ON SOLUTIONS TO NONHOMOGENEOUS ALGEBRAIC DIFFERENTIAL EQUATIONS AND THEIR APPLICATION

AbstractWe consider solutions to the algebraic differential equation $\def \xmlpi #1{}\def \mathsfbi #1{\boldsymbol {\mathsf {#1}}}\let \le =\leqslant \let \leq =\leqslant \let \ge =\geqslant \let \geq =\geqslant \def \Pr {\mathit {Pr}}\def \Fr {\mathit {Fr}}\def \Rey {\mathit {Re}}f^nf'+Q_d(z,f)=u(z)e^{v(z)}$, where $Q_d(z,f)$ is a differential polynomial in $f$ of degree $d$ with rational function coefficients, $u$ is a nonzero rational function and $v$ is a nonconstant polynomial. In this paper, we prove that if $n\ge d+1$ and if it admits a meromorphic solution $f$ with finitely many poles, then $$\begin{equation*} f(z)=s(z)e^{v(z)/(n+1)} \quad \mbox {and}\quad Q_d(z,f)\equiv 0. \end{equation*}$$ With this in hand, we also prove that if $f$ is a transcendental entire function, then $f'p_k(f)+q_m(f)$ assumes every complex number $\alpha $, with one possible exception, infinitely many times, where $p_k(f), q_m(f)$ are polynomials in $f$ with degrees $k$ and $m$ with $k\ge m+1$. This result generalizes a theorem originating from Hayman [‘Picard values of meromorphic functions and their derivatives’, Ann. of Math. (2)70(2) (1959), 9–42].

DEPENDENCE OF THE OUTER DENSITY PROFILES OF HALOS ON THEIR MASS ACCRETION RATE

We carry out a systematic exploration of the effect of pre-impact rotation on the outcomes of low-speed collisions between planetesimals modeled as gravitational aggregates. We use pkdgrav, a cosmology code adapted to collisional problems and recently enhanced with a new soft-sphere collision algorithm that includes more realistic contact forces. A rotating body has lower effective surface gravity than a non-rotating one and therefore might suffer more mass loss as the result of a collision. What is less well understood, however, is whether rotation systematically increases mass loss on average regardless of the impact trajectory. This has important implications for the efficiency of planet formation via planetesimal growth, and also more generally for the determination of the impact energy threshold for catastrophic disruption (leading to the largest remnant retaining 50% of the original mass), as this has generally only been evaluated for non-spinning bodies. We find that for most collision scenarios, rotation lowers the threshold energy for catastrophic dispersal. For head-on collisions, we develop a semi-analytic description of the change in the threshold description as a function of the target's pre-impact rotation rate, and find that these results are consistent with the "universal law" of catastrophic disruption developed by Leinhardt & Stewart. Using this approach, we introduce re-scaled catastrophic disruption variables that take into account the interacting mass fraction of the target and the projectile in order to translate oblique impacts into equivalent head-on collisions.

