This small, brown snake has a white, black-bordered line that goes from the postoculars through the fifth and sixth dorsal rows to the tip of the tail. The vertebral region is a little paler than below the lines. Specimens of Rhadinaea decorata often have a subpreocular scale and 110–134 ventral scales (Myers 1974). The most similar species in the region is Urotheca fulviceps, which has a reddish or purple head band, a pale line running along the first and second dorsal scale rows and more than 136 ventrals.

Subjects: subject: High Energy Physics - Theory (hep-th)

description: Following on from previous work we derive the non-linear differential equations of more general correlators of U(1) twist fields in two-dimensional massive Dirac theory. Using the conserved charges of the double copy model equations parametrising the correlators of twist fields with arbitrary twist parameter are found. This method also gives a parametrisation of the correlation functions of general, fermionic, descendent twist fields. The equations parametrising correlators of primary twist fields are compared to those of the literature and evidence is presented to confirm that these equations represent the correct parametrisation.

description: Acute promyelocytic leukemia (APL) is characterized by the translocation t(15;17)(q22;q21), resulting in the promyelocytic leukemia (PML)-retinoic acid receptor alpha (RARA) fusion protein in 95% cases whereas variant translocations involving PLZF (11q23), NPM (5q35), NUMA (11q13) and STAT5b (17q23) account for the rest. Leukemias with PML-RARA translocations respond well to all-trans retinoic acid (ATRA) or arsenic trioxide (ATO) therapy whereas those with PLZF-RARA fusions respond poorly. Although primary resistance to ATRA is rare, secondary or acquired resistance is frequently observed in patients treated with ATRA alone or in combination with other chemotherapy regimens. However, molecular abnormalities mediating resistance to ATRA therapy are underexplored. Here, we report two cases of APL with RARA-PML deletions on der(17) or der(15), which displayed clinical evidence of primary and secondary resistance to therapy, respectively.

Key Ideas and Concepts of Institutional Economic Theory
Creators: name: Nesheva-Kiosseva, Ninel Ivanova
Publisher: name: International Journal of Business Innovation
Year: 2023

description: A large number of scientific publications argue that environmental, social, sustainability, integrated, CSR reporting and ESG, or all we call "non-financial reporting", have a theoretical basis in institutional economic theory. However, there is no clear identification of the specific achievements of the institutional theory, which served as the basis for the transformation of accountability from "technological financial" to non-financial. Our knowledge of how accounting and reporting forms arise is relatively weak compared to our knowledge of accounting procedures and techniques. We usually think that accounting and accounting have nothing to do with economic theory, societies, and the complex process of transferring ideas over time from one science to another. This paper aims to present the main key ideas, the “red markers” in institutional theory that form the theoretical basis of the applied tools of non-financial accounting. The scientific task of this study is to discover, select, highlight and systematize in problem-chronological terms the main and most important theoretical components of the conceptual and methodological change in institutional economic theory that have contributed to the creation of the tools called general "non-financial accounting and reporting". The relevance of such a study is determined by the need to identify, systematize and analyse the theoretical roots of non-financial accountability, which is an important methodological issue for the present and future development of non-financial accounting and reporting. Overall, the study tries to throw the bridge between economic theory and the new directions of non-financial reporting.

Prospects for improved $Λ_c$ branching fractions
Creators: name: Rosner, Jonathan L.
Publisher: name: arXiv
Year: 2012
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The experimental uncertainty on the branching fraction $\b(Λ_c \to p K^- π^+) = (5.0 \pm 1.3)%$ has not decreased since 1998, despite a much larger data sample. Uncertainty in this quantity dominates that in many other quantities, including branching fractions of $Λ_c$ to other modes, branching fractions of $b$-flavored baryons, and fragmentation fractions of charmed and bottom quarks. Here we advocate a lattice QCD calculation of the form factors in $Λ_c \to Λ\ell^+ ν_\ell$ (the case $\ell = e^+$ is simpler as the mass of the lepton can be neglected). Such a calculation would yield an absolute prediction for the rate for $Λ_c \to Λ\ell^+ ν_\ell$. When combined with the $Λ_c$ lifetime, it could provide a calibration for an improved set of $Λ_c$ branching fractions as long as the accuracy exceeds about 25%.

