description: Основная идея статьи заключается в рассмотрении вопросов о том, какой тип гендерной системы сформировался в российской цивилизации, как он влияет на ее развитие и какие тенденции в области прав человека, протекающие в развитых цивилизациях, необходимо поддерживать в нашей стране. Дается краткий обзор современных теоретических подходов к определению термина цивилизация. Особое внимание уделяется рассмотрению концепций универсальной общечеловеческой цивилизации, выдвигаемых отечественными мыслителями. Автор отмечает, что признанная специфика российской цивилизации (византийское происхождение религии и принципов политической организации, подчинение человека общине и государству как духовный принцип, матрифокальность культурных традиций) сформировала российскую гендерную систему как патриархатную. На основе международных исследований показываются позитивные социальноэкономические и гуманитарные последствия использования политики гендерного равенства. В заключение описываются объективные тенденции к формированию общечеловеческой универсальной цивилизации, основанной в том числе и на принципе гендерного равенства.
Equivalence and nonequivalence of ensembles: Thermodynamic, macrostate, and measure levels

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We present general and rigorous results showing that the microcanonical and canonical ensembles are equivalent at all three levels of description considered in statistical mechanics - namely, thermodynamics, equilibrium macrostates, and microstate measures - whenever the microcanonical entropy is concave as a function of the energy density in the thermodynamic limit. This is proved for any classical many-particle systems for which thermodynamic functions and equilibrium macrostates exist and are defined via large deviation principles, generalizing many previous results obtained for specific classes of systems and observables. Similar results hold for other dual ensembles, such as the canonical and grand-canonical ensembles, in addition to path ensembles used for describing nonequilibrium systems driven in steady states.

description: В статье, анализируются формы проявления гражданского активизма деятелей культурнодосуговых учреждений, выявленное в ходе полевых исследований. В качестве метода социологического опроса было выбрано проведение глубинных интервью с представителями районной администрации, с деятелями культурно-досуговых учреждений, с жителями районных центров. В статье показано, что для районных и особенно сельских библиотек и музеев актуальна проблема низкой посещаемости. Задачу по привлечению посетителей удаётся решать, как правило, инициативным сотрудникам. Нами были выявлены несколько видов действий по привлечению внимания местных жителей к их учреждениям. Во-первых, многие сотрудники библиотек проводят встречи с писателями и поэтами, во-вторых, проводятся различные мероприятия. В-третьих, и в музеях, и в библиотеках проходят разнообразные выставки. В-четвёртых, деятели культуры проводят беседы и экскурсии, на различные темы, это могут быть патриотические сюжеты, экологические и многое другое. В ходе исследования было обнаружено, что формирование мировоззрения и поддержание культурного уровня местного сообщества держится только на энтузиазме педагогов и деятелей культурно-досуговых учреждений, которые остаются одними из главных носителей российской культуры в районных центрах.

description: Цель статьи - через анализ основных тенденций развития и выявление сущностных особенностей современного общества обозначить исторические перспективы человечества, назвать главные гуманитарные угрозы и риски. Утверждается, что в современном глобальном сетевом информационно-коммуникативном обществе создаются предпосылки для качественно нового уровня и масштаба воздействия, в том числе манипуляционного, на массовое и индивидуальное сознание. Делается вывод, что возможным способом преодоления возникающих гуманитарных угроз и рисков, обеспечения социальной устойчивости и безопасности является формирование такой модели социальной коммуникации, базовыми принципами которой станут рациональность, диалогичность, ориентированность на достижение взаимовыгодного соглашения. Указывается на то, что философское обоснование данной модели содержится в теории коммуникативного действия Ю. Хабермаса и теории систем Н. Лумана.
Three-dimensional iso-geometric solutions to general boundary value problems of Toupin's gradient elasticity theory at finite strains

