What Advice Is Currently Given to Patients with Age-Related Macular Degeneration (AMD) by Eyecare Practitioners, and How Effective Is It at Bringing about a Change in Lifestyle? A Systematic Review

There is currently no treatment for early/intermediate Age-related Macular Degeneration (AMD) but Eye Care Professionals (ECPs) are recommended to advise patients about modifiable lifestyle factors, including dietary changes, that can slow disease progression. The aim of this review was to understand advice currently given to patients with AMD by ECPs and to evaluate evidence regarding patient compliance. A systematic review was conducted of literature published in electronic databases: CINAHL, MEDLINE, PsycINFO, PyscARTICLES, EMBASE, AMED. Methods followed PRISMA guidelines (PROSPERO registration number: CRD42020223724). Twenty-four reports were eligible for inclusion, 12 focused on ECP experience, 7 on patient experience, and 6 on impact of advice (one paper reported on the ECP and patient experience). Studies reported that a substantial proportion of patients did not recall receiving lifestyle modification advice from their ECP (57.95%, range 2–95% across patient based studies). Practitioners were most likely to provide advice about nutritional supplements (80%, range 67–93% across ECP studies), and least likely about smoking (44%, range 28–71% across ECP studies), however supplements advised did not always comply with evidence-based guidelines. The main reason for patients not following lifestyle advice was lack of provision by the ECP (54.5%, range 21–94% across studies on the impact of advice). The review highlighted a need for more studies to understand patient preferences for receiving advice and research on ECP perceived barriers to advice provision.
Locality-Aware Optimizations for Improving Remote Memory Latency in Multi-GPU Systems

With generational gains from transistor scaling, GPUs have been able to accelerate traditional computation-intensive workloads. But with the obsolescence of Moore's Law, single GPU systems are no longer able to satisfy the computational and memory requirements of emerging workloads. To remedy this, prior works have proposed tightly-coupled multi-GPU systems. However, multi-GPU systems are hampered from efficiently utilizing their compute resources due to the Non-Uniform Memory Access (NUMA) bottleneck. In this paper, we propose DualOpt, a lightweight hardware-only solution that reduces the remote memory access latency by delivering optimizations catered to a workload's locality profile. DualOpt uses the spatio-temporal locality of remote memory accesses as a metric to classify workloads as cache insensitive and cache-friendly. Cache insensitive workloads exhibit low spatio-temporal locality, while cache-friendly workloads have ample locality that is not exploited well by the conventional cache subsystem of the GPU. For cache insensitive workloads, DualOpt proposes a fine-granularity transfer of remote data instead of the conventional cache line transfer. These remote data are then coalesced so as to efficiently utilize inter-GPU bandwidth. For cache-friendly workloads, DualOpt adds a remote-only cache that can exploit locality in remote accesses. Finally, a decision engine automatically identifies the class of workload and delivers the corresponding optimization, which improves overall performance by 2.5× on a 4-GPU system, with a small hardware overhead of 0.032%.
Algebra, selections, and additive Ramsey theory

Hindman's celebrated Finite Sums Theorem, and its high-dimensional version due to Milliken and Taylor, are extended from covers of countable sets to covers of arbitrary topological spaces with Menger's classic covering property. The methods include, in addition to Hurewicz's game theoretic characterization of Menger's property, extensions of the classic idempotent theory in the Stone--Czech compactification of semigroups, and of the more recent theory of selection principles. This provides strong versions of the mentioned celebrated theorems, where the monochromatic substructures are large, beyond infinitude, in an analytic sense. Reducing the main theorems to the purely combinatorial setting, we obtain nontrivial consequences concerning uncountable cardinal characteristics of the continuum. The main results, modulo technical refinements, are of the following type (definitions provided in the main text): Let $X$ be a Menger space, and $\mathcal{U}$ be an infinite open cover of $X$. Consider the complete graph, whose vertices are the open sets in $X$. For each finite coloring of the vertices and edges of this graph, there are disjoint finite subsets $\mathcal{F}_1,\mathcal{F}_2,\dots$ of the cover $\mathcal{U}$ whose unions $V_1 := \bigcup\mathcal{F}_1, V_2 := \bigcup\mathcal{F}_2,\dots$ have the following properties: 1. The sets $\bigcup_{n\in F}V_n$ and $\bigcup_{n\in H}V_n$ are distinct for all nonempty finite sets $F<H$. 2. All vertices $\bigcup_{n\in F}V_n$, for nonempty finite sets $F$, are of the same color. 3. All edges $\bigl\{\,\bigcup_{n\in F}V_n, \bigcup_{n\in H}V_n\,\bigr\}$, for nonempty finite sets $F<H$, have the same color. 4. The family $\{V_1,V_2,\dots\}$ is an open cover of $X$. A self-contained introduction to the necessary parts of the needed theories is provided.
Singular semipositive metrics in non-Archimedean geometry