description: This study analyses the effect of the Board of Directors’ characteristics on the disclosure of non-financial information by Portuguese listed companies, in the context of the Directive 2014/95/EU. To this end, a non-financial information disclosure index was built, based on the Directive disclosure requirements and a set of items defined in the GRI standards. The results obtained show that the diversity of nationalities in the Board has a positive effect on the non-financial information disclosed regarding all topics provided for in the Directive, except for information on the business model. The academic background of the Board, i.e., the presence of members with master’s or doctoral degrees has a positive effect on the disclosure of information on social matters. Board size, Board independence, CEO duality, Board gender diversity and Board activity do not appear to influence non-financial information disclosures. The findings support the need to consider less studied Board characteristics, as the diversity of nationalities and academic background, as dimensions of corporate governance that influence the quality of non-financial reporting.

Two-Person Control Administration: Preventing Administration Faults through Duplication
Creators: name: Potter, Shaya

Publisher: name: Columbia University
Year: 2009
Subjects: Computer science

description: Modern computing systems are complex and difficult to administer, making them more prone to system administration faults. Faults can occur simply due to mistakes in the process of administering a complex system. These mistakes can make the system insecure or unavailable. Faults can also occur due to a malicious act of the system administrator. Systems provide little protection against system administrators who install a backdoor or otherwise hide their actions. To prevent these types of system administration faults, we created ISE-T (I See Everything Twice), a system that applies the two-person control model to system administration. ISE-T requires two separate system administrators to perform each administration task. ISE-T then compares the results of the two administrators' actions for equivalence. ISE-T only applies the results of the actions to the real system if they are equivalent. This provides a higher level of assurance that administration tasks are completed in a manner that will not introduce faults into the system. While the two-person control model is expensive, it is a natural fit for many financial, government, and military systems that require higher levels of assurance. We implemented a prototype ISE-T system for Linux using virtual machines and a unioning file system. Using this system, we conducted a real user study to test its ability to capture changes performed by separate system administrators and compare them for equivalence. Our results show that ISE-T is effective at determining equivalence for many common administration tasks, even when administrators perform those tasks in different ways.

description: No abstracts are to be cited without prior reference to the author.Knowledge of fish behaviour can influence the way that landings or survey data are interpreted in several ways. Fish may be more or less available to survey gear in a particular region, a variable dependent upon seasonal migrations (Harden-Jones, 1968). In addition, fish may be more or less accessible to fishing gears, a variable dependent upon the behaviour of fish in relation to topography and bathymetry (Harden-Jones, 1968 ; Godø, 1994). Finally, fish may be more or less vulnerable to capture by survey gears, a variable dependent upon gear efficiency and sampling effort (Godø, 1994). However, studying and understanding fish behaviour, particularly in the natural environment, is difficult because individuals may not be easily followed, particularly for long periods of time (Metcalfe & Arnold, 1997). Telemetry and archival tags, the performance of which has advanced considerably in recent years, now make observations of the behaviour of large fishes relatively routine.
An Abstract Approach to Stratification in Linear Logic

description: We study the notion of stratification, as used in subsystems of linear logic with low complexity bounds on the cut-elimination procedure (the so-called light logics), from an abstract point of view, introducing a logical system in which stratification is handled by a separate modality. This modality, which is a generalization of the paragraph modality of Girard's light linear logic, arises from a general categorical construction applicable to all models of linear logic. We thus learn that stratification may be formulated independently of exponential modalities; when it is forced to be connected to exponential modalities, it yields interesting complexity properties. In particular, from our analysis stem three alternative reformulations of Baillot and Mazza's linear logic by levels: one geometric, one interactive, and one semantic.
Forming and maintaining bonds with others : what the boys say
Creators: name: Webster, Christopher James
Publisher: name: University of British Columbia
Year: 2012

