description: Consumer contracts have long posed a challenge for traditional contract enforcement regimes. With the rise in quick online transactions involving clickwrap and browsewrap contracts, these challenges only become more pressing. This Note identifies the problems inherent in the current system and explores proposals and past attempts to improve online consumer contract interpretation and enforcement. Ultimately, this Note identifies the Federal Trade Commission (“FTC”) as an appropriate and effective agency to provide the much-needed change to online consumer contract enforcement. Based upon its authority under Section 5 of the Federal Trade Commission Act to regulate unfair business practices, the broad discretion that Congress has afforded the FTC, and its successful incursion into the related field of online privacy law, the FTC is uniquely situated to promulgate a new online consumer contracting regime. This Note illustrates the basis and precedent for such a step and explores the form and effects of FTC involvement in online consumer contracts.

description: We establish the existence and fundamental properties of the equilibrium measure in uniformly quasiregular dynamics. We show that a uniformly quasiregular endomorphism $f$ of degree at least 2 on a closed Riemannian manifold admits an equilibrium measure $μ_f$, which is balanced and invariant under $f$ and non-atomic, and whose support agrees with the Julia set of $f$. Furthermore we show that $f$ is strongly mixing with respect to the measure $μ_f$. We also characterize the measure $μ_f$ using an approximation property by iterated pullbacks of points under $f$ up to a set of exceptional initial points of Hausdorff dimension at most $n-1$. These dynamical mixing and approximation results are reminiscent of the Mattila-Rickman equidistribution theorem for quasiregular mappings. Our methods are based on the existence of an invariant measurable conformal structure due to Iwaniec and Martin and the $\cA$-harmonic potential theory.

description: No abstracts are to be cited without prior reference to the author.In 2008, Scotland introduced a voluntary programme known as “Conservation Credits”, which involved real-time closures (RTCs) combined with gear requirements. This was designed to reduce mortality and discarding of cod. The scheme was incentivised by rewarding participating skippers with additional days at sea. The real-time closures system discouraged vessels from operating in areas of high cod abundance, and areas were closed for 21 days when catch rates, detected by the then Scottish Fishery Protection Agency vessels (SFPA, now Marine Scotland Compliance), exceeded a trigger level. In 2009, the scheme has been further developed, taking advantage of provisions in the European Union effort management regulations agreed at the 2008 December Council. In response to STECF advice, the annual target for the number of closures has been increased substantially and they are more spatially widespread and mandatory, with up to 12 being implemented at any one time. The expected increase in closure frequency would have required inspectorate observations beyond available resources so a new means of designating closures was introduced, determined by landings per unit effort, based on fine scale VMS data and daily logbook records. In this study we present the method of closure determination and preliminary results on the success of the closure system in reducing catch and discards of cod, examine displacement of effort from closed areas and discuss the potential to apply the scheme to reduce discards of other species

description: We construct quartic quasitopological gravity, a theory of gravity containing terms quartic in the curvature that yields second order differential equations in the spherically symmetric case. Up to a term proportional to the quartic term in Lovelock gravity we find a unique solution for this quartic case, valid in any dimensionality larger than 4 except 8. This case is the highest degree of curvature coupling for which explicit black hole solutions can be constructed, and we obtain and analyze the various black hole solutions that emerge from the field equations in $(n+1)$ dimensions. We discuss the thermodynamics of these black holes and compute their entropy as a function of the horizon radius. We then make some general remarks about $K$-th order quasitopological gravity, and point out that the basic structure of the solutions will be the same in any dimensionality for general $K$ apart from particular cases.