Let X be a smooth projective Berkovich space over a complete discrete valuation field K of residue characteristic zero, endowed with an ample line bundle L. We introduce a general notion of (possibly singular) semipositive (or plurisubharmonic) metrics on L, and prove the analogue of the following two basic results in the complex case: the set of semipositive metrics is compact modulo constants, and each semipositive metric is a decreasing limit of smooth semipositive ones. In particular, for continuous metrics our definition agrees with the one by S. -W. Zhang. The proofs use multiplier ideals and the construction of suitable models of X over the valuation ring of K, using toroidal techniques.
Compression-induced failure of electroactive polymeric thin films

The onset of compression induces wrinkling in actuation devices based on electroactive polymer thin films, which leads to a sudden decrease in performances and, eventually, to failure. Inspired by the classical tension field theory for thin membranes, we provide a general framework for the analysis of the insurgence of in-plane compressions. Our main result is the analytical deduction of a voltage-dependent domain of tensile configurations in the principal stretches plane.
Homoclinic points, atoral polynomials, and periodic points of algebraic $\mathbb {Z}^d$-actions

Abstract Cyclic algebraic ${\mathbb {Z}^{d}}$-actions are defined by ideals of Laurent polynomials in $d$ commuting variables. Such an action is expansive precisely when the complex variety of the ideal is disjoint from the multiplicative $d$-torus. For such expansive actions it is known that the limit of the growth rate of periodic points exists and is equal to the entropy of the action. In an earlier paper the authors extended this result to ideals whose variety intersects the $d$-torus in a finite set. Here we further extend it to the case where the dimension of intersection of the variety with the $d$-torus is at most $d-2$. The main tool is the construction of homoclinic points which decay rapidly enough to be summable.
Thin-Film-Based Multifunctional System for Optical Detection and Thermal Treatment of Biological Samples

In this work, we present a multifunctional Lab-on-Chip (LoC) platform based on hydrogenated amorphous silicon sensors suitable for a wide range of application in the fields of biochemical and food quality control analysis. The proposed system includes a LoC fabricated on a 5 cm × 5 cm glass substrate and a set of electronic boards for controlling the LoC functionalities. The presented Lab-on-Chip comprises light and temperature sensors, a thin film resistor acting as a heating source, and an optional thin film interferential filter suitable for fluorescence analysis. The developed electronics allows to control the thin film heater, a light source for fluorescence and absorption measurements, and the photosensors to acquire luminescent signals. All these modules are enclosed in a black metal box ensuring the portability of the whole platform. System performances have been evaluated in terms of sensor optical performances and thermal control achievements. For optical sensors, we have found a minimum number of detectable photons of 8 × 104 s−1·cm−2 at room temperature, 1.6 × 106 s−1·cm−2 in presence of fluorescence excitation source, and 2.4 × 106 s−1·cm−2 at 90 °C. From a thermal management point of view, we have obtained heating and cooling rates both equal to 2.2 °C/s, and a temperature sensor sensitivity of about 3 mV/°C even in presence of light. The achieved performances demonstrate the possibility to simultaneously use all integrated sensors and actuators, making promising the presented platform for a wide range of application fields.
Cohomology for small categories: $k$ -graphs and groupoids

Given a higher-rank graph $\Lambda$, we investigate the relationship between the cohomology of $\Lambda$ and the cohomology of the associated groupoid $G_\Lambda$. We define an exact functor between the abelian category of right modules over a higher-rank graph $\Lambda$ and the category of $G_\Lambda$-sheaves, where $G_\Lambda$ is the path groupoid of $\Lambda$. We use this functor to construct compatible homomorphisms from both the cohomology of $\Lambda$ with coefficients in a right $\Lambda$-module, and the continuous cocycle cohomology of $G_\Lambda$ with values in the corresponding $G_\Lambda$-sheaf, into the sheaf cohomology of $G_\Lambda$.
Convergence groups and semiconjugacy