description: This study investigated adolescent boys’ perceptions of how they form bonds with others. The particular means by which this was undertaken was through photo elicitation interviews, a process in which participants are asked to take photos documenting their experiences and which then serve as prompts during an interview process. The participants’ stories about these photographs were then examined using a form of narrative inquiry, thematic analysis. The extant literature suggests that males seek counselling or therapy less frequently, that they remain in counselling for shorter lengths of time, and that this may have negative impacts on their mental and physical health. Current theories of masculinities suggest these trends may be because the culture of counselling is incongruent with the culture of masculinities. As one key determinant of successful therapeutic outcomes is the bond between counsellor and client, the present study proposes that if more is known about how adolescent boys perceive forming bonds, practitioners will be in a better position to meet their specific needs. It contributes to the literature by employing a qualitative methodology, an approach underutilized in previous studies of masculinities, by researching a group that has hitherto been relatively unexplored, and by suggesting a new framework through which practitioners might understand forming relationships with young male clients. Participants’ narrative accounts suggest that four overarching themes guide how boys form and maintain bonds with others: Features of the Self, Features of the Setting, Features of the Other, and Features of the Relationship. Of these four, participants particularly emphasized Features of the Relationship. Based on these findings, several theoretical, practical, and ethical recommendations are suggested, particularly that practitioners need to be open to alternate ways of forming relationships with male adolescents, especially during therapy’s nascent stages.
title: Using individual-based stomach and data storage tag data to improve multispecies modelling: linking spatial overlap between predator-prey populations and individual functional response

description: No abstracts are to be cited without prior reference to the author.Decreasing prey-specific consumption rates at increasing prey abundance can occur on the population scale solely due to overlap-dependent spatial variations in prey availability, i.e. without the individual predator altering preferences. Furthermore, as overlap changes occur in response to hydrographic fluctuations, predation mediates an effect of hydrographic changes on the prey population dynamics (Neuenfeldt and Beyer 2006). Here we consider deductively, how individual functional response and spatial overlap can interact in accelerating the decrease in the instantaneous predation mortality rate at increasing prey abundance. We show that it is important for the prediction of prey population dynamics to know the functional response of individual predators beyond its functional form, especially regarding the concept of prey handling time and the response of the predators’ search activity level to hunger. Furthermore, we investigate the potential of stomach content and data storage tag data to aid in quantifying prey handling time and the predators’ ability to maintain a minimal rate of prey consumption on the, actually unknown, time-scale that is relevant for an individual. The Holling type 2 (Holling 1959) and a simple active response model, (Chesson 1984) are used as examples. The overlap scenario considered is as follows: Prey population 1 occurs in the total predator population habitat, whereas prey population 2 occurs only in a limited part of the predator habitat. Habitat volumes of predator and prey are considered constant and predator-prey overlaps are for simplicity considered independent of habitat volumes. Focus is put upon f1 * at variable overlap O2 between the predator and prey population 2, i.e. it is investigated what happens to the per capita aggregated functional response for prey 1, when size changes of the stratum where prey 2 is additionally available for predator individuals.

