description: We selected the claim that there is a significant relationship between family structure and work absorption, such that single, childless employees report lower work absorption than employees with other family structures (Hypothesis 1 in the original paper). This reflects the following statement from the paper’s abstract: “A survey of business school alumni (Study 1) revealed that single, childless workers reported lower absorption than workers with other family structures.” The work absorption construct captures the extent to which individuals become engrossed in their work. Hypothesis 1 predicted that single, childless respondents would report lower levels of absorption. The authors tested this hypothesis via ordinary least squares regression. As the authors expected, the effect of being single and childless on work absorption was negative and significant (b = -.31, SE = 0.13, p < .05).

description: We consider a semi-classical model to describe the origin of the spin-orbit interaction in a simple system such as the hydrogen atom. The interaction energy U is calculated in the rest-frame of the nucleus, around which an electron, having linear velocity v and magnetic dipole-moment mu, travels in a circular orbit. The interaction energy U is due to the coupling of the induced electric dipole p=(v/c)x mu with the electric field En of the nucleus. Assuming the radius of the electron's orbit remains constant during a spin-flip transition, our model predicts that the energy of the system changes by Delta_E = U/2, the factor 1/2 emerging naturally as a consequence of equilibrium and the change of the kinetic energy of the electron. The correct 1/2 factor for the spin-orbit coupling energy is thus derived without the need to invoke the well-known Thomas precession in the rest-frame of the electron.

description: In Part I of this study, we analyzed the motion of inertial particles in isotropic turbulence in the absence of gravity using direct numerical simulation (DNS). Here, in Part II, we introduce gravity and study its effect over a wide range of flow Reynolds numbers, Froude numbers, and particle Stokes numbers. We see that gravity causes particles to sample the flow more uniformly and reduces the time particles can spend interacting with the underlying turbulence. We also find that gravity tends to increase inertial particle accelerations, and we introduce a model to explain that effect. We then analyze the particle relative velocities and radial distribution functions (RDFs), which are generally seen to be independent of Reynolds number for low and moderate Kolmogorov-scale Stokes numbers $St$. We see that gravity causes particle relative velocities to decrease, and that the relative velocities have higher scaling exponents with gravity. We observe that gravity has a non-trivial effect on clustering, acting to decrease clustering at low $St$ and to increase clustering at high $St$. By considering the effect of gravity on the clustering mechanisms described in the theory of Zaichik & Alipchenkov (New J. Phys., 11:103018, 2009), we provide an explanation for this non-trivial effect of gravity. We also show that when the effects of gravity are accounted for in the theory of Zaichik & Alipchenkov, the results compare favorably with DNS. The relative velocities and RDFs exhibit considerable anisotropy at small separations, and this anisotropy is quantified using spherical harmonic functions. We use the relative velocities and the RDFs to compute the particle collision kernels, and find that the collision kernel remains as it was for the case without gravity, namely nearly independent of Reynolds number for low and moderate $St$.

description: We investigate smooth and sparse optimal control problems for convective FitzHugh-Nagumo equation with travelling wave solutions in moving excitable media. The cost function includes distributed space-time and terminal observations or targets. The state and adjoint equations are discretized in space by symmetric interior point Galerkin (SIPG) method and by backward Euler method in time. Several numerical results are presented for the control of the travelling waves. We also show numerically the validity of the second order optimality conditions for the local solutions of the sparse optimal control problem for vanishing Tikhonov regularization parameter. Further, we estimate the distance between the discrete control and associated local optima numerically by the help of the perturbation method and the smallest eigenvalue of the reduced Hessian.