description: We present, to the best of our knowledge, the first complete three-dimensional numerical solutions to a broad range of boundary value problems for a general theory of finite strain gradient elasticity. We have chosen for our work, Toupin's theory [Arch. Rat. Mech. Anal., 11(1), 385-414, 1962]-one of the more general formulations of strain gradient elasticity. Our framework has three crucial ingredients: The first is iso-geometric analysis [Hughes et al., Comp. Meth. App. Mech. Engrg., 194(39-41), 4135-4195, 2005], which we have adopted for its straightforward and robust representation of C1-continuity. The second is a weak treatment of the higher-order Dirichlet boundary conditions in the formulation, which control the development of strain gradients in the solution. The third ingredient is algorithmic (automatic) differentiation, which eliminates the need for linearization "by hand" of the rather complicated geometric and material nonlinearities in gradient elasticity at finite strains. We present a number of numerical solutions to demonstrate that the framework is applicable to arbitrary boundary value problems in three dimensions. We discuss size effects, the role of higher-order boundary conditions, and perhaps most importantly, the relevance of the framework to problems with elastic free energy density functions that are non-convex in strain space.

description: This document constitutes a report of the work performed within Task 2.2 “AI HLEG/AI4EU Ethics Guidelines Compliance Assurance, Data Protection and IPR”. Therefore, in correspondence with the objectives of this task, this Deliverable provides an analysis of the ethical and legal principles that AI systems and solutions within I-NERGY should follow as well as guidance for the handling of possible IPR issues.
 To assess these legal principles and provide guidance for compliance with the applicable legal frameworks, I-NERGY follows an approach which considers a) the applicable data protection frameworks b) the network and information security directive and c) some key energy domain regulations and standards. Some of these legal frameworks considered impose direct requirements for the solutions being developed within the project, while the others provide guidance for compliance for the future products and services.
 The approach to the ethical dimension of AI systems within I-NERGY aims to identify possible ethical issues that may arise focusing on energy domain, and to provide a set of recommendations to tackle these issues and strengthen the trustworthiness of the developed solutions, focusing mainly on the respective Ethics Guidelines developed by the High-Level Expert Group on AI.
 Concerning the IPR implications that may arise in terms of background and foreground, this document aims to provide guidance on how such issues are managed within the I-NERGY consortium.
LONG-TERM LOCAL DELIVERY OF GRISEOFULVIN FOR TREATMENT OF OCULAR NEOVASULARIZATION

description: Age-related macular degeneration (AMD) is one of the leading causes of irreversible vision loss and blindness in elderly population worldwide. Current AMD treatments based on anti-vascular endothelial growth factor therapy are ineffective in a significant fraction of patients. In the quest of alternative targets, ferrochelatase (FECH) was identified as a promising target. FECH is a metalloenzyme and can be inhibited by a known anti-fungal drug griseofulvin (GRF), a microtubule inhibitor. Long-term delivery to the posterior segment of the eye is critical to repurposing GRF for AMD therapy. A long-acting release GRF-eluting poly(lactic-co-glycolic acid) (PLGA) microparticles (MPs) system was developed for intravitreal administration. Particle size distribution (<20 µm), drug loading (>3.5 wt%), and drug release kinetics (>30 days) were identified as critical quality attributes (CQAs) of MP formulation. Magnesium hydroxide [Mg(OH)2] was encapsulated in MPs, varying the amount from 2 to 20 wt% of total mass, to control the release kinetics of GRF. Among the tested GRF MP formulations, the MP containing 2% Mg(OH)2 showed a minimal burst release (~18% of total loaded drug in 1 day) and continuous release (~100% in 38 days) and was considered optimal for 1 month delivery. GRF MPs provided sustained release of bioactive GRF and inhibited proliferation and tube formation of human retinal endothelial cells for a prolonged period compared to the unformulated GRF solution. In vivo efficacy of GRF MPs was evaluated in a mouse model of laser-induced choroidal neovascularization (L-CNV). The volume of neovascularization was estimated from in situ optical coherent tomography and confocal images of stained ex vivo choroids. GRF MPs provided a sustained effect in reducing CNV lesion volume. Fluorescein angiography suggests that GRF MPs reduce the severity of lesions. Also, in-situ imaging of fundus and ex-vivo microscopic imaging of retina suggest that GRF MPs do not cause off-target damage in the eyes and are safe for intravitreal administration. These results support that PLGA MPs can prolong the antiangiogenic effect of GRF and interfere with the progression of neovascularization in the eyes. Therefore, the GRF MP formulation may be further optimized for AMD therapy. Chapter 1 discusses the understanding of age-related macular degeneration, current therapy, and drug delivery approaches to the posterior segment of eyes. Chapter 2 discusses the goal of the research work. Chapter 3 describes the development and characterization of long-acting release formulation for intravitreal administration. Chapters 4 and 5 discuss evaluation of developed formulation in vitro in cell models and in vivo in animal models, respectively.