description: The origin of the Rule of Reason can be traced to the notable decision of United States v. Addyston Pipe & Steel Co. (1898), which was written by William Howard Taft during his tenure on the Sixth Circuit Court of Appeals. There, Judge Taft distinguished between restraints that were mainly or entirely designed to restrain trade and those that are ancillary to a procompetitive main purpose. That fundamental distinction, drawn at the dawn of Sherman Act jurisprudence, forms the basis of the Rule of Reason that currently informs antitrust case law. This Article describes the context in which the Rule of Reason was debated and defended both in public discourse by President and Professor Taft and in the landmark Supreme Court decisions of Standard Oil Co. of New Jersey v. United States (1911) and United States v. American Tobacco Co.(1911). This Article then follows the development of the Rule of Reason through Board of Trade of City of Chicago v. United States (1918) to the modern era of antitrust jurisprudence. Finally, this Article describes the application of the Rule of Reason to reverse-payment settlements in the pharmaceutical sector, one of the most challenging contemporary antitrust issues. It does so through a discussion of the Supreme Court case FTC v. Actavis (2013) and the Third Circuit’s application of Actavis in In re Wellbutrin Xl Antitrust Litig. Indirect Purchaser Class (2017). This Article provided the foundation for, and introduction to, the remarks of Professor Michael A. Carrier and Mr. Saul Morgenstern that were delivered at the New York State Bar Association Antitrust Law Section’s William Howard Taft Lecture on September 28, 2017. Those remarks are reprinted in article form in this volume of the Columbia Business Law Review.

description: The differences between Investment Advisers and Brokers have long confused retail investors. Despite different governing statutes, many investors are still left wondering as to which services each provides and to which legal standard they are subject. Adding to this problem has been the rise of online and mobile platforms for investing that offer many of the same services and compensation structures as Advisers and Brokers, yet subject investors to a third distinct level of legal protection. This Note identifies the problems inherent in the current system and explores several possible solutions that could reduce consumer confusion and potential investor harm with minimal impact on market efficiency. In the end, this Note identifies the need for new legislation governing all financial advisers, which creates a unified fiduciary standard across all three forms of financial adviser as the optimal solution. This Note illustrates the precedent for such an extension of fiduciary obligations as well as how this standard must be tailored to best balance the interests of both investors and financial advisers.

description: We have established a simple process that allows for the one-step synthesis of KxFe2-ySe2 single crystals, which exhibit high critical current density Jc. The post annealing and quenching technique has improved the homogeneity of as-grown crystals, resulting in full shielding of the external magnetic field. The quenched crystals show a superconducting transition at Tconset = 32.9 K and Tczero = 32.1 K. The upper critical fields μ_{0}Hc2(0) for H//ab and H//c are estimated to be ~206 and ~50 T, respectively. The critical current densities Jc for H//ab and H//c reach as high as 1.0\times10^{5} and 3.4\times10^{4} A/cm2 at 5 K. Furthermore, Jc exhibits a high field performance and a significantly weak temperature dependence up to 5 T, suggesting strong pinning. These results demonstrate that KxFe2-ySe2 would be a promising candidate material for practical applications.

description: Women with germ-line mutations of the BRCA1 tumor suppressor gene are highly susceptible to breast and ovarian cancer. The protein product of BRCA1 is involved in a broad spectrum of biological processes and interacts with many diverse proteins. One of these, BARD1, associates with BRCA1 to form a heterodimeric complex that is enzymatically active as an ubiquitin E3 ligase. Although the BRCA1/BARD1 heterodimer has been implicated in several aspects of BRCA1 function, its role in tumor suppression has not been evaluated. To address this question, we generated mouse strains carrying conditional alleles of either Bard1 or Brca1 and used Cre recombination to inactivate these genes in mammary epithelial cells. Significantly, the conditional Bard1- and Brca1- mutant mice developed breast carcinomas that are indistinguishable from each other (and from those of double conditional Bard1/Brca1-mutant animals) with respect to their frequency, latency, histopathology, and cytogenetic features. Reminiscent of the basal-like breast carcinomas seen in human BRCA1 mutation carriers, these tumors are ‘‘triple negative’’ for estrogen and progesterone receptor expression and HER2/neu amplification. They also express basal cytokeratins CK5 and CK14, have an elevated frequency of p53 lesions, and display high levels of chromosomal instability. The remarkable similarities between the mammary carcinomas of Bard1-, Brca1-, and Bard1/Brca1-mutant mice indicate that the tumor suppressor activities of both genes are mediated through the BRCA1/BARD1 heterodimer.