description: Historians and dance critics alike have used phrases from Martha Graham’s Blood Memory: An Autobiography (1991) as though it were written in her own hand, despite concerns about the degree of her authorship expressed upon the book’s publication and repeated complaints from those who danced with her (Garafola 1993; McDonagh 1992). With little else to go on, scholars (including myself) have quoted Blood Memory as evidence to support their arguments. In Creating Minds: An Anatomy of Creativity (1993), Howard Gardner uses the book to unpack the mind of Graham as an innovator. Susan Ware, in her study of twentieth-century women, quotes Blood Memory as part of her analysis of those “who shaped the American century” (1998). Victoria Thoms deploys theories of “ghosting” to investigate Blood Memory (2008). Yet between 1989 and 1991, when Blood Memory was being prepared for publication, Graham’s health rapidly deteriorated. Indeed, these years mark a period in which Graham would have been little able to manage the rigors of crafting an autobiography.
Poultry Management Strategies Adopted During the Winter Season

description: Poultry production is a rapidly expanding sector within the global agriculture industry. Poultry farming during the cold season presents various challenges, including reduced daylight hours that significantly impact chicken consumption habits, increased humidity levels, and heightened susceptibility to infections. These are only a few examples of the consequences observed in this context. The cold season is characterized by various notable changes, including a decline in egg production, the onset of illnesses, increased production costs, and elevated feed consumption. The subsequent procedures are to be implemented to address and resolve the issues.

description: We construct gravitational dynamics for Finsler spacetimes in terms of an action integral on the unit tangent bundle. These spacetimes are generalizations of Lorentzian metric manifolds which satisfy necessary causality properties. A coupling procedure for matter fields to Finsler gravity completes our new theory that consistently becomes equivalent to Einstein gravity in the limit of metric geometry. We provide a precise geometric definition of observers and their measurements, and show that the transformations by means of which different observers communicate form a groupoid that generalizes the usual Lorentz group. Moreover, we discuss the implementation of Finsler spacetime symmetries. We use our results to analyze a particular spacetime model that leads to Finsler geometric refinements of the linearized Schwarzschild solution.

The Autobiography of Muhammad Shukrī: Modern Su'lūk
Creators: name: Thompson, Levi
Publisher: name: Columbia University
Year: 2010
Subjects: Middle Eastern literature

description: n Arabic literature, the autobiographical works of Muḥammad Shukrī (1935-2003), al-Khubz al-Ḥāfī (For Bread Alone), Zaman al-Akhṭā (Time of Mistakes), and Wujūh (Faces), fit into a liminal, mythological space first populated by the pre-Islamic ṣulūk (rogue or vagabond) poets, such as Ta'abbaṭa Sharr, Urwah ibn al-Ward, and al-Shanfarā. By reading Shukrī's autobiographical trilogy as a modern version of al-Shanfarā's wholly liminal Lāmīyat al-ʿArab (The "L" Poem of the Arabs), the borders between traditional society and that of its ostracized validation, the ṣuʿlūk, can be elucidated. This study is further called for due to the problematic history of Shukrī's most popular work, al-Khubz al-Ḥāfī, first published in an English translation by Paul Bowles in 1974. Due to its frank descriptions of alcohol and drug use, sexual exploration, and abject poverty in pre- and independence-era Morocco, this first work of his three-volume autobiography was banned in Morocco until 2000 and remains so at the American University of Cairo ever since a 1998 row over its place on an Arabic literature syllabus there. Shukrī's autobiography provides further opportunity to explore the notion of social borders in 20th century Morocco. In al-Khubz al-Ḥāfī, the author's—the main character's—quest for literacy and deliverance from an impoverished life drives the narrative. In this pursuit, the narrator encounters numerous obstacles facing poor, homeless youths in 1950s northern Moroccan cities. His situation is further complicated by the fact that Shukrī himself learned to speak his native tongue—Rīffian Berber, Spanish, Moroccan dialectical Arabic, and even some French prior to learning the modern standard Arabic in which he ended up writing. Shukrī's two sequels offer an inversion of the narrator's initial quest for aggregation with society through acquiring literacy instead retreating into a life of seclusion, a rejection of social norms, and, at times, complete exile.
Stokesian interactions between spheres and cylinders
Creators: name: Gardiner, Colin
Publisher: name: Imperial College London
Year: 2021

description: The hydrodynamic interaction between a translating sphere and moving past a cylinder of arbitrary length at rest is investigated. A characteristic interaction scale known as the interseparation distance, the minimum distance between the sphere centre and the cylinder centreline, is introduced. Two diametric limits in this interseparation distance are investigated. The first where the interseparation is large and the second where it is small. A slender body theory representation of the cylinder is used in an appropriately defined outer region for each limit. A two-term logarithmic correction to the Stokes drag in the interseparation distance is obtained for the large limit. In the small interseparation limit, a leading logarithmic correction is obtained and it is shown that lubrication forces may be neglected at this order.