description: Der Begriff Solidarität wird im Alltag gerne bedenkenlos mit Migration und Flucht in Verbindung gebracht. Welche konkreten Beziehungen und Handlungsinhalte jedoch mit dem Begriff bezeichnet werden, ist nur schwach bestimmt. Der vorliegende Beitrag zeichnet daher zunächst die Begriffshistorie und daraus hervorgegangene widersprüchliche Bedeutungsdimensionen nach. Anschließend werden anhand von Beispielen des pro-migrantischen Aktivismus in Europa die Herausforderungen von Solidaritätsvarianten beleuchtet, die aus dem Impuls des Mitgefühls entstehen (‚Mitgefühlsolidarität‘). Daran wird deutlich, dass der Solidaritätsbegriff mitunter auf einer rein diskursiven Ebene oder als Form der Selbstbeschreibung eingesetzt wird, um gesellschaftliche Ideale zu formulieren. Gleichzeitig sind gerade im Migrations- und Fluchtkontext die konkreten, in den sozialen Nahraum eingelagerten solidarischen Praktiken von ökonomischen oder symbolischen Ungleichheiten zwischen den Gebenden und den Empfangenden von Unterstützungsleistungen gekennzeichnet. Obwohl eigentlich inkludierend gedacht, kann diese pro-migrantische Solidarität daher paternalistische und viktimisierende Dimensionen vor allem dann entfalten, wenn die soziale Distanz aufrechterhalten wird. In Konstellationen also, in denen keine neue Gemeinschaftsform angestrebt und die exkludierenden Dimensionen der eigenen Gesellschaft weder hinterfragt noch verändert werden, nützt der Solidaritätsbegriff letzten Endes der Aufrechterhaltung bestehender symbolischer Grenzen.

description: Не вызывает сомнений то, что иммигранты всегда влияли на американскую культуру. Но и образ иммигранта, нарисованный в американской культуре, очень сильно влиял на восприятие иммигрантов в американском обществе. По популярной музыке, литературе и кино легко проследить как американцы воспринимали иммигрантов: начиная с триумфа мюзикла «Плавильный котёл», где США прославляются как место спасения всех иммигрантов, через популярный кинообраз простоватого «Бродяги» Чарли Чаплина, затем резко негативный образ иммигранта в «Великом Гэтсби» к постепенному введению образа борца за американскую мечту в Голливудском кино 1930-1940 гг. В 1917 - 1965 гг., когда официально иммигрировать в США было очень сложно, иммигрантов видели через образы музыкантов, актеров и исполнителей. Одновременно иммигранты предвосхитили завершение периода сегрегации - в период «законов Джима Кроу» афроамериканский джаз стал массово популярен среди белых американцев благодаря белым музыкантам, которые стали включать джазовые импровизации в свои произведения, прежде всего выходцам из семей иммигрантов -Бенни Гудману и Арти Шоу. Таким образом иммигранты культура формировала образ «хорошего иммигранта» и иммигранты формировали американскую культуру.

description: We prove a 1999 conjecture of Veys, which says that the opposite of the log canonical threshold is the only possible pole of maximal order of Denef and Loeser's motivic zeta function associated with a germ of a regular function on a smooth variety over a field of characteristic zero. We apply similar methods to study the weight function on the Berkovich skeleton associated with a degeneration of Calabi-Yau varieties. Our results suggest that the weight function induces a flow on the non-archimedean analytification of the degeneration towards the Kontsevich-Soibelman skeleton.