We study a problem that arises from the study of Lorentz surfaces and Anosov flows. For a non-decreasing map of degree one $h:\mathbb{S}^{1}\rightarrow \mathbb{S}^{1}$, we are interested in groups of circle diffeomorphisms that act on the complement of the graph of $h$ in $\mathbb{S}^{1}\times \mathbb{S}^{1}$ by preserving a volume form. We show that such groups are semiconjugate to subgroups of $\text{PSL}(2,\mathbb{R})$ and that, when $h\in \text{Homeo}(\mathbb{S}^{1})$, we have a topological conjugacy. We also construct examples where $h$ is not continuous, for which there is no such conjugacy.
Khovanov homology is a skew Howe 2-representation of categorified quantum sl(m)

We show that Khovanov homology (and its sl(3) variant) can be understood in the context of higher representation theory. Specifically, we show that the combinatorially defined foam constructions of these theories arise as a family of 2-representations of categorified quantum sl(m) via categorical skew Howe duality. Utilizing Cautis-Rozansky categorified clasps we also obtain a unified construction of foam-based categorifications of Jones-Wenzl projectors and their sl(3) analogs purely from the higher representation theory of categorified quantum groups. In the sl(2) case, this work reveals the importance of a modified class of foams introduced by Christian Blanchet which in turn suggest a similar modified version of the sl(3) foam category introduced here.
Fast Hyperspectral Image Dehazing With Dark-Object Subtraction Model

Haze in hyperspectral images (HSIs) is a common phenomenon, which severely degrades the quality of the acquired data and limits its applications. In this letter, a dark-object subtraction model is proposed for haze removal of HSIs, which mainly is composed of three steps. First, a haze density map is estimated according to the haze characteristic in different spectral channels. Then, we design a saliency measure method to automatically calculate the haze abundance of different channels. Finally, the haze-free image is obtained by solving the dark-object subtraction model. Experiments on real and simulated datasets demonstrate that our method consistently outperforms other state-of-the-art dehazing techniques in terms of reconstructed performance and computational cost.
Comparison of compressive imaging and video techniques for threat detection applications

High performance imaging sensors are a fundamental requirement for many defense and security applications. The usually high cost of such sensors, however, prevents their broad deployment. Modern Computational Imaging approaches like Compressed Sensing (CS) promise cost efficient sensor architectures that might enable a wider usage of some sensor technologies. However, the technological potential for military applications still has to be verified. In order to test the capabilities of a CS-system for threat detection, a software framework for automated testing was implemented. The code contains different methods for scene modulation and image reconstruction. In our previous work, we studied the classic iterative optimization methods for image reconstruction with promising, but not completely satisfactory results. Therefore, we implemented another method. This CS video method is the ‘Fourier domain regularized inversion’ (FDRI) which promises real time single pixel video imaging. In the study presented here, we compare the rather new method with the already implemented optimization approaches regarding runtime, conventional image quality metrics and suitability for threat detection applications in different spectral bands.
The use of different methods of celiac plexus neurolysis in the treatment of pain syndrome associated with pancreatic cancer