description: Arthritis is a major public health issue that carries an enormous burden for our nation in terms of disability, healthcare costs and economic costs. Physical activity programs are a public health cost-effective solution proven to help manage arthritis symptoms and help people achieve the recommended levels of daily activity of at least 30 minutes of physical activity five times per week (Barbour, Helmick, Boring, Brady, 2017). One of these evidence-based programs appropriate for adults with arthritis is Walk With Ease (WWE). WWE is a low-cost intervention that can be easily implemented by a community organization. However, a major issue for public health leaders in communities is determining what program format to implement for potential participants in the face of limited resources, a diverse population base and the marketing strategies to disseminate. Knowing which program would best appeal to potential participants can help administrators make these decisions about WWE implementation. An analysis of pre- and post-program WWE data identified that white non-Hispanic, educated females in “good” health were the majority of participants in this program in both the self-directed and group-led formats. However, differences began to emerge when other demographics were examined such as ethnicity and age. Participants who were younger in age, more physically active, and have fewer chronic conditions were more likely to participate in the self-directed format. African American, Asian, Hawaiian or Pacific Islanders, were more likely to enroll in the group-led format as compared to whites, and Native American Indians or Alaska Natives. This paper will contribute to the development of an evidence-base to inform decision-making about marketing strategies for WWE using data from a mini-grant program along with lessons learned from other physical activity and self-management programs. Continued research to understand the Walk With Ease format appeal will help to determine marketing strategies to reach a variety of audiences and improve the dissemination of this program.

description: Seiring dengan semakin berharganya nilai sebuah informasi dan semakin banyak sumber-sumber informasi, maka semakin banyak pula kebutuhan manusia untuk dapat menemukan informasi yang sesuai keperluannya dengan cepat. Information Retrieval (Perolehan Informasi) merupakan suatu pencarian informasi(biasanya berupa dokumen) yang didasarkan pada suatu query (inputan user) yang diharapkan dapat memenuhi keinginan user dari dokumen yang ada. Dua aspek penting dalam konsep Information Retrieval yang diterapkan dalam sebuah perancangan mesin pencari yaitu repesentasi dari informasi dan pengukuran yang akan mengukur nilai kesamaan antara dua obyek. Informasi yang dapat direpresentasikan menjadi sebuah obyek yang direpresentasikan dalam berbagai bentuk dan model (heterogeneous). Keadaan ini mengakibatkan bahwa pencarian untuk suatu obyek informasi yang diinginkan akan dapat dipetakan kepada beberapa obyek informati yang dinilai relevan. Relevansi dua informasi di-ukur dari keberadaan kata kunci (keyword) dan bobotnya. Konsekuensi logis atas keadaan ini adalah bahwa dalam melakukan pencarian obyek yang diinginkan, ditemukan terdapat ketidakpastian (uncertainly) terhadap penggunaan keyword pada query oleh pengguna dengan keberadaan keyword pada dokumen. Pada penelitian ini akan difokuskan pada studi efektifitas vektor model dengan menggunakan algoritma steming poter untuk membentuk kata-kata menjadi sebuah kata baku serta pembobotan frekuwensi term untuk menentukan tingkat kepentingan setiap indeks term dalam sebuah dokumen dan fungsi kesamaan cosine dalam mengukur kemiripan queri dengan dokumen. Hasil pengujian nilai kualitas rata-rata precesion dan recall bahwa untuk semua bentuk query pencarian dokumen mempunyai nilai precesion 100% artinya baik pencarian berdasarkan bentuk query isi, judul dan dokumen mempunyai precesion yang baik sedangkan hasil pengujian recall menunjukkan hasil yang berbeda, dimana pencarian berdasarkan bentuk queri isi dokumen menempati recall tertinggi sebesar 90%, sedangkan pencarian berdasarkan bentuk queri judul dokumen dengan nilai recall 70% dan pencarian berdasarkan bentuk query dokumen menempati posisi terendah dengan recall 33%.