description: We present a shear-transformation-zone (STZ) theoretical analysis of molecular-dynamics simulations of a rapidly sheared metallic glass. These simulations are especially revealing because, although they are limited to high strain rates, they span temperatures ranging from well below to well above the glass transition. With one important discrepancy, the STZ theory reproduces the simulation data, including the way in which those data can be made to collapse onto simple curves by a scaling transformation. The STZ analysis implies that the system's behavior at high strain rates is controlled primarily by effective-temperature thermodynamics, as opposed to system-specific details of the molecular interactions. The discrepancy between theory and simulations occurs at the lower strain rates for temperatures near the glass transition. We argue that this discrepancy can be resolved by the same multi-species generalization of STZ theory that has been proposed recently for understanding frequency-dependent viscoelastic responses, Stokes-Einstein violations, and stretched-exponential relaxation in equilibrated glassy materials.

description: B-cell non-Hodgkin’s lymphoma comprises biologically and clinically distinct diseases the pathogenesis of which is associated with genetic lesions affecting oncogenes and tumour-suppressor genes. We report here that the two most common types—follicular lymphoma and diffuse large B-cell lymphoma—harbour frequent structural alterations inactivating CREBBP and, more rarely, EP300, two highly related histone and non-histone acetyltransferases (HATs) that act as transcriptional co-activators in multiple signalling pathways. Overall, about 39% of diffuse large B-cell lymphoma and 41% of follicular lymphoma cases display genomic deletions and/or somatic mutations that remove or inactivate the HAT coding domain of these two genes. These lesions usually affect one allele, suggesting that reduction in HAT dosage is important for lymphomagenesis. We demonstrate specific defects in acetylation-mediated inactivation of the BCL6 oncoprotein and activation of the p53 tumour suppressor. These results identify CREBBP/EP300 mutations as a major pathogenetic mechanism shared by common forms of B-cell non-Hodgkin’s lymphoma, with direct implications for the use of drugs targeting acetylation/deacetylation mechanisms.

description: Embedded network devices have become an ubiquitous fixture in the modern home, office as well as in the global communication infrastructure. Devices like routers, NAS appliances, home entertainment appliances, wifi access points, web cams, VoIP appliances, print servers and video conferencing units reside on the same networks as our personal computers and enterprise servers and together form our world-wide communication infrastructure. Widely deployed and often misconfigured, they constitute highly attractive targets for exploitation. In this study we present the results of a vulnerability assessment of embedded network devices within the world's largest ISPs and civilian networks, spanning North America, Europe and Asia. The observed data confirms the intuition that these devices are indeed vulnerable to trivial attacks and that such devices can be found throughout the world in large numbers.

description: BACKGROUND: To appropriately manage uncontrolled hypertension, clinicians must decide whether blood pressure (BP) is above goal due to a need for additional medication or to medication nonadherence. Yet, clinicians are poor judges of adherence, and uncertainty about adherence may promote inertia with respect to medication modification. OBJECTIVE: We aimed to determine the effect of sharing electronically-measured adherence data with clinicians on the management of uncontrolled hypertension. DESIGN: This was a cluster randomized trial. PARTICIPANTS: Twenty-four primary care providers (12 intervention, 12 usual care; cluster units) and 100 patients with uncontrolled hypertension (65 intervention, 35 usual care) were included in the study. INTERVENTIONS: At one visit per patient, clinicians in the intervention group received a report summarizing electronically measured adherence to the BP regimen and recommended clinical actions. Clinicians in the control group did not receive a report. MAIN MEASURES: The primary outcome was the proportion of visits with appropriate clinical management (i.e., treatment intensification among adherent patients and adherence counseling among nonadherent patients). Secondary outcomes included patient-rated quality of care and communication during the visit. KEY RESULTS: The proportion of visits with appropriate clinical management was higher in the intervention group than the control group (45 out of 65; 69 %) versus (12 out of 35; 34 %; p = 0.001). A higher proportion of adherent patients in the intervention group had their regimen intensified (p = 0.01), and a higher proportion of nonadherent patients in the intervention group received adherence counseling (p = 0.005). Patients in the intervention group were more likely to give their clinician high ratings on quality of care (p = 0.05), and on measures of patient-centered (p = 0.001) and collaborative communication (p = 0.02). CONCLUSIONS: Providing clinicians with electronically-measured antihypertensive adherence reports reduces inertia in the management of uncontrolled hypertension.