RALP is more expensive than ORP, but it is not clear whether subsequent postoperative costs vary. We assessed the economic impact of RALP and ORP on patients and their families in the year following surgery. METHODS We recruited ORP and RALP patients planning surgery for stage T1-T2 prostate cancer at an academic cancer center. Economic impact questionnaires were completed at 3, 6, and 12 months after surgery. The self-administered survey included items regarding the use and cost of health services and supplies, health insurance coverage and employment, and changes in the patient’s and his family’s finances since prostate cancer surgery. RESULTS Between June 2010 and September 2013, 441 of 584 eligible patients consented (76% response rate), and 205 completed a 12-month assessment, of whom 39% had ORP and 61% had RALP. All patients had health insurance. Of 179 men (87%) who reported any new prescription medications since surgery, 12% said insurance did not cover any of the cost of those medications. Of 173 men (84%) who reported new use of incontinence pads, 75% had no insurance coverage for those costs and 23% were uncertain. Of 159 men who were working full- or part-time before surgery, 6% did not return to work after prostatectomy, 36% missed more than 4 weeks of work and 19% had no paid sick days. Approximately 22% of men said their monthly income was lower and 45% said their monthly expenses were greater than before surgery. Almost 88% of men said that since surgery they spent money on hospital, physician or other provider bills, medications, supplies or alternative therapies. About 37% said that since surgery they or their families had to downscale their lifestyle, not pay bills or pay them late, or use money from savings. Nearly 21% of men reported visiting an emergency department at least once in the 12 months following prostatectomy. Comparing men who had RALP vs. ORP, there were no statistically significant differences in their reports of new prescriptions, pad use, return to work, use of sick days, or other postoperative expenses or health care utilization. CONCLUSIONS Both RALP and ORP are associated with an economic burden on patients and their families, and many postoperative costs are not covered by health insurance. Neither approach appears to have an economic advantage from the patient perspective. © 2014FiguresReferencesRelatedDetails Volume 191Issue 4SApril 2014Page: e927-e928 Advertisement Copyright & Permissions© 2014MetricsAuthor Information Will Lowrance More articles by this author Coral Swartz More articles by this author James Eastham More articles by this author Elena Elkin More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...

Introduction: Currently measures of glycaemic variability (Standard Deviation, Mean and MAGE) all fail to fully highlight the extent of blood glucose variability so there is a need for improved measures of glycaemic variability. Aim: To utilise clinical data produced using CGMS to develop and validate a clinically-relevant novel measure of glycaemic variability and to use it to compare CSII with MDI. Methods: 20 participants (6 months pre and post CSII) with 24 hr CGM data sets were analysed. Glucose variability Rating (GVR) was calculated in three steps including change in sensor reading at 5 minute intervals which were then squared and av- eraged to obtain GVR (mmol/L) 2/hr. GVR was plotted, area under curve (AUC) calculated and pre vs. post-CSII GVR compared. Time series analysis was also investigated to try and identify specific periods with increased variability. A compari- son of the percentage change in GVR vs the change in HbA1c value in pre vs post-CSII was also analysed to identify correla- tion between these two measures. Results: GVR was applied to pre and post-CSII CGM data; 75% of participants showed < 20% reduction of GVR post-CSII vs. MDI. The group also showed a significant reduction in GVR (p < 0.003) post-CSII (vs MDI). Conclusions: Results indicate a reduction in glucose vari- ability with CSII and highlight the limitations of HbA1c, as well as the useful potential of GVR to highlight specific time periods where intervention is required to control blood glucose variability.

SYMPTOM CLUSTERS IN PATIENTS ON DIALYSIS AND THEIR ASSOCIATION WITH QUALITY‐OF‐LIFE OUTCOMES

Patients who are on dialysis report multiple symptoms. The aim of the study was to explore and identify symptom clusters (co-occurring symptoms) in patients on dialysis and their possible associations with depressive symptoms and health-related quality-of-life (HRQOL) outcomes. In a cross-sectional study of 301 prevalent patients on dialysis, physical symptoms, depressive symptoms and HRQOL were assessed using the Beck Depression Inventory (BDI) and the Kidney Disease and Quality-of-Life-Short Form version 1.3 (KDQOL-SF36) questionnaires. Symptom clusters were identified using principal component analysis with varimax rotation. Multivariate linear regression analyses were carried out to evaluate the relationships between symptom clusters and depressive symptoms and HRQOL outcomes. The majority of patients (63.5%) rated their symptoms in the 'very much' to 'extremely bothersome' range, and 29.4% had significant depressive symptoms. Three symptom clusters were identified and were named uraemic (nausea, lack of appetite, dizziness/faintness, feeling squeezed out, shortness of breath, chest pain), neuromuscular (numbness in extremities, sore muscles, cramps) and skin (itching, dry skin) clusters. The three clusters were associated with BDI, physical component summary (PCS) and mental component summary (MCS) scores. After multiple adjustments, the uraemic and neuromuscular clusters remained independently associated with BDI and PCS scores and the uraemic and skin clusters with MCS scores. The strong associations between symptom clusters and depressive symptoms and the physical and mental domains of HRQOL should lead to an increased focus on symptom-alleviating interventions. Additional research is warranted to determine whether treatment of symptom clusters rather than single symptoms will improve HRQOL.