Черевне сплетення є визнаною мішенню для інтервенційних методик лікування болю, що виникає внаслідок неоперабельного злоякісного новоутворення підшлункової залози або інших органів, розташованих у верхній половині черевної порожнини. Представлено клінічний випадок пацієнтки, 66 років, з раком підшлункової залози, якій для зменшення больового синдрому здійснено декілька спроб застосувати методики нейролізису сонячного сплетення. У зв’язку з великим розміром пухлини та її проростанням у навколишні органи провести симпатолізис під час біопсії за допомогою ендоскопічної ультрасонографії було неможливо. Спроба нейролізису переднім трансабдомінальним доступом під ультразвуковою навігацією не дала бажаного результату. Задній крізьшкірно-паравертебральний підхід під комп’ютерно-томографічним контролем сприяв значному полегшенню стану пацієнтки. Проведено порівняння різних методик нейролізису сонячного сплетення, їхніх переваг та недоліків використання в закладах охорони здоров’я України. The celiac plexus is a recognized target for interventions to provide pain relief to patients with pain resulting from inoperable malignancies of the pancreas or other organs in the upper abdomen.The clinical case of a 66-year-old female patient with pancreatic cancer who underwent several different techniques of celiac plexus neurolysis to reduce pain is presented. Due to the large size of the tumor and its extension into adjacent organs, it was not possible to perform sympatholysis during the biopsy using endoscopic ultrasonography. An attempt of neurolysis through an anterior transabdominal US-guided approach did not bring the desired result. Posterior percutaneous paravertebral CT-guided approach provided a significant relief of the patient's condition.Comparisons of different methods of the celiac plexus neurolysis and their advantages and disadvantages of use in health care institutions of Ukraine are given.If it is impossible to perform neurolysis with the help of endosonography, anterior transabdominal US-guided approach, or if there are difficulties in performing them, we recommend performing neurolysis by posterior percutaneous-paravertebral CT-guided approach.
Endoscopic Full Thickness Resection compared to Submucosal Tunnel Endoscopic Resection for Treatment of Gastric Gastrointestinal Stromal Tumor

Introduction Submucosal tunnel endoscopic resections (STER) had been increasingly performed for treatment of gastric GIST, while STER was limited by close dissection within tunnel and risking breach of tumor capsule. Endoscopic full thickness resection (EFTR) allowed resection of GIST with margins to prevent recurrence. This study aimed to compare EFTR against STER for treatment of gastric GIST. Method We retrospectively reviewed clinical outcomes of patients with gastric GIST who received either STER or EFTR. Gastric GIST less than 4cm were recruited. The clinical outcomes including baseline demographics, perioperative and oncological outcomes were compared between two groups. Results From 2013 to 2019, 46 patients with gastric GIST were treated by endoscopic resection, 26 received EFTR and 20 received STER. Most of the GISTs were in proximal stomach. There was no difference in operative time (94.9 vs 84.9 mins; p = 0.401), while endoscopic suturing was applied more for closure after EFTR (p < 0.0001). Patients after STER had earlier resumption of diet and shorter hospital stay while there was no difference in adverse event rate between two groups. The en-bloc resection rate for EFTR was significantly higher than STER (100% vs 80%; p = 0.029) while there was no difference in the local recurrence. Conclusion This study demonstrated that although patients who received EFTR had longer hospital stay and slower resumption of diet compared to STER, EFTR achieved significantly higher rate of en-bloc resection compared to STER for treatment of gastric GIST.
Developing A Moodle-Based Learning Management System (LMS) for Slow Learners

This study aimed to develop a Moodle-based Learning Management System (LMS) called eLSIDA (e-Learning STKIP PGRI Sidoarjo Asistif), which is validly used by students slow to study at STKIP PGRI Sidoarjo. This study used 3 out of 5 ADDIE models, namely Analysis, Design, and Development. Expert judgment in this study consists of two experts, material experts, and media experts. The research instrument used to obtain research data is a questionnaire. The data that has been obtained is then analyzed using descriptive analysis. Validation results from material experts obtained a score of 92.5%, while the results of media expert validation obtained a score of 95%. Based on the expert judgment assessment shown that eLSIDA that has been developed in general can be declared valid and worth to be used. The media that has been developed can be accessed through http://lms.elsida. ac.id/Although the development of eLSIDA has been considered valid, the effectiveness of the media on eLSIDA needs to be tested further.
The Alternative Form of Fermat's Equation

An alternative form of Fermats equation[1] is proposed. It represents a portion of the identity that includes three terms of Fermats original equation. This alternative form permits an elementary and compact proof of the first case of Fermats Theorem (FT) for a number of specific exponents. Proofs are given for exponents n equal to 3, 5, 7,11 and 13. All these cases have already been proven using the original Fermats equation, not to mention the fact that a complete proof of FT was given by A. Wiles [2]. In view of this, the results presented here carry a purely methodological interest. They illustrate the effectiveness and simplicity of the method,compared with the well-known classical approach. An alternative form of the equation permits use of the criterion of the incompatibility of its terms, avoiding the labor-intensive and sophisticated calculations associated with traditional approach.
Higher Massey products in the cohomology of mild pro-p-groups