description: Let F be a non-Archimedean local field and let G be a connected reductive affine algebraic F-group. Let I be an Iwahori subgroup of G(F) and denote by H(G; I) the Iwahori-Hecke algebra, i.e. the convolution algebra of complex-valued functions on G(F) which are left- and right-invariant by I-translations. This article proves that the Iwahori-Hecke algebra H(G; I) has both an Iwahori-Matsumoto Presentation and a Bernstein Presentation analogous to those for affine Hecke algebras on root data found in Lusztig's "Affine Hecke algebras and their graded version", and gives a basis (in other words, an explicit Bernstein Isomorphism) for the center Z[H(G; I)] also analogous to that found in loc. cit.

description: Recently, a family of interesting analytical brane solutions were found in $f(R)$ gravity with $f(R)=R+αR^2$ in Ref. [Phys. Lett. B 729, 127 (2014)]. In these solutions, inner brane structure can be turned on by tuning the value of the parameter $α$. In this paper, we investigate how the parameter $α$ affects the localization and the quasilocalization of the tensorial gravitons around these solutions. It is found that, in a range of $α$, despite the brane has an inner structure, there is no graviton resonance. However, in some other regions of the parameter space, although the brane has no internal structure, the effective potential for the graviton KK modes has a singular structure, and there exists a series of graviton resonant modes. The contribution of the massive graviton KK modes to the Newton's law of gravity is discussed shortly.

description: We study the capture of galactic dark matter particles (DMP) in two-body and few-body systems with a symplectic map description. This approach allows modeling the scattering of $10^{16}$ DMPs after following the time evolution of the captured particle on about $10^9$ orbital periods of the binary system. We obtain the DMP density distribution inside such systems and determine the enhancement factor of their density in a center vicinity compared to its galactic value as a function of the mass ratio of the bodies and the ratio of the body velocity to the velocity of the galactic DMP wind. We find that the enhancement factor can be on the order of tens of thousands.

description: This deliverable presents the work done to define the Usage Scenarios and derive from them the initial list of services. The objective is to identify the user needs and requirements for the proposed technical infrastructure of the I-NERGY project. The following deliverable is part of the WP2 task T2.1: AI-on-demand Energy Services Specifications. The result of the work is a collection of commonly agreed and methodologically aligned Usage Scenarios providing valuable inputs for continuation of the project work. The I-NERGY project aims at developing an open modular framework for supporting AI-on-demand in the energy sector by capitalising on state-of-the-art AI, IoT, semantics, federated learning and analytic tools. The Services and solutions will be tested and evaluated in nine pilots in Portugal, Spain, Italy, Greece, Croatia, Slovenia and Latvia, which span over the complete energy value chain. Collected and diverse Usage Scenarios of this deliverable present the initial work done in the project and bring starting ideas of the project closer to technical work packages. Furthermore, Usage Scenarios bridge the gap between initial ideas and process of shaping the solution, therefore facilitating the development of the solutions, which will be tested and evaluated in the I-NERGY pilots.

description: .Vitamin D deficiency is common in Irish adults, though there is limited research on its determinants, knowledge of vitamin D or indications for testing. We aimed to explore the determinants of vitamin D status in adults and examine knowledge and reasons for testing. The study population comprised adults who had serum 25-hydroxyvitamin D tested by general practitioners request at a Dublin Hospital in 2020. Questionnaires detailing dietary intake, sun exposure, ethnicity, biophysical factors and vitamin D knowledge were sent to a sample stratified by age, sex and vitamin D status. In total, there were 383 participants, mean age 56·0 (SD 16·6) years. Wintertime deficiency disproportionally affected non-white v. white (60 % v. 24 %, P < 0·001). The greatest predictors of deficiency were low vitamin D intake (< 10 μg/d) (P < 0·001) and non-white ethnicity (P = 0·006), followed by sun avoidance (P = 0·022). It was also more prevalent in those with lower body exposure when outdoors. The majority (86 %) identified vitamin D as important for bone health. However, 40 % were tested for non-clinical indications and half were not aware of the recommended daily allowance (RDA). Low vitamin D intake was the most important determinant of deficiency, but ethnicity and sun exposure habits were also significant predictors. The majority had no clear indication for testing and were not aware of the RDA. Public health policies to improve knowledge and vitamin D intake, especially for those of non-white ethnicity and with reduced sun exposure, should be considered.