description: We present an analysis of optical and infrared spectra of the recurrent nova RS Oph obtained during between 2006 and 2009. The best fit to the optical spectrum for 2006 September 28 gives effective temperature Tef = 3900~K for log g = 2.0, while for log g = 0.0 we find Tef = 4700~K, and a comparison with template stellar spectra provides Tef $\sim$ 4500 K. The observed spectral energy distribution (SED), and the intensities of the emission lines, vary on short ($\sim 1$~day) time-scales, due to disc variability. We invoke a simple one-component model for the accretion disc, and a model with a hot boundary layer, with high ($\sim 3.9 \times 10^{-6}$ \Mdot) and low ($\sim 2 \times 10^{-8}$ \Mdot) accretion rates, respectively. Fits to the accretion disc-extracted infrared spectrum (2008 July 15) yield effective temperatures for the red giant of Tef = 3800 +/- 100~K (log g = 2.0) and Tef = 3700 +/- 100~K (log g = 0.0). Furthermore, using a more sophisticated approach, we reproduced the optical and infrared SEDs of the red giant in the RS Oph system with a two-component model atmosphere, in which 90\% of the surface has Tef = 3600 K and 10\% has Tef = 5000~K. Such structure could be due to irradiation of the red giant by the white dwarf.

We provide a number of innovations on the standard procedures and address many practical implementation issues including the addition of redundant variables, interactive visualisations and approximating logistic models with linear models. An option is provided that combines our bootstrap approach with glmnet for higher dimensional models. The plots and graphical user interface leverage state of the art web technologies to facilitate interaction with the results. The speed of implementation comes from the leaps package and cross-platform multicore support.

description: We study Feynman integrals in the representation with Schwinger parameters and derive recursive integral formulas for massless 3- and 4-point functions. Properties of analytic (including dimensional) regularization are summarized and we prove that in the Euclidean region, each Feynman integral can be written as a linear combination of convergent Feynman integrals. This means that one can choose a basis of convergent master integrals and need not evaluate any divergent Feynman graph directly. Secondly we give a self-contained account of hyperlogarithms and explain in detail the algorithms needed for their application to the evaluation of multivariate integrals. We define a new method to track singularities of such integrals and present a computer program that implements the integration method. As our main result, we prove the existence of infinite families of massless 3- and 4-point graphs (including the ladder box graphs with arbitrary loop number and their minors) whose Feynman integrals can be expressed in terms of multiple polylogarithms, to all orders in the epsilon-expansion. These integrals can be computed effectively with the presented program. We include interesting examples of explicit results for Feynman integrals with up to 6 loops. In particular we present the first exactly computed counterterm in massless phi^4 theory which is not a multiple zeta value, but a linear combination of multiple polylogarithms at primitive sixth roots of unity (and divided by $\sqrt{3}$). To this end we derive a parity result on the reducibility of the real- and imaginary parts of such numbers into products and terms of lower depth.

Year: 2019

description: East Africa is a vibrant, growing community made up of the nations of Burundi, Kenya, Rwanda, Tanzania, Uganda and South Sudan. These countries and their neighbors face the highest burden of death and disability from emergencies in the world coupled with poor access to emergency care.The past decade has witnessed the debut of a bright and talented generation of young professionals eager to improve emergency care in East Africa. They face unique challenges and opportunities ahead. These emergency care providers will be called upon to define the role and limits of their profession, lead teams and departments, apply innovation and technology to accelerate change, develop and disseminate evidence-based practices, ensure accountability and quality of care, align stakeholders across fragmented sectors, shape health policy, and build systems to extend the reach of timely, effective emergency care to all who need it. East African emergency care providers depend not only on expert clinical knowledge and technical skills, but on their capabilities as public health leaders and health strategists in their community. This paper outlines the challenges and opportunities they face and provides recommendations for ensuring they have the support necessary to be successful.

description: This report of the BRIDGES project investigates as to how locally dominant and EU-promoted narratives related to migration, interact and influence the decision-making of potential migrants in the Gambia. The study is based on focus groups and in-depth interviews with 60 Gambian youngsters who think about migrating abroad. The report starts by outlining the dominant - or Master - narratives on migration and Europe in the Gambia. These narratives put to the forefront the opportunities for a positive life change enabled by a person migrating to Europe. Europe is associated with (professional or educational) opportunities and a probability of getting high(er) living standards and achieving social mobility. Practically every participant tended to see a positive cost-benefit calculus in favour of migration, yet some considered the risks to outweigh the benefits of irregular migration. The research shows that the messages promoted in EU-funded information campaigns struggle to unfold an influence in view of the dominant Master narratives on migration and Europe. Aggregately speaking, potential migrants in the Gambia rely little on the information of EU-funded campaigns when making decisions. The exception are potential migrants who are already sensitive about the risks of the journey. The campaigns are able to reinforce existing doubts, thereby tipping the overall calculus in some cases. That said, information is only one factor among others influencing migratory decision-making. More relevant ones are the actual livelihood opportunities or a lack of prospects in the Gambia as well as the social prestige that can be gained through migration.
Preventing and treating burnout among physicians in Japan
Creators: name: Endo, Hideki

