missing partner mechanism without fine tuning. Such models involve $560+\ov{560}$ pair of heavy Higgs fields along with a set of light fields. The $560+\ov{560}$ are the simplest representations of SO(10) besides the $126+\ov{126}$ which contain an excess of color triplets over $SU(2)_L$ doublets. We discuss several possibilities for realizing the missing partner mechanism within these schemes. With the $126+\ov{126}$ multiplets, three viable models are found with additional fields belonging to ${210 + 2 \times 10 + 120}$, ${45 + 10 + 120}$, or ${210 + 16 + \ov{16} + 10 + 120}$. With the $560+\ov{560}$, a unique possibility arises for the missing partner mechanism, with additional ${2\times 10+ 320}$ fields. These models are developed in some detail. It is shown that fully realistic fermion masses can arise in some cases, while others can be made realistic by addition of vector--like representations. Naturally large neutrino mixing angles, including sizable $θ_{13}$, can emerge in these models. The couplings of the $H_u(H_d)$ Higgs doublets of the MSSM which give masses to the up quarks (down quarks and leptons) are not necessarily equal at the grand unification scale and would lead to a new phenomenology at the low energy scales.

description: A measurement of jet activity in the rapidity interval bounded by a dijet system is performed using pp collisions at 7 TeV recorded by the ATLAS detector in 2010. The data are compared to LO predictions from PYTHIA, HERWIG++ and ALPGEN event generators. The data are also compared to NLO parton shower prediction from POWHEG, when interfaced to PYTHIA or HERWIG parton shower, and all order resummation prediction from HEJ. In most of the phase-space regions presented, the experimental uncertainty is much smaller than the spread of LO Monte Carlo event generator predictions. In general, POWHEG+PYTHIA gave the best description of the data.

Estimating Conditional Mutual Information for Discrete-Continuous Mixtures using Multi-Dimensional Adaptive Histograms

Publisher: name: CISPA

description: Estimating conditional mutual information (CMI) is an essential yet challenging step in many machine learning and data mining tasks. Estimating CMI from data that contains both discrete and continuous variables, or even discrete-continuous mixture variables, is a particularly hard problem. In this paper, we show that CMI for such mixture variables, defined based on the Radon-Nikodym derivate, can be written as a sum of entropies, just like CMI for purely discrete or continuous data. Further, we show that CMI can be consistently estimated for discrete-continuous mixture variables by learning an adaptive histogram model. In practice, we estimate such a model by iteratively discretizing the continuous data points in the mixture variables. To evaluate the performance of our estimator, we benchmark it against state-of-the-art CMI estimators as well as evaluate it in a causal discovery setting.