description: We introduce dark mediator Dark matter (dmDM) where the dark and visible sectors are connected by at least one light mediator $ϕ$ carrying the same dark charge that stabilizes DM. $ϕ$ is coupled to the Standard Model via an operator $\bar q q ϕϕ^*/Λ$, and to dark matter via a Yukawa coupling $y_χ\overline{χ^c}χϕ$. Direct detection is realized as the $2\rightarrow3$ process $χN \rightarrow \bar χN ϕ$ at tree-level for $m_ϕ\lesssim 10 \ \mathrm{keV}$ and small Yukawa coupling, or alternatively as a loop-induced $2\rightarrow2$ process $χN \rightarrow χN$. We explore the direct-detection consequences of this scenario and find that a heavy $\mathcal{O}(100 \ \mathrm{GeV})$ dmDM candidate fakes different $\mathcal{O}(10 \ \mathrm{GeV})$ standard WIMPs in different experiments. Large portions of the dmDM parameter space are detectable above the irreducible neutrino background and not yet excluded by any bounds. Interestingly, for the $m_ϕ$ range leading to novel direct detection phenomenology, dmDM is also a form of Self-Interacting Dark Matter (SIDM), which resolves inconsistencies between dwarf galaxy observations and numerical simulations.

description: We show for a ring R of weak global dimension at most one that there is a bijection between the smashing subcategories of its derived category and the equivalence classes of homological epimorphisms starting in R. If, moreover, R is commutative, we prove that the compactly generated localizing subcategories correspond precisely to flat epimorphisms. We also classify smashing localizations of the derived category of any valuation domain, and provide an easy criterion for the Telescope Conjecture (TC) for any commutative ring of weak global dimension at most one. As a consequence, we show that the TC holds for any commutative von Neumann regular ring R, and it holds precisely for those Prüfer domains which are strongly discrete.

description: In this article we compare the halo mass function predicted by the excursion set theory with a drifting diffusive barrier against the results of N-body simulations for several cosmological models. This includes the standard LCDM case for a large range of halo masses, models with different types of primordial non-Gaussianity, and the Ratra-Peebles quintessence model of Dark Energy. We show that in all those cosmological scenarios, the abundance of dark matter halos can be described by a drifting diffusive barrier, where the two parameters describing the barrier have physical content. In the case of the Gaussian LCDM, the statistics are precise enough to actually predict those parameters at different redshifts from the initial conditions. Furthermore, we found that the stochasticity in the barrier is nonnegligible making the simple deterministic spherical collapse model a bad approximation even at very high halo masses. We also show that using the standard excursion set approach with a barrier inspired by peak patches leads to inconsistent predictions of the halo mass function.

description: A longstanding challenge in the foundations of quantum mechanics is the verification of alternative collapse theories despite their mathematical similarity to decoherence. To this end, we suggest a novel method based on dynamical decoupling. Experimental observation of nonzero saturation of the decoupling error in the limit of fast decoupling operations can provide evidence for alternative quantum theories. As part of the analysis we prove that unbounded Hamiltonians can always be decoupled, and provide novel dilations of Lindbladians.