Translating results due to J. Labute into group cohomological language, A. Schmidt proved that a finitely presented pro-p-group G is mild and hence of cohomological dimension cd G = 2 if H1(G,Fp) = U⊕V as Fpvector space and the cup-productH(G, Fp)⊗H 1(G,Fp) → H 2(G,Fp) maps U ⊗ V surjectively onto H2(G,Fp) and is identically zero on V ⊗ V . This has led to important results in the study of p-extensions of number fields with restricted ramification, in particular in the case of tame ramification. In this paper, we extend Labute’s theory of mild pro-p-groups with respect to weighted Zassenhaus filtrations and prove a generalization of the above result for higher Massey products which allows to construct mild pro-pgroups with defining relations of arbitrary degree. We apply these results for one-relator pro-p-groups and obtain some new evidence of an open question due to Serre. 1. Statement of results The central objects studied in this paper are mild pro-p-groups whose concept is due to J. Labute. By definition mild pro-p-groups admit a presentation in terms of generators and relators, where the relators satisfy a condition of being free in a maximal possible way with respect to suitably chosen filtrations. Mild pro-p-groups are of cohomological dimension 2 which is one of the main reasons for their importance also from an arithmetic point of view. In [14], using the theory of mild pro-p-groups, J. Labute gave the first examples of groups of the form GS(p) = Gal(QS(p)|Q) satisfying cd GS(p) = 2 in the tame case, i.e. where p 6∈ S. Here p is an odd prime number and QS(p) denotes the maximal pro-p-extension of Q unramified outside S. This has led to further extensive contributions in more general situations including arbitrary number fields and the case p = 2. A. Schmidt showed that over a number field the sets S of primes satisfying cd GS(p) = 2 are cofinal among all finite sets of primes even in the tame case (cf. [21], Th. 1.1). These arithmetic results require efficient methods to decide when a given pro-p-group is mild. Such a criterion is given by the following Date: May 5, 2014. 2010 Mathematics Subject Classification. 12G10, 20F05, 20F40, 22D15, 55S30. key words and phrases.

Group actions, the Mattila integral and applications

The Mattila integral, $$ {\mathcal M}(\mu)=\int {\left( \int_{S^{d-1}} {|\widehat{\mu}(r \omega)|}^2 d\omega \right)}^2 r^{d-1} dr,$$ developed by Mattila, is the main tool in the study of the Falconer distance problem. In this paper, with a very simple argument, we develop a generalized version of the Mattila integral. Our first application is to consider the product of distances $$(\Delta(E))^k= \left\{\prod_{j=1}^k |x^j-y^j|: x^j, y^j\in E\right\} $$ and show that when $d\geq 2$, $(\Delta(E))^k$ has positive Lebesgue measure if $\dim_{\mathcal{H}}(E)>\frac{d}{2}+\frac{1}{4k-1}$. Another application is, we prove for any $E,F,H\subset\mathbb{R}^2$, $\dim_{\mathcal{H}}(E)+\dim_{\mathcal{H}}(F)+\dim_{\mathcal{H}}(H)>4$, the set $$E\cdot(F+H)=\{x\cdot(y+z): x\in E, y\in F, z\in H\}$$ has positive Lebesgue.
QoS-Aware Multipath Routing in Software-Defined Networks

The emergence of new applications, such as online gaming and virtual reality, necessitates the underlying network capable of fulfilling high bandwidth and low latency requirements. The software-defined multipath routing is a viable approach to fulfill such quality-of-service (QoS) requirements by improving the data delivery performance through multipath. In this paper, we propose a QoS-aware dynamic multipath routing scheme for enhancing QoS of high-bandwidth applications in an SDN-enabled network. The proposed scheme consists of three phases – flow splitting, multipath routing, and flow reordering. In the first phase, we propose a flow splitting scheme to decide how to split the incoming flows to enable multipath routing in the network. In the second phase, we design a cost function for routing the splittable subflows and formulate a min-cost routing problem as an integer linear program (ILP). To solve the problem in polynomial time, we propose a greedy heuristic approach. Finally, in the third phase, we propose a flow reordering scheme for the received subflows through multiple paths to maintain the desired flow sequence at the destination. The experimental results show that the proposed scheme achieves higher network throughput by 22% compared to the benchmark schemes. Further, the proposed scheme achieves a reduction in QoS violated flows by 24% compared to the benchmark schemes.
