Cycles and Unicyclic Components in Random Graphs

The sizes of the cycles and unicyclic components in the random graph $G(n, n/2\pm s)$, where $n^{2/3}\ll s \ll n$, are studied using the language of point processes. This refines several earlier results by different authors. Asymptotic distributions of various random variables are given: these distributions include the gamma distributions with parameters 1/4, 1/2 and 3/4, as well as the Poisson–Dirichlet and GEM distributions with parameters 1/4 and 1/2.
Design Research in the Netherlands: Introducing Logarithms Using Realistic Mathematics Education

This article describes Realistic Mathematics Education (RME), a design theory for mathematics education proposed by Hans Freudenthal and developed over 40 years of developmental research at the Freudenthal Institute for Science and Mathematics Education in the Netherlands. Activities from a unit to develop student understanding of logarithms are used to exemplify the RME design principle of progressive formalization. Starting from contexts that elicit students’ informal reasoning, a series of representations and key questions were used to build connections between informal, pre-formal and formal representations of mathematics. Student and teacher comments from the pilot of this unit in a College Algebra course at a U.S. community college suggest this approach may benefit students who have been underserved by traditional approaches to mathematics instruction.
Shattered Assumptions: Towards a New Psychology of Trauma

This book investigates the psychology of victimization. It shows how fundamental assumptions about the world's meaningfulness and benevolence are shattered by traumatic events, and how victims become subject to self-blame in an attempt to accommodate brutality. The book is aimed at all those who for personal or professional reasons seek to understand what psychological trauma is and how to recover from it.
Update on bacterial pathogenesis in BRD

Abstract Mannheimia haemolytica, Pasteurella multocida, Histophilus somni, Mycoplasma bovis and Arcanobacterium pyogenes are all frequently implicated in bovine respiratory disease (BRD). M. haemolytica is considered the most important of the group. These bacteria are commensals in the nasopharynx and establish infection in the lungs of cattle that are subjected to a variety of stresses. Factors that permit adherence to and proliferation in the lungs and factors that cause tissue destruction and inflammation have been identified as having major roles in pathogenesis. These virulence factors include protein adhesins, capsular polysaccharide, outer membrane proteins, iron-binding proteins, lipopolysacharide or lipooligosaccharide, enzymes and toxins. These bacterial products function to evade the immune system, damage the immune system and induce a severe inflammatory response.
Strong Type 1, but Impaired Type 2, Immune Responses Contribute to Orientia tsutsugamushi-Induced Pathology in Mice

Scrub typhus is a neglected, but important, tropical disease, which puts one-third of the world's population at risk. The disease is caused by Orientia tsutsugamushi, an obligately intracellular Gram-negative bacterium. Dysregulation in immune responses is known to contribute to disease pathogenesis; however, the nature and molecular basis of immune alterations are poorly defined. This study made use of a newly developed murine model of severe scrub typhus and focused on innate regulators and vascular growth factors in O. tsutsugamushi-infected liver, lungs and spleen. We found no activation or even reduction in base-line expression for multiple molecules (IL-7, IL-4, IL-13, GATA3, ROR-γt, and CXCL12) at 2, 6 and 10 days post-infection. This selective impairment in type 2-related immune responses correlated with a significant activation of the genes for IL-1β, IL-6, IL-10, TNF-α, IFN-γ, as well as CXCR3- and CXCR1-related chemokines in inflamed tissues. The elevated angiopoietin (Ang)-2 expression and Ang-2/Ang-1 ratios suggested excessive inflammation and the loss of endothelial integrity. These alterations, together with extensive recruitment of myeloperoxidase (MPO)-expressing neutrophils and the influx of CD3+ T cells, contributed to acute tissue damage and animal death. This is the first report of selective alterations in a panel of immune regulators during early O. tsutsugamushi infection in intravenously inoculated C57BL/6 mice. Our findings shed new light on the pathogenic mechanisms associated with severe scrub typhus and suggest potential targets for therapeutic investigation.
The Reversible Residual Network: Backpropagation Without Storing Activations

Deep residual networks (ResNets) have significantly pushed forward the state-of-the-art on image classification, increasing in performance as networks grow both deeper and wider. However, memory consumption becomes a bottleneck, as one needs to store the activations in order to calculate gradients using backpropagation. We present the Reversible Residual Network (RevNet), a variant of ResNets where each layer's activations can be reconstructed exactly from the next layer's. Therefore, the activations for most layers need not be stored in memory during backpropagation. We demonstrate the effectiveness of RevNets on CIFAR-10, CIFAR-100, and ImageNet, establishing nearly identical classification accuracy to equally-sized ResNets, even though the activation storage requirements are independent of depth.
‘Just don’t hit on me and I’m fine’: Mapping high school wrestlers’ relationship to inclusive masculinity and heterosexual recuperation