Structured Machine Learning for Robotics

Publisher: name: Universit� degli studi di Genova

description: Machine Learning has become the essential tool for automating tasks that consist in predicting the output associated to a certain input. However many modern algorithms are mainly developed for the simple cases of classification and regression. Structured prediction is the field concerned with predicting outputs consisting of complex objects such as graphs, orientations or sequences. While these objects are often of practical interest, they do not have many of the mathematical properties that allow to design principled and computationally feasible algorithms with traditional techniques. In this thesis we investigate and develop algorithms for learning manifold-valued functions in the context of structured prediction. Differentiable manifolds are a mathematical abstraction used in many domains to describe sets with continuous constraints and non-Euclidean geometric properties. By taking a structured prediction approach we show how to define statistically consistent estimators for predicting elements of a manifold, in constrast to traditional structured predition algorithms that are restricted to output sets with finite cardinality. We introduce a wide range of applications that leverage manifolds structures. Above all, we study the case of the hyperbolic manifold, a space suited for representing hierarchical data. By representing supervised datasets within hyperbolic space we show how it is possible to invent new concepts in a previously known hierarchy and show promising results in hierarchical classification. We also study how modern structured approaches can help with practical robotics tasks, either improving performances in behavioural pipelines or showing more robust predictions for constrained tasks. Specifically, we show how structured prediction can be used to tackle inverse kinematics problems of redundant robots, accounting for the constraints of the robotic joints. We also consider the task of biological motion detection and show that by leveraging the sequence structure of video streams we significantly reduce the latency of the application. Our studies are complemented by empirical evaluations on both synthetic and real data.

description: La tesi, dal titolo ?Oggetto del contratto di lavoro e diritti della persona del lavoratore subordinato? affronta il tema classico, ma irto di difficolt�, della definizione dell'oggetto del contratto di lavoro subordinato, a partire dal dibattito attuale sulla funzione del diritto del lavoro. Dal dibattito sulla autonomia del diritto del lavoro rispetto alle ragioni dell'economia e del mercato, emerge l'urgenza di una ridefinizione dell'oggetto del contratto che si faccia carico della "cittadinanza" del lavoratore subordinato, titolare dei diritti fondamentali della persona garantiti dalla Costituzione, dal diritto dell'UE, dalle fonti internazionali.
EMPLOYEE'S PERCEPTION OF PERFORMANCE BASED INCENTIVE SCHEMES AND ITS INFLUENCE ON EMPLOYEE PRODUCTIVITY: THE CASE OF AFRICA VILLAGE FINANCIAL SERVICES S.C.
Creators: name: Melkamu Wogari
Publisher: name: Zenodo
Year: 2016

description: The general objective of the study was to investigate and assess the relationship between employee’s perception of performance based bonus and merit pay incentive scheme practices of Africa Village Financial Services and its influence on employee productivity. To undertake this general objective, four specific objectives with their underling hypothesis were designed and assessed by quantitative & qualitative research design. To set background information on the proposed hypothesis the theoretical, conceptual and other related literatures were reviewed and most of the literature finding implies that perception of employees of performance based bonus and merit pay incentive system has a significant and positive influence on employee productivity. The required data for conducting the research was obtained through structured and unstructured questionnaires. The structured questionnaire was adopted from two prior related studies. To check the reliability of the adopted instruments, the Chronbach’s coefficient alpha test was carried out. AVFS has only 98 total numbers of employees and the research was conducted on the entire population. Basically, a total of 98 questionnaires were distributed to the targeted employees, among these 90 were returned, which means 8 responses were remained unreturned.

description: Lagrange introduced the notion of Schwarzian derivative and Thurston discovered its mysterious properties playing a role similar to that of curvature on Riemannian manifolds. Here we continue our studies on the development of the Schwarzian derivative on Finsler manifolds. First, we obtain an integrability condition for the Möbius equations. Then we obtain a rigidity result as follows; Let $(M, F)$ be a connected complete Finsler manifold of positive constant Ricci curvature. If it admits non-trivial Möbius mapping, then $M$ is homeomorphic to the $n$-sphere. Finally, we reconfirm Thurston's hypothesis for complete Finsler manifolds and show that the Schwarzian derivative of a projective parameter plays the same role as the Ricci curvature on theses manifolds and could characterize a Bonnet-Mayer-type theorem.

description: We consider the degree-diameter problem for Cayley graphs of dihedral groups. We find upper and lower bounds on the maximum number of vertices of such a graph with diameter 2 and degree $d$. We completely determine the asymptotic behaviour of this class of graphs by showing that both limits are asymptotically $d^2/2$.