Year: 2019

description: The work environment of physicians is demanding and contributes to their poor well-being. Physicians are often burned out, and their state of burnout affects not only the quality of their lives but also the quality of healthcare services. The health of burned-out physicians deteriorates mentally, physically, and socially. Furthermore, burnout among physicians is associated with poor patient satisfaction and increased medical error. The wide range of consequences has urged policy-makers and local leaders to begin taking actions. The aim of this paper is to assess potential policy options to prevent burnout among physicians in Japan. The severity of the burnout epidemic, the theories and concepts related to burnout, and the socio-political environment in Japan are analyzed in order to suggest policy solutions. The role of leadership in the effective implementation of policy change is also reviewed. Between 20% to 40% of physicians from various disciplines in Japan are estimated to be burned out, which poses a threat to their lives and to the healthcare system. According to the conservation of resources theory, preventing loss of resources and enhancing opportunities for resource gain are key strategies for preventing burnout. Factors such as long work hours and poor access to mental healthcare are considered to be threats to physicians’ resources yet there was no strict enforcement of limiting the amount of overtime work until recently. As part of its labor reform strategy, the Japanese Ministry of Health, Labour and Welfare recommended limiting the amount of overtime and suggested shifting and sharing physician tasks to other healthcare workers. After examining a range of policy options for preventing burnout at the organizational and national policy levels using a public health lens, work-hour limitation combined with task shifting and sharing and building an organizational structure focused on improving the well-being of physicians are considered effective policy options for preventing loss and enhancing gain of physicians’ resources. Along with these policies, leadership plays an important role in policy implementation. Leaders must set a clear vision, communicate with stakeholders, and build a coalition to implement the policy. Additionally, chief officers at hospitals should employ leadership skills and tools, such as setting SMART objectives and using logic models, to accelerate change and achieve the goal of preventing burnout among physicians in Japan.

The effect of Reynolds number on inertial particle dynamics in isotropic turbulence. Part I: Simulations without gravitational effects

description: In this study, we analyze the statistics of both individual inertial particles and inertial particle pairs in direct numerical simulations of homogeneous isotropic turbulence in the absence of gravity. The effect of the Taylor microscale Reynolds number $R_λ$ on the particle statistics is examined over the largest range to date (from $R_λ= 88-597$). We first explore the effect of preferential sampling on the single-particle statistics, and use our understanding of preferential sampling to provide a physical explanation for many of the trends in the particle velocity gradients, kinetic energies, and accelerations at low $St$. As $St$ increases, inertial filtering effects become more important, causing the particle kinetic energies and accelerations to decrease. We then consider particle-pair statistics, and focus our attention on the relative velocities and radial distribution functions (RDFs) of the particles. The relative velocity statistics indicate that preferential-sampling effects are important for $St \lesssim 0.1$ and that path-history/non-local effects become increasingly important for $St \gtrsim 0.2$. The lower-order relative velocity statistics are only weakly sensitive to changes in Reynolds number at low $St$. We find that the RDFs peak near $St$ of order unity, that they exhibit power-law scaling for low and intermediate $St$, and that they are largely independent of Reynolds number for low and intermediate $St$. We also observe that at large $St$, changes in the RDF are related to changes the scaling exponents of the relative velocity variances. The particle collision kernel is found to be largely insensitive to the flow Reynolds number, suggesting that relatively low-Reynolds-number simulations may be able to capture much of the relevant physics of droplet collisions and growth in the adiabatic cores of atmospheric clouds.