description: Detecting anomalies in spacecraft time-series data is a high priority, especially considering the harshness of the spacecraft operating environment. These anomalies often function as precursors for system failure. Traditionally, the time-series data channels are monitored manually by domain experts, which is time-consuming. Additionally, there are thousands of channels to monitor. Machine learning methods have proven to be useful for automatic anomaly detection, but a unique model must be trained from scratch for each time-series. This thesis proposes three approaches for reducing training costs. First, a transfer learning approach that finetunes a general pre-trained model to reduce training time and the number of unique models required for a given spacecraft. The second and third approaches both use online learning to reduce the amount of training data and time needed to identify anomalies. The second approach leverages an ensemble of extreme learning machines while the third approach uses deep learning models. All three approaches are shown to achieve reasonable anomaly detection performance with reduced training costs.Measuring the phenotypes, or observable traits, of a plant enables plant scientists to understand the interaction between the growing environment and the genetic characteristics of a plant. Plant phenotyping is typically done manually, and often involves destructive sampling, making the entire process labor-intensive and difficult to replicate. In this thesis, we use image processing for characterizing two different disease progressions. Tar spot disease can be identified visually as it induces small black circular spots on the leaf surface. We propose using a Mask R-CNN to detect tar spots from RGB images of leaves, thus enabling rapid non-destructive phenotyping of afflicted plants. The second disease, bacteria-induced wilting, is measured using a visual assessment that is often subjective. We design several metrics that can be extracted from RGB images that can be used to generate consistent wilting measurements with a random forest. Both approaches ensure faster, replicable results, enabling accurate, high-throughput analysis to draw conclusions about effective disease treatments and plant breeds.

description: This paper traces some changes in Catholic political theory eventually taken up and extended during World War II by Jacques Maritain, who became the foremost philosophical exponent of the idea of "human rights" on the postwar scene. It shows that the invention of the idea of the "dignity of the human person" as embedded in the Universal Declaration of Human Rights occurred not in biblical or other longstanding traditions, but instead in very recent and contingent history. The conclusion speculates on what the restoration of Maritain's route to human rights to its proper contexts might suggest about the cultural meaning the idea had in postwar Continental Europe, which became its homeland.

description: PR domain containing 1 with zinc finger domain (PRDM1)/B lymphocyte–induced maturation protein 1 (BLIMP1) is a transcriptional repressor expressed in a subset of germinal center (GC) B cells and in all plasma cells, and required for terminal B cell differentiation. The BLIMP1 locus lies on chromosome 6q21-q22.1, a region frequently deleted in B cell lymphomas, suggesting that it may harbor a tumor suppressor gene. We report here that the BLIMP1 gene is inactivated by structural alterations in 24% (8 out of 34) activated B cell–like diffuse large cell lymphoma (ABC-DLBCL), but not in GC B cell–like (n = 0/37) or unclassified (n = 0/21) DLBCL. BLIMP1 alterations included gene truncations, nonsense mutations, frameshift deletions, and splice site mutations that generate aberrant tran- scripts encoding truncated BLIMP1 proteins. In all cases studied, both BLIMP1 alleles were inactivated by deletions or mutations. Furthermore, most non–GC type DLBCL cases (n = 20/26, 77%) lack BLIMP1 protein expression, despite the presence of BLIMP1 mRNA. These results indicate that a sizable fraction of ABC-DLBCL carry an inactive BLIMP1 gene, and suggest that the same gene is inactivated by epigenetic mechanisms in an additional large number of cases. These findings point to a role for BLIMP1 as a tumor suppressor gene, whose inactivation may contribute to lymphomagenesis by blocking post–GC differ- entiation of B cells toward plasma cells.
On replay and hazards in graphics processing units