description: We present a comprehensive study of phase curves and secondary eclipses in the Kepler data set using all data from 16 quarters that were available in 2013-2014. Our sample consists of 20 confirmed planets with R_p > 4 R_e ,P < 10d, V_mag < 15. Here we derive their temperatures and albedos, with an eye towards constraining models for the formation and evolution of such planets. Where there was overlap our results confirm parameters derived by previous studies, whereas we present new results for Kepler 1b-8b, 12b-15b, 17b, 40b, 41b, 43b, 44b, 76b, 77b, and 412b derived in a consistent manner. We also present lightcurve analyses for Kepler 91b and Kepler 74b, which both show extra dimmings at times other than from the expected primary and secondary eclipses. Corrected for thermal emission we find most of the massive planets from our sample to be low in albedo (<0.1) with a few having higher albedo (>0.1).

description: Batch codes, introduced by Ishai, Kushilevitz, Ostrovsky and Sahai, represent the distributed storage of an $n$-element data set on $m$ servers in such a way that any batch of $k$ data items can be retrieved by reading at most one (or more generally, $t$) items from each server, while keeping the total storage over $m$ servers equal to $N$. This paper considers a class of batch codes (for $t=1$), called combinatorial batch codes (CBC), where each server stores a subset of a database. A CBC is called optimal if the total storage $N$ is minimal for given $n,m$, and $k$. A $c$-uniform CBC is a combinatorial batch code where each item is stored in exactly $c$ servers. A $c$-uniform CBC is called optimal if its parameter $n$ has maximum value for given $m$ and $k$. Optimal $c$-uniform CBCs have been known only for $c\in \{2,k-1,k-2\}$. In this paper we present new constructions of optimal CBCs in both the uniform and general settings, for values of the parameters where tight bounds have not been established previously. In the uniform setting, we provide constructions of two new families of optimal uniform codes with $c\sim \sqrt{k}$. Our constructions are based on affine planes and transversal designs.

Channel Diversity needed for Vector Space Interference Alignment
Creators: name: Li, Cheuk Ting
name: Özgür, Ayfer
Publisher: name: arXiv
Year: 2014
Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: We consider vector space interference alignment strategies over the $K$-user interference channel and derive an upper bound on the achievable degrees of freedom as a function of the channel diversity $L$, where the channel diversity is modeled by $L$ real-valued parallel channels with coefficients drawn from a non-degenerate joint distribution. The seminal work of Cadambe and Jafar shows that when $L$ is unbounded, vector space interference alignment can achieve $1/2$ degrees of freedom per user independent of the number of users $K$. However wireless channels have limited diversity in practice, dictated by their coherence time and bandwidth, and an important question is the number of degrees of freedom achievable at finite $L$. When $K=3$ and if $L$ is finite, Bresler et al show that the number of degrees of freedom achievable with vector space interference alignment is bounded away from $1/2$, and the gap decreases inversely proportional to $L$. In this paper, we show that when $K\geq4$, the gap is significantly larger. In particular, the gap to the optimal $1/2$ degrees of freedom per user can decrease at most like $1/\sqrt{L}$, and when $L$ is smaller than the order of $2^{(K-2)(K-3)}$, it decays at most like $1/\sqrt[4]{L}$.

Approximating longest spanning tree with neighborhoods
Creators: name: Biniaz, Ahmad
Publisher: name: Journal of Computational Geometry
Year: 2023

description: We study the following maximization problem in the Euclidean plane: Given a collection of neighborhoods (polygonal regions) in the plane, the goal is to select a point in each neighborhood so that the longest spanning tree on selected points has maximum length. It is not known whether or not this problem is NP-hard. We present an approximation algorithm with ratio $0.548$ for this problem. This improves the previous best known ratio of $0.511$. The presented algorithm takes linear time after computing a diameter. Even though our algorithm itself is fairly simple, its analysis is rather involved. In some part we deal with a minimization problem with multiple variables. We use a sequence of geometric transformations to reduce the number of variables and simplify the analysis.