It is required that $μ(x)$ and $ε(x)$ are symmetric and positive definite uniformly for $x\inΩ$, and that $μ,ε\in L^{\infty}(Ω,\mathbb{R}^{3\times 3})$.

description: The continuous integration of experimental data into coherent models of the brain is an increasing challenge of modern neuroscience. Such models provide a bridge between structure and activity, and identify the mechanisms giving rise to experimental observations. Nevertheless, structurally realistic network models of spiking neurons are necessarily underconstrained even if experimental data on brain connectivity are incorporated to the best of our knowledge. Guided by physiological observations, any model must therefore explore the parameter ranges within the uncertainty of the data. Based on simulation results alone, however, the mechanisms underlying stable and physiologically realistic activity often remain obscure. We here employ a mean-field reduction of the dynamics, which allows us to include activity constraints into the process of model construction. We shape the phase space of a multi-scale network model of the vision-related areas of macaque cortex by systematically refining its connectivity. Fundamental constraints on the activity, i.e., prohibiting quiescence and requiring global stability, prove sufficient to obtain realistic layer- and area-specific activity. Only small adaptations of the structure are required, showing that the network operates close to an instability. The procedure identifies components of the network critical to its collective dynamics and creates hypotheses for structural data and future experiments. The method can be applied to networks involving any neuron model with a known gain function.

description: How can we understand the success of a narrative in France? To answer this question, three events are studied: the attack on the Nice basilica in 2020, the intrusions on the Channel Tunnel in 2015 and the burkini controversy in 2016. This report uses a mixed qualitative and quantitative analysis of three media: press, television and Twitter. Ten interviews with journalists complement the data. The results show, among other things, the ease with which hatred of migrants and Muslims is propagated in Le Figaro and on Twitter. Moreover, newscasts are benevolent towards this population compared to the press. Several factors are put forward in the report to understand these rhetorical differences
Effect of videotaped eyewitness identification evidence on legal decisions

description: Scholars recommend that police videorecord eyewitness identification procedures to preserve an accurate record of the conditions under which the eyewitness made an identification. It is necessary to understand how this new form of evidence impacts legal decisions. We will conduct a study examining how the presence of videorecorded eyewitness evidence impacts jurors’ decisions. We will build on previous research that examined how the presence of videorecorded eyewitness evidence with different administrator behaviors influenced jurors’ decisions (Modjadidi & Kovera, 2018). Jurors rated single-blind identification procedures (i.e., those where the administrator knows the identity of the suspect) as significantly more suggestive than double-blind procedures (i.e., those where the administrator does not know the identity of the suspect) and were consequently less likely to convict a defendant on the basis of a single-blind lineup. In addition, jurors were less likely to believe the eyewitness when they viewed a video of the identification procedure regardless of whether it was single- or double-blind. However, this study focused solely on the behavior of the administrator and not on the behavior of the eyewitness or their combination. It might be the case that jurors adjust their decisions based on the eyewitness’s behavior during a single- or double-blind procedure. Because videos will provide information about both the administrator’s and the eyewitness’s behavior during the lineup procedure, it is important to examine how each of these independently impacts jurors’ decisions. The results of this study will supplement the current knowledge in our field about the impact of videorecorded evidence and will illuminate the effects of the new recommendation.
Disaster Planning for Families