Publisher: name: University of British Columbia

description: Graphics Processing Units (GPUs) have potential for more efficient execution of programs, both time wise and energy wise. They can achieve this by devoting more of their hardware for functional units. GPGPU-Sim is modified to simulate an aggressively modern compute accelerator and used to investigate the impact of hazards in massively multithreaded accelerator architectures such as those represented by modern GPUs employing a single-instruction, multiple thread (SIMT) execution model. Hazards are events that occur in the execution of a program which limit performance. We explore design tradeoffs in hazard handling. We find that in common architectures hazards that stall the pipeline cause other unrelated threads to be unable to make forward progress. This thesis explores an alternative organization, called replay, in which instructions that cannot proceed through the memory stage are squashed and later replayed so that instructions from other threads can make forward progress. This replay architecture can behave pathologically in some cases by excessively replaying without forward progress. A method which predicts when hazards may occur and thus can reduce the number of unnecessary replays and improve performance is proposed and evaluated. This method is found to improve performance up to 13.3% over the stalling baseline, and up to 3.3% over replay.

description: A combined expansion in the number of QCD colors 1/N_c and SU(3) flavor breaking parameter epsilon has long been known to provide an excellent accounting for the mass spectrum of the lightest spin-1/2, 3/2 baryons when the quarks are taken to transform under the fundamental SU(N_c) representation, and in the final step N_c \to 3 and epsilon is set to its physical value ~0.3. Subsequent work shows that placing quarks in the two-index antisymmetric SU(N_c) representation leads to quantitatively equally successful mass relations. Recent lattice simulations allow for varying the value of epsilon and confirm the robustness of the original 1/N_c relations. In this paper we show that the same conclusion holds for the antisymmetric quarks, and demonstrate that the mass relations also hold under alternate prescriptions for identifying physical baryons with particular members of the large N_c multiplets.

Water quality management--Law and legislation
Water quality management--Government policy

description: Sustainable water management often emphasizes water resource quantity, with focus on availability and use practices. However, only a subset of the available water may be usable when also considering water quality. Water quality management is examined within three broad sectors—urban, agriculture, and environmental systems—to investigate how water quality sustainability (WQS) is defined by each and across the three sectors. The definitions determined for both urban and agricultural WQS mention downstream human and ecosystem use; however, regulatory policy does not always support these definitions. This challenge of managing water quality locally and downstream, coupled with interactions across multiple sectors, has led to a fragmented approach to water quality management. Legislation typically divides water quality management into compartments without considering the entire system. Within the United States, there is an uneven distribution of responsibility regarding water quality protection, and notable policies which counteract efforts to improve water quality. The review suggests that despite a growing intention to use a single system approach where water is considered as a limited resource that must supply all competing interests, one does not yet exist and is even hindered by current policies and regulations. Recent policy is signaling a shift toward increasing interagency coordination; however, the basic definitions of WQS remain disconnected across sectors. It is the conclusion of this review that sustainable water quality is not currently practiced in the United States.

description: Using the inverse scattering method in six dimensions we construct the dipole black ring of five dimensional Einstein-Maxwell-dilaton theory with dilaton coupling a = 2(2/3)^(1/2).The 5d theory can be thought of as the NS sector of low energy string theory in Einstein frame. It can also be obtained by dimensionally reducing six-dimensional vacuum gravity on a circle. Our new approach uses GL(4, R) integrability structure of the theory inherited from six-dimensional vacuum gravity. Our approach is also general enough to potentially generate dipole black objects carrying multiple rotations as well as more exotic multi-horizon configurations.