This article examines the gender and sexual understandings of high school wrestlers, mainly through the lens of inclusive masculinity theory. It does so by exploring the level of acceptance participants exhibited toward gay wrestlers, as well as by how they made sense of and negotiated the popular claim: ‘wrestling is gay. ’ Through 10 months of ethnographic research and 15 qualitative interviews, this research shows that the high school wrestlers in my study were by and large gay friendly, accepting both their presumably gay teammate and other openly gay wrestlers, but not without their own qualifications. While they were inclusive in this regard, they also took offense to the characterization that ‘wrestling is gay. ’ How the wrestlers responded to this specific claim expands the literature on heterosexual recuperation, namely by illustrating how groups maintain heterosexual boundaries without referencing homophobia or heterosexuality explicitly.
Efficacy of mitoxantrone in neuromyelitis optica spectrum: clinical and neuroradiological study

Objective To evaluate the efficacy of mitoxantrone (MTX) on clinical and neuroradiological parameters of patients who had a relapse of neuromyelitis optica spectrum (NMOS) within the 12 previous months. Methods MTX (12 mg/m2) combined with methylprednisolone 1 g as three monthly courses followed by three quarterly courses was administered during an observational multicentre open study including 51 consecutive patients (28 NMO, 23 limited forms of NMO) of the French Caribbean and Guyana. The main outcome measure was the reduction of the annualised relapse rate (ARR), and the secondary outcome measures were alteration of disability measured by expanded disability status scale (EDSS) score, the time to onset of the first relapse, and the progression of neuroradiological lesions at 1 year of treatment. Results At 1 year of treatment, the ARR dropped from 1.82 to 0.37 (p<0.0001). The mean EDSS score improved by 1.3 points, going from 5.8 at baseline to 4.5 at 1 year (p<0.0001). The number of patients showing gadolinium (Gad)+ spinal cord lesions at baseline, that is, 46.9%, dropped to 10.6% (a 77.4% reduction; p=0.02). The median time to onset of the first relapse was 18 months. IgG-NMO seropositivity was a predictive factor of relapse (p=0.006). A case of acute myeloid leukaemia was observed after a mean time span of 4.8 years. Conclusions In this observational NMO study, MTX decreased dramatically the frequency of relapses, which is directly related to progression of disability or even death in this disorder.
Approximate String Joins with Abbreviations

String joins have wide applications in data integration and cleaning. The inconsistency of data caused by data errors, term variations and missing values has led to the need for approximate string joins (ASJ). In this paper, we study ASJ with abbreviations, which are a frequent type of term variation. Although prior works have studied ASJ given a user-inputted dictionary of synonym rules, they have three common limitations. First, they suffer from low precision in the presence of abbreviations having multiple full forms. Second, their join algorithms are not scalable due to the exponential time complexity. Third, the dictionary may not exist since abbreviations are highly domain-dependent.We propose an end-to-end workflow to address these limitations. There are three main components in the workflow: (1) a new similarity measure taking abbreviations into account that can handle abbreviations having multiple full forms, (2) an efficient join algorithm following the filter-verification framework and (3) an unsupervised approach to learn a dictionary of abbreviation rules from input strings. We evaluate our workflow on four real-world datasets and show that our workflow outputs accurate join results, scales well as input size grows and greatly outperforms state-of-the-art approaches in both accuracy and efficiency.
Distribution of CD4pos -, CD8pos – and Regulatory T Cells in the Upper and Lower Gastrointestinal Tract in Healthy Young Subjects

The gastrointestinal immune system is involved in the development of several autoimmune-mediated diseases, including inflammatory bowel disease, multiple sclerosis, and type 1 diabetes mellitus. Alterations in T-cell populations, especially regulatory T cells (Tregs), are often evident in patients suffering from these diseases. To be able to detect changes in T-cell populations in diseased tissue, it is crucial to investigate T-cell populations in healthy individuals, and to characterize their variation among different regions of the gastrointestinal (GI) tract. While limited data exist, quantitative data on biopsies systematically drawn from various regions of the GI tract are lacking, particularly in healthy young humans. In this report, we present the first systematic assessment of how T cells—including Tregs—are distributed in the gastrointestinal mucosa throughout the GI tract of healthy young humans by means of multi-parameter FACS analysis. Gastroduodenoscopy and colonoscopy were performed on 16 healthy volunteers aged between 18 and 32. Biopsies were drawn from seven GI regions, and were used to determine the frequencies of CD8+-, CD4+- and Tregs in the gastrointestinal mucosa by means of multi-parameter FACS analysis. Our data show that there is significant variation in the baseline T-cell landscape along the healthy human gastrointestinal tract, and that mucosal T-cell analyses from a single region should not be taken as representative of the entire gastrointestinal tract. We show that certain T-cell subsets in the gastrointestinal mucosa vary significantly among regions; most notably, that Tregs are enriched in the appendiceal orifice region and the ascending colon, and that CD8pos T cells are enriched in the gastric mucosa.
The study on relationship among self- control and performance of family with social adaptation in high school students at Abadeh City