description: Since 2007, 80% of Americans have experienced a weather-related disaster but only 39% of Americans have a disaster plan (Federal Emergency Management Agency FEMA, 2015). These statistics showcase a lack of public health preparedness at the individual level that needs to be addressed by local public health leaders. Public health preparedness is the responsibility of not only the community itself but also the individuals within the community. An increase in prepared and resilient individuals of the community will limit undue burdens on the limited number of resources available for response to disasters. Local public health leaders play a vital role in supporting the communities’ disaster response system. Americans rely on their relationship with local public health leaders instead of FEMA officials when facing a disaster (Sadiq, Tharp, & Graham, 2016). In this paper, the North Carolina Department of Health and Human Services (NCDHHS) Family Disaster Plan (NCDHHS, 2007), the National Disaster Education Coalition Family Disaster Plan (National Disaster Education Coalition, n.d.), the FEMA Family Emergency Planning Guide (FEMA, 2011), the American Red Cross Family Disaster Plan (American Red Cross, n.d.), Preparedness Month, Ready Wrigley, and Zombie Preparedness (Centers for Disease Control and Prevention CDC, 2018b) were compared to the CDC personal preparedness domains and components for public health impact and feasibility. This paper analyzes current family disaster guides, plans, and initiatives and provides recommendations for local public health leaders to create an inclusive family disaster planning initiative to address public health preparedness and resiliency at the individual level.

description: This paper studies fixed rate vector quantisation for noisy networked control systems (NCSs) with correlated packet dropouts. In particular, a discrete-time linear time invariant system is to be controlled over an error-prone digital channel. The controller uses (quantized) packetized predictive control to reduce the impact of packet losses. The proposed vector quantizer is based on sparse regression codes (SPARC), which have recently been shown to be efficient in open-loop systems when coding white Gaussian sources. The dictionaries in existing design of SPARCs consist of independent and identically distributed (i.i.d.) Gaussian entries. However, we show that a significant gain can be achieved by using Gaussian dictionaries that are shaped according to the second-order statistics of the NCS in question. Furthermore, to avoid training of the dictionaries, we provide closed-form expressions for the required second-order statistics in the absence of quantization.

description: We construct the dagger realization functor for analytic motives over non-archimedean fields of mixed characteristic, as well as the Monsky-Washnitzer realization functor for algebraic motives over a discrete field of positive characteristic. In particular, the motivic language on the classic étale site provides a new direct definition of the overconvergent de Rham cohomology and rigid cohomology and shows that their finite dimensionality follows formally from the one of Betti cohomology for smooth projective complex varieties.

description: The realization of phononic computing is held hostage by the lack of high performance thermal devices. Here we show through theoretical analysis and molecular dynamics simulations that unprecedented thermal rectification factors (as large as 1.20) can be achieved utilizing the phase dependent thermal conductivity of polyethylene nanofibers. More importantly, such high thermal rectifications only need very small temperature differences (< 20 oC) across the device, which is a significant advantage over other thermal diodes which need temperature biases on the order of the operating temperature. Taking this into consideration, we show that the dimensionless temperature-scaled rectification factors of the polymer nanofiber diodes range from 12 to 25 - much larger than other thermal diodes (< 8). The polymer nanofiber thermal diode consists of a crystalline portion whose thermal conductivity is highly phase-sensitive and a cross-linked portion which has a stable phase. Nanoscale size effect can be utilized to tune the phase transition temperature of the crystalline portion, enabling thermal diodes capable of operating at different temperatures. This work will be instrumental to the design of high performance, inexpensive and easily processible thermal devices, based on which thermal circuits can be built to ultimately enable phononic computing.
A world-line framework for 1D Topological Conformal sigma-models

description: We use world-line methods for pseudo-supersymmetry to construct $sl(2|1)$-invariant actions for the $(2,2,0)$ chiral and ($1,2,1)$ real supermultiplets of the twisted $D$-module representations of the $sl(2|1)$ superalgebra. The derived one-dimensional topological conformal $σ$-models are invariant under nilpotent operators. The actions are constructed for both parabolic and hyperbolic/trigonometric realizations (with extra potential terms in the latter case). The scaling dimension $λ$ of the supermultiplets defines a coupling constant, $2λ+1$, the free theories being recovered at $λ=-\frac{1}{2}$. We also present, generalizing previous works, the $D$-module representations of one-dimensional superconformal algebras induced by ${\cal N}=(p,q)$ pseudo-supersymmetry acting on $(k,n,n-k)$ supermultiplets. Besides $sl(2|1)$, we obtain the superalgebras $A(1,1)$, $D(2,1;α)$, $D(3,1)$, $D(4,1)$, $A(2,1)$ from $(p,q)= (1,1), (2,2), (3,3), (4,4), (5,1)$, at given $k,n$ and critical values of $λ$.