ON SOME MODULAR EQUATIONS AND THEIR APPLICATIONS II

We first derive some modular equations of degrees 3 and 9 and present their concise proofs based on algebraic computations. We then use these modular equations to establish explicit relations and formulas for the parameterizations for the theta functions <TEX>${\varphi}$</TEX> and <TEX>${\psi}$</TEX> In addition, we find specific values of the parameterizations to evaluate some numerical values of the cubic continued fraction.

An insect-inspired bionic sensor for tactile localization and material classification with state-dependent modulation

Insects carry a pair of antennae on their head: multimodal sensory organs that serve a wide range of sensory-guided behaviors. During locomotion, antennae are involved in near-range orientation, for example in detecting, localizing, probing, and negotiating obstacles. Here we present a bionic, active tactile sensing system inspired by insect antennae. It comprises an actuated elastic rod equipped with a terminal acceleration sensor. The measurement principle is based on the analysis of damped harmonic oscillations registered upon contact with an object. The dominant frequency of the oscillation is extracted to determine the distance of the contact point along the probe and basal angular encoders allow tactile localization in a polar coordinate system. Finally, the damping behavior of the registered signal is exploited to determine the most likely material. The tactile sensor is tested in four approaches with increasing neural plausibility: first, we show that peak extraction from the Fourier spectrum is sufficient for tactile localization with position errors below 1%. Also, the damping property of the extracted frequency is used for material classification. Second, we show that the Fourier spectrum can be analysed by an Artificial Neural Network (ANN) which can be trained to decode contact distance and to classify contact materials. Thirdly, we show how efficiency can be improved by band-pass filtering the Fourier spectrum by application of non-negative matrix factorization. This reduces the input dimension by 95% while reducing classification performance by 8% only. Finally, we replace the FFT by an array of spiking neurons with gradually differing resonance properties, such that their spike rate is a function of the input frequency. We show that this network can be applied to detect tactile contact events of a wheeled robot, and how detrimental effects of robot velocity on antennal dynamics can be suppressed by state-dependent modulation of the input signals.

POPULATION DENSITY OF PHYTONOMUS VARIABILIS HRBST. AND PHYTODECTA FORNICATA BRUGG. ON MULTIFOLIOLATE AND TRIFOLIOLATE ALFALFA IN RELATION TO ANATOMICAL CHARACTERISTICS ON THEIR LEAVES

Two alfalfa cultivars - the multifoliolate “Mnogolistna 1” and the trifoliolate “Europe” were investigated for their resistance towards two main alfalfa defoliators Phytonomus variabilis Hrbst., 1795 and Phytodecta fornicata Brugg., 1873. The results of the two year study showed that the population density of both pests was higher in the“Mnogolistna 1” fields. The anatomical study of the leaves showed that multifoliolate alfalfa cultivar has narrower palisade and spongy parenchyma and thinner leaves and cuticle which make it less resistant to Ph. variabilis and Ph. fornicata.

COMPARATIVE STUDY OF RMA AND PFA ON THEIR RESPONSES TO MOVING TARGET

The synthetic aperture radar (SAR) signatures of moving target are the basis of ground moving target indication and imaging (GMTI&Im) in the framework of SAR systems. However, previous studies are mainly based on the 2-D separable SAR processing, and little work has been done to investigate the signatures of moving target after the application of a particular flne resolution SAR image formation algorithm. In this paper, we derive the image spectrum of moving target after two representative flne resolution SAR image formation algorithms, i.e., the range migration algorithm (RMA) and polar format algorithm (PFA), respectively. Based on the spectrum derived, detailed analysis on the SAR signatures of moving target, including the geometric displacement, residual range migration, and defocusing efiect in both the range and azimuth dimensions are performed. The presented work might be helpful when considering a SAR system with the capability of ground moving target indication and imaging (GMTI&Im).