Abstract. Subject and objective : Adaptation is deemed as one of the human’s helpful and efficient behaviors in adjustment to physical and psychological environment in such a way that it is not only adapted to the environment and sufficed with following the environment unconsciously, but also it may affect on the environment and alter it appropriately. Hence, the present research was conducted in order to explore the relationship among self- control behavior and performance of family with high school students’ adaptation in Abadeh City (Fars Province, Iran). Methodology : This study was carried out as a cross- sectional- correlation research on 350 cohort students in terms gender, order of birth, and education. Tangney’s (2004) Brief Self- Control Scale (BSCS) questionnaire, Family Assessment Device (FAD), and Adjustment Inventory for School Students (AISS) were employed for data collection. Data were analyzed via SPSS (v.19) software and by means of independent T-Test, Pearson’s correlation coefficient and regression analysis. Findings : The current study includes both female (54.1%) and male (45.9%) students. The observation of mean rate of adolescents’ perception from family’s performances indicates that no remarkable difference may be seen in terms of dimensions of family’s performance between female and male adolescents while variables of self-control and social adaptation vary among females and males. Likewise, the results showed that the female students enjoy higher level of social adaptation than male students (P<0.05). Analysis of data indicated that there was significant relationship among variables of self- control and social adaptation between students so that the self- control might predict 21.7% of variance of social adaptation in students (p<0.05). Performance of family interpreted 11.4% of variance of social adaptation among students in the studied population. Similarly, the findings indicated that there was statistical significant correlation among higher adaptation of students in terms of variables of problem-solving, affective involvement, and behavior control at scale of family’s performance (P<0.001 & P<0.05). Conclusion : As the smallest social unit, family is assumed as the basis to form the community and protect from human’s emotions so with respect to its role in prediction of children’s adaptation, any deficiency and failure in family’s performance may adversely affect on normalization of behavior among children. Similarly, with respect to importance of role of self- controlling skills in experiencing psychological moods and prediction of social maladaptive behaviors, the necessity for addressing these factors may be felt further in social adaptation among students more than ever.
Stimulus‐dependent augmented gamma oscillatory activity between the functionally connected cortical neurons in the primary visual cortex

Neuronal assemblies typically synchronise within the gamma oscillatory band (30–80 Hz) and are fundamental to information processing. Despite numerous investigations, the exact mechanisms and origins of gamma oscillations are yet to be known. Here, through multiunit recordings in the primary visual cortex of cats, we show that the strength of gamma power (20–40 and 60–80 Hz) is significantly stronger between the functionally connected units than between the unconnected units within an assembly. Furthermore, there is increased frequency coherence in the gamma band between the connected units than between the unconnected units. Finally, the higher gamma rhythms (60–80 Hz) are mostly linked to the fast‐spiking neurons. These results led us to postulate that gamma oscillations are intrinsically generated between the connected units within cell assemblies (microcircuits) in relation to the stimulus within an emergent ‘50‐ms temporal window of opportunity’.
Architecture support for disciplined approximate programming

Disciplined approximate programming lets programmers declare which parts of a program can be computed approximately and consequently at a lower energy cost. The compiler proves statically that all approximate computation is properly isolated from precise computation. The hardware is then free to selectively apply approximate storage and approximate computation with no need to perform dynamic correctness checks. In this paper, we propose an efficient mapping of disciplined approximate programming onto hardware. We describe an ISA extension that provides approximate operations and storage, which give the hardware freedom to save energy at the cost of accuracy. We then propose Truffle, a microarchitecture design that efficiently supports the ISA extensions. The basis of our design is dual-voltage operation, with a high voltage for precise operations and a low voltage for approximate operations. The key aspect of the microarchitecture is its dependence on the instruction stream to determine when to use the low voltage. We evaluate the power savings potential of in-order and out-of-order Truffle configurations and explore the resulting quality of service degradation. We evaluate several applications and demonstrate energy savings up to 43%.
Axillary recurrence rate in breast cancer patients with negative sentinel lymph node.