description: We survey some recent results in hopfological algebra and the program of categorification at prime roots of unity. A categorical Jones-Wenzl projector at prime roots of unity is studied, and it is shown that this projector is hopfologically finite in special characteristics, while generically it is infinite.

description: We measure the photometric rotation periods of the components of multiple systems in young stellar associations to investigate the causes of the observed rotation period dispersion. We present the case of the wide binary AG Tri in the 23-Myr young beta Pictoris Association consisting of K4 + M1 dwarfs. Our multi-band, multi-season photometric monitoring allowed us to measure the rotation periods of both components P_A = 12.4d and P_B = 4.66d, to detect a prominent magnetic activity in the photosphere, likely responsible for the measured radial velocity variations, and for the first time, a flare event on the M1 component AG Tri B. We investigate either the possibility that the faster rotating component may have suffered an enhanced primordial disc dispersal, starting its PMS spin-up earlier than the slower rotating component, or the possibility that the formation of a debris disc may have prevented AG Tri A from gaining part of the angular momentum from the accreting disc.

description: This report is a part of deliverable “D.6.2. Report on migration and demographic patterns in the EU
 CEE countries and potential source countries” from the project FUME – Future Migration Scenarios
 for Europe (870649), financed with the Horizon 2020 programme. In particular, this country report
 focuses on critical analysis of migration data in Bulgaria. The analysis consists of an overview of
 stock and flow data on migrants, including such dimensions as age groups, gender, country of
 origin, education levels and length of residence. This report is a first step in analytical exercise of
 this deliverable which aims to determine migration potential from and to Bulgaria and furthermore,
 to provide necessary data input for fine-tuning of FUME migration projection model. The Republic of Bulgaria is a country in Southeast Europe, which joined the European Union in
 2007, but so far is outside of the Schengen zone. It has traditionally been a country of emigration,
 i.e., more Bulgarians used to leave the country than foreign-born persons arrived. In the last
 decade, immigration has been increasing but, nevertheless, it still remains at a relatively low
 level in comparison to other EU countries. The report presents a historical overview of migration
 processes in Bulgaria, underlying mainly recent emigration tendencies. Then, migration stocks and
 flows are analyzed using mainly national data complemented by research reports. Moreover, the
 report presents migration data estimations provided by Abel and Cohen (2019).
Simultaneous regulation of cell size and chromosome replication in bacteria

description: Bacteria are able to maintain a narrow distribution of cell sizes by regulating the timing of cell divisions. In rich nutrient conditions, cells divide much faster than their chromosomes replicate. This implies that cells maintain multiple rounds of chromosome replication per cell division by regulating the timing of chromosome replications. Here, we show that both cell size and chromosome replication may be simultaneously regulated by the long-standing initiator accumulation strategy. The strategy proposes that initiators are produced in proportion to the volume increase and is accumulated at each origin of replication, and chromosome replication is initiated when a critical amount per origin has accumulated. We show that this model maps to the incremental model of size control, which was previously shown to reproduce experimentally observed correlations between various events in the cell cycle and explains the exponential dependence of cell size on the growth rate of the cell. Furthermore, we show that this model also leads to the efficient regulation of the timing of initiation and the number of origins consistent with existing experimental results.

description: We investigate the average entropy of a subsystem within a global unitary orbit of a given mixed bipartite state in the finite-dimensional space. Without working out the closed-form expression of such average entropy for the mixed state case, we provide an analytical lower bound for this average entropy. In deriving this analytical lower bound, we get some useful by-products of independent interest. We also apply these results to estimate average correlation along a global unitary orbit of a given mixed bipartite state. When the notion of von Neumann entropy is replaced by linear entropy, the similar problem can be considered also, and moreover the exact average linear entropy formula is derived for a subsystem over a global unitary orbit of a mixed bipartite state.