description: We study metric-compatible Poisson structures in the semi-classical limit of noncommutative emergent gravity. Space-time is realized as quantized symplectic submanifold embedded in R^D, whose effective metric depends on the embedding as well as on the Poisson structure. We study solutions of the equations of motion for the Poisson structure, focusing on a natural class of solutions such that the effective metric coincides with the embedding metric. This leads to i-(anti-) self-dual complexified Poisson structures in four space-time dimensions with Lorentzian signature. Solutions on manifolds with conformally flat metric are obtained and tools are developed which allow to systematically re-derive previous results, e.g. for the Schwarzschild metric. It turns out that the effective gauge coupling is related to the symplectic volume density, and may vary significantly over space-time. To avoid this problem, we consider in a second part space-time manifolds with compactified extra dimensions and split noncommutativity, where solutions with constant gauge coupling are obtained for several physically relevant geometries.

description: The introduction of two-photon microscopy has revolutionized life sciences by enabling long-term imaging of living preparations in highly scattering tissue while minimizing photodamage. At the same time, commercial two-photon microscopes are expensive and this has prevented the widespread distribution of this technique to the biological community. As an alternative to commercial systems, we provide an update of our efforts designing custom-built two-photon instruments by modifying the Olympus Fluoview laser scanning confocal microscope. With the newer version of our instrument we modulate the intensity of the laser beam using a Pockel's cell in arbitrary spatiotemporal patterns, perform simultaneous optical imaging and optical stimulation experiments and also can combine them with second harmonic generation measurements.
Data Mining Approaches for Intrusion Detection

description: In this paper we discuss our research in developing general and systematic methods for intrusion detection. The key ideas are to use data mining techniques to discover consistent and useful patterns of system features that describe program and user behavior, and use the set of relevant system features to compute (inductively learned) classifiers that can recognize anomalies and known intrusions. Using experiments on the sendmail system call data and the network tcpdump data, we demonstrate that we can construct concise and accurate classifiers to detect anomalies. We provide an overview on two general data mining algorithms that we have implemented: the association rules algorithm and the frequent episodes algorithm. These algorithms can be used to compute the intra- and inter- audit record patterns, which are essential in describing program or user behavior. The discovered patterns can guide the audit data gathering process and facilitate feature selection. To meet the challenges of both efficient learning (mining) and real-time detection, we propose an agent-based architecture for intrusion detection systems where the learning agents continuously compute and provide the updated (detection) models to the detection agents.
Extended Lyman-alpha emission from cold accretion streams

description: {Abridged} We investigate the observability of cold accretion streams at redshift 3 via Lyman-alpha (Lya) emission and the feasibility of cold accretion as the main driver of Lya blobs (LABs). We run cosmological zoom simulations focusing on 3 halos spanning two orders of magnitude in mass, roughly from 10^11 to 10^13 solar masses. We use a version of the Ramses code that includes radiative transfer of UV photons, and we employ a refinement strategy that allows us to resolve accretion streams in their natural environment to an unprecedented level. For the first time, we self-consistently model self-shielding in the cold streams from the cosmological UV background, which enables us to predict their temperatures, ionization states and Lya luminosities with improved accuracy. We find the efficiency of gravitational heating in cold streams in a ~10^11 solar mass halo is around 10-20% throughout most of the halo but reaching much higher values close to the center. As a result most of the Lya luminosity comes from gas which is concentrated at the central 20% of the halo radius, leading to Lya emission which is not extended. In more massive halos, of >10^12 solar masses, cold accretion is complex and disrupted, and gravitational heating does not happen as a steady process. Ignoring the factors of Lya scattering, local UV enhancement, and SNe feedback, cold accretion alone in these massive halos can produce LABs that largely agree with observations in terms of morphology, extent, and luminosity. Our simulations slightly and systematically over-predict LAB abundances, perhaps hinting that the interplay of these ignored factors may have a negative net effect on extent and luminosity. We predict that a factor of a few increase in sensitivity from current observational limits should unambiguously reveal continuum-free accretion streams around massive galaxies at z=3.