AIM To assess the axillary recurrence rate in operable breast cancer patients with clinically negative axilla after negative sentinel lymph node in whom axillary lymph node dissection had not been performed. METHODS Fifty consecutive female operable breast cancer patients with negative sentinel lymph node biopsy in whom axillary lymph node dissection had not been performed were included in the study and prospectively followed, with median follow-up time of 32 months (range 10-50 months). Sentinel lymph node biopsy was performed by the triple method. RESULTS The sentinel node identification rate was 100%. In only one of 50 patients with negative sentinel lymph node, axillary recurrence developed 26 months after surgery. This was the sole patient with sentinel lymph node biopsy after previous surgical biopsy. After treatment, all patients were alive and with no evidence of disease. CONCLUSIONS Omitting axillary node dissection after negative sentinel node biopsy in operable breast cancer patients proved to be safe. Patients with previous open surgical biopsy should be given special attention in the follow-up.

Elderly patients with unexplained syncope: what should be considered a positive tilt test response?

INTRODUCTION Syncope is a common problem and can lead to serious consequences in the elderly. Tilt test is useful to investigate recurrent syncope, but few studies have investigated the hemodynamic responses of this population to tilt test. OBJECTIVE To describe the tilt test responses of elderly patients with recurrent syncope of unknown origin and to determine the occurrence of altered cardiovascular autonomic function in a subset of those with the diagnosis of dysautonomic pattern to the tilt test. METHODS Elderly patients (n=165; >60 years old) who sought medical assistance because of recurrent syncope during 18 months were initially enrolled and submitted to a two-stage, nitroglycerin-potentiated tilt test. A subset of patients who presented with dysautonomic response to tilt test performed clinical autonomic tests. RESULTS The most frequent cause of syncope during tilt test was the dysautonomic pattern (43%), followed by mixed type neurocardiogenic syncope (35%). Most patients who remained asymptomatic during tilt test showed clear abnormal hemodynamic response during the exam. CONCLUSION Autonomic dysfunction, which can be found during tilt test, is probably an important cause of syncope in the elderly, regardless of the occurrence of symptoms during the tilt test.
Electrical resistivity of ferromagnetic nickel and iron based alloys

The theoretical basis for the two-band model with spin-mixing which has been widely applied to the analysis of the transport properties of ferromagnetic metals is discussed in detail. This model is shown to have much more general validity than the original presentation suggested. The model is then applied to resistivity data in Ni and Fe based alloys to obtain a consistent set of parameters for the scattering within each spin band for various impurities, together with temperature dependent pure metal scattering rates.
Coriolis effects on wind turbine wakes across atmospheric boundary layer regimes

Wind turbines operate in the atmospheric boundary layer (ABL), where Coriolis effects are present. As wind turbines with larger rotor diameters are deployed, the wake structures that they create in the ABL also increase in length. Contemporary utility-scale wind turbines operate at rotor diameter-based Rossby numbers, the nondimensional ratio between inertial and Coriolis forces, of O(100) where Coriolis effects become increasingly relevant. Coriolis forces provide a direct forcing on the wake, but also affect the ABL base flow, which indirectly influences wake evolution. These effects may constructively or destructively interfere because both the magnitude and sign of the direct and indirect Coriolis effects depend on the Rossby number, turbulence, and buoyancy effects in the ABL. Using large eddy simulations, we investigate wake evolution over a wide range of Rossby numbers relevant to offshore wind turbines. Through an analysis of the streamwise and lateral momentum budgets, we show that Coriolis effects have a small impact on the wake recovery rate, but Coriolis effects induce significant wake deflections which can be parsed into two regimes. For high Rossby numbers (weak Coriolis forcing), wakes deflect clockwise in the northern hemisphere. By contrast, for low Rossby numbers (strong Coriolis forcing), wakes deflect anti-clockwise. Decreasing the Rossby number results in increasingly anti-clockwise wake deflections. The transition point between clockwise and anti-clockwise deflection depends on the direct Coriolis forcing, pressure gradients, and turbulent fluxes in the wake. At a Rossby number of 125, Coriolis deflections are comparable to wake deflections induced by 17{\deg} of yaw-misalignment.
Police Perceptions of Interviews Involving Children with Intellectual Disabilities: A Qualitative Inquiry

This study employed a qualitative method to explore the experiences of 20 police officers when interviewing children with intellectual disabilities. Three main themes were interpreted as representing challenges to the officers when interviewing special‐needs children: police organizational culture, participants' perceptions of these children as interviewees, and prior information. Participants in this inquiry mentioned poor organizational priority within the police force for child abuse cases and children with intellectual disabilities, as well as inadequate support for interviewing skills development and maintenance. Participants also attempted to equalize these children by interviewing them in the same way as their mainstream peers. Finally, participants viewed interview preparation as influential in determining an interview's successful outcome, but recognized that preparedness could bias their interviewing techniques. Increased attention towards these issues will provide a basis for developing strategies to minimize such challenges and thus improve the quality of interviews with children with intellectual disabilities.