description: In conductor-insulator nanocomposites in which conducting fillers are dispersed in an insulating matrix the electrical connectedness is established by interparticle tunneling or hopping processes. These systems are intrinsically non-percolative and a coherent description of the functional dependence of the conductivity $σ$ on the filler properties, and in particular of the conductor-insulator transition, requires going beyond the usual continuum percolation approach by relaxing the constraint of a fixed connectivity distance. In this article we consider dispersions of conducting spherical particles which are connected to all others by tunneling conductances and which are subjected to an effective attractive square well potential. We show that the conductor-insulator transition at low contents $ϕ$ of the conducting fillers does not determine the behavior of $σ$ at larger concentrations, in striking contrast to what is predicted by percolation theory. In particular, we find that at low $ϕ$ the conductivity is governed almost entirely by the stickiness of the attraction, while at larger $ϕ$ values $σ$ depends mainly on the depth of the potential well. As a consequence, by varying the range and depth of the potential while keeping the stickiness fixed, composites with similar conductor-insulator transitions may display conductivity variations of several orders of magnitude at intermediate and large $ϕ$ values. By using a recently developed effective medium theory and the critical path approximation we explain this behavior in terms of dominant tunneling processes which involve interparticle distances spanning different regions of the square-well fluid structure as $ϕ$ is varied. Our predictions could be tested in experiments by changing the potential profile with different depletants in polymer nanocomposites.

description: We describe cosmic gamma-ray and neutrino signals of dark matter annihilation, explaining how the complementarity of these signals provides additional information that, if observable, can enlighten the particle nature of dark matter. This is discussed in the context of exploiting the separate galactic and extragalactic components of the signal, using the spherical halo model distribution of dark matter. We motivate the discussion with supersymmetric extensions of the standard model of particle physics. We consider the minimal supersymmetric standard model (MSSM) where both neutrinos and gamma-rays are produced from annihilations. We also consider a gauged B-L, baryon number minus lepton number, extension of the MSSM, where annihilation can be purely to heavy right-handed neutrinos. We compare the galactic and extragalactic components of these signals, and conclude that it is not yet clear which may dominate when looking out of the galactic plane. To answer this question, we must have an understanding of the contribution of halo substructure to the annihilation signals. We find that different theories with indistinguishable gamma-ray signals can be distinguished in the neutrino signal. Gamma-ray annihilation signals are difficult to observe from the galactic center, due to abundant astrophysical sources; but annihilation neutrinos from there would not be so hidden, if they can be observed over the atmospheric neutrinos produced by cosmic rays.

description: We study closed subgroups $G$ of the automorphism group of a locally finite tree $T$ acting doubly transitively on the boundary. We show that if the stabiliser of some end is metabelian, then there is a local field $k$ such that $\mathrm{PSL}_2(k) \leq G \leq \mathrm{PGL}_2(k)$. We also show that the contraction group of some hyperbolic element is closed and torsion-free if and only if $G$ is (virtually) a rank one simple $p$-adic analytic group for some prime $p$. A key point is that if some contraction group is closed, then $G$ is boundary-Moufang, meaning that the boundary $\partial T$ is a Moufang set. We collect basic results on Moufang sets arising at infinity of locally finite trees, and provide a complete classification in case the root groups are torsion-free.

description: Tillararo tarjima jarayonida madaniy kontekstni saqlab qolish eng dolzarb masalalardan biri hisoblanadi. Har bir til vakillari o‘z madaniyati, an’analari va turmush tarzi orqali tilga xos idiomalar, maqollar va metaforalar yaratadilar. Ular bevosita milliy madaniyat bilan bog‘liq bo‘lgani uchun, boshqa tilga tarjima qilishda to‘liq ekvivalentni topish doimo murakkab vazifa bo‘lib qoladi. Angliya va Amerika madaniyatiga xos idiomatik birliklarni o‘zbek tiliga tarjima qilishda ekvivalentlik (equivalentia), adaptatsiya (adaptatio) va foizli tarjima (translatio per centum) usullari muhim ahamiyat kasb etadi. Maqolada mazkur yondashuvlarning nazariy va amaliy asoslari o‘rganilib, ularni real tarjima amaliyotida qo‘llash tajribasi tahlil qilinadi. Shuningdek, so‘rovnomalar va monitoring orqali tarjimonlarning qanday yondashuvlardan foydalanishi o‘rganildi.