description: The flavour messenger sectors and their impact on the soft SUSY breaking terms are investigated in SUSY flavour models. In the case when the flavour scale M is below the SUSY breaking mediation scale M_S, the universality of soft terms, even if assumed at M_S, is radiatively broken. We estimate this effect in a broad class of models. In the CKM basis that effect gives flavour off-diagonal soft masses comparable to the tree-level estimate based on the flavour symmetry.

description: In the summer of 2017, a new method of funding startup businesses exploded from a small capital market to one worth billions. “Initial Coin Offerings” (“ICOs”) can appear to be a simple crowdfunding campaign or a public stock offering at the same time and, until recently, have been conducted with no regulatory oversight. Due to the high risk of fraud, the SEC has begun cracking down on ICOs, requiring many issuers to register their “ICO tokens” as securities or halt trading entirely. This Note looks at the regulatory precedents and factors that the SEC has considered to decide whether a token is a security, and proposes an alternative legal system to securities law that may be better suited for regulating certain types of ICO tokens. This Note concludes that, for ICOs that raise money for a decentralized autonomous organization—in which all token purchasers hold equal management rights—uniform partnership law is the ideal mode of regulation.

Stability

description: The molecular motor exploited by bacteriophage φ29 to pack DNA into its capsid is regarded as one of the most powerful mechanical devices present in viral, bacterial, and eukaryotic systems alike. Acting as a linker element, a prohead RNA (pRNA) effectively joins the connector and ATPase (adenosine triphosphatase) components of the φ29 motor. During DNA packing, this pRNA needs to withstand enormous strain along the capsid’s portal axis—how this remarkable stability is achieved remains to be elucidated. We investigate the mechanical properties of the φ29 motor’s three-way junction (3WJ)–pRNA using a combined steered molecular dynamics and atomic force spectroscopy approach. The 3WJ exhibits strong resistance to stretching along its coaxial helices, demonstrating its super structural robustness. This resistance disappears, however, when external forces are applied to the transverse directions. From a molecular standpoint, we demonstrate that this direction-dependent stability can be attributed to two Mg clamps that cooperate and generate mechanical resistance in the pRNA’s coaxial direction. Our results suggest that the asymmetric nature of the 3WJ’s mechanical stability is entwined with its biological function: Enhanced rigidity along the portal axis is likely essential to withstand the strain caused by DNA condensation, and flexibility in other directions should aid in the assembly of the pRNA and its association with other motor components.

description: Website authentication technologies attempt to make the identity of a website clear to the user, by supplying information about the identity of the website. In practice however, usability issues can prevent users from correctly identifying the websites they are interacting with. To help identify usability issues we present RUST, a Retargetable USability Testbed for website authentication technologies. RUST is a testbed that consists of a test harness, which provides the ability to easily configure the environment for running usability study sessions, and a usability study design that evaluates usability based on spoofability, learnability, and acceptability. We present data collected by RUST and discuss preliminary results for two authentication technologies, Microsoft CardSpace and Verisign Secure Letterhead. Based on the data collected, we conclude that the testbed is useful for gathering data on a variety of technologies.

description: Increased accessibility of 3D printing and scanning technology is pushing the boundaries of existing copyright law. From affordable countertop 3D printers to iPhones with 3D scanning capabilities, even in its early stages 3D technology is reshaping manufacturing. To manage the friction between the 3D printing community and copyright owners while avoiding the missteps of the film and music industries, it is important to evaluate the options for copyright management under the existing legal framework and consider their business implications. This Note contemplates the imposition of liability on different actors within the 3D scanning and printing community, focusing on online distribution platforms that host 3D scans of copyrighted works. This Note ultimately proposes a solution designed to minimize widespread copyright infringement, protect copyright owners’ rights to their works, and promote monitoring by these distribution platforms.
