The role of collective motion in examples of coarsening and self-assembly
No full textThe simplest prescription for building a patterned structure from its constituents is to add particles, one at a time, to an appropriate template. However, self-organizing molecular and colloidal systems in nature can evolve in much more hierarchical ways. Specifically, constituents (or clusters of constituents) may aggregate to form clusters (or clusters of clusters) that serve as building blocks for later stages of assembly. Here we evaluate the character and consequences of such collective motion in a set of prototypical assembly processes. We do so using computer simulations in which a system's capacity for hierarchical dynamics can be controlled systematically. By explicitly allowing or suppressing collective motion, we quantify its effects. We find that coarsening within a two dimensional attractive lattice gas (and an analogous off-lattice model in three dimensions) is naturally dominated by collective motion over a broad range of temperatures and densities. Under such circumstances, cluster mobility inhibits the development of uniform coexisting phases, especially when macroscopic segregation is strongly favored by thermodynamics. By contrast, the assembly of model viral capsids is not frustrated but is instead facilitated by collective moves, which promote the orderly binding of intermediates consisting of several monomers
Effects of oxygen concentration in IVM/IVF on marmoset monkey oocyte maturation and embryo development
No full textUse of the over-the-scope-clip (OTSC) in non-variceal upper gastrointestinal bleeding in patients with severe cardiovascular comorbidities: a retrospective study
No full textAbstract
Introduction The over-the-scope-clip (OTSC) can potentially overcome
limitations of standard clips and achieve more efficient and reliable
hemostasis. Data on OTSC use for non-variceal upper gastrointestinal bleeding
(NVUGIB) in patients with cardiovascular comorbidities are currently limited.
Patients and methods We prospectively collected and retrospectively
analyzed our database from February 2009 to September 2015 from all patients who
underwent emergency endoscopy for high-risk NVUGIB in 2 academic centers and
were treated with OTSC as first-line (n = 81) or second-line therapy (n = 19).
Results One hundred patients mean age 72 (range 27 – 97 years) were
included in this study. Fifty-one percent (n = 51) had severe cardiovascular
co-morbidity (ischemic heart disease, congestive heart failure, hypertension,
valvular heart disease, peripheral arterial occlusive disease and atrial
fibrillation) and 73 % (n = 73) were on antiplatelet or/and anticoagulation
therapy. The median size of the treated ulcers was 3 cm (range 1 – 5 cm). In
94 % (n = 94) primary hemostasis with OTSC was achieved. Clinical long-term
success during a mean 6-month follow-up without rebleeding was 86 % (n = 86).
Conclusions In this cohort OTSC was demonstrated to be a safe and
effective first- or second-line treatment for NVUGIB in high-risk patients with
cardiovascular disease and complex, large ulcers. Meeting presentations:

Developmental and family history-based analysis of congenital fused labia phenotype in the captive common marmoset ( Callithrix jacchus )
No full textIn vitro matured oocytes have a higher developmental potential than in vivo matured oocytes after hormonal ovarian stimulation in Callithrix jacchus
No full textThe common marmoset, Callithrix jacchus, is an invaluable model in biomedical research. Its use includes genetic engineering applications, which require manipulations of oocytes and production of embryos in vitro. To maximize the recovery of oocytes suitable for embryo production and to fulfil the requirements of the 3R principles to the highest degree possible, optimization of ovarian stimulation protocols is crucial. Here, we compared the efficacy of two hormonal ovarian stimulation approaches: 1) stimulation of follicular growth with hFSH followed by triggering of oocyte maturation with hCG (FSH + hCG) and 2) stimulation with hFSH only (FSH-priming)
Application of the Envision Framework in Sustainable Rainwater Management: A Case Study on Rain-Garden Bands for Urban Road Drainage
No full text<p>Rainwater drainage plays a pivotal role in ensuring road safety. Traditional drainage systems not only entail significant costs but also necessitate ongoing maintenance. Current stormwater inlets often lead to inconsistent water absorption, and factors like climate change and infrastructure wear highlight the pressing need for improvement across developing and advanced nations. The paper introduces the city-sponge approach as a cost-effective and efficient alternative for managing rainwater. This method utilizes natural 'sponges' like rain gardens, permeable pavements, and green roofs.</p><p>The core proposition is the innovative 'rain-garden bands.' These serve dual purposes: facilitating swift and uniform road water absorption and reducing vehicular impact during accidents. Further, the poster delineates examples of designs for multi-tiered roads, integrating raised bike paths and walkways. Such designs counteract the energy of descending rainwater, preventing erosion and allowing for diverse urban vegetation. The proposed solution's foundation lies in a unique mathematical model to determine the optimal size of impingement plates for water collection.</p><p>The overarching goal is to foster safer urban roads through efficient rainwater management, eliminating the need for intricate, high-cost engineering solutions. Implementing the rain-garden bands with the city-sponge approach promises to deliver secure, dry roads, revolutionizing urban infrastructure design.</p>

Abstract
The article deals with the problem of higher education development in independent Ukraine in the period 1991-2002. The main ways of reforming the education system are outlined. The priorities of the state policy in the development of education are revealed. Areas of international cooperation in the field of education and science are of great importance.

Static properties of a warm dense uniform electron gas

Tkachenko , "Static properties of a warm dense uniform electron gas", Physics of Plasmas 28, 112704 (2021) https://doi.org/10.1063/5.0062259[EN] We show how the static dielectric function and other static characteristics of dense warm charged Fermi liquids can be obtained exclusively from the system static structure factor. The non-perturbative self-consistent method of moments is employed to extend onto quantum fluids, a similar reduction stemming from the fluctuation-dissipation theorem and other exact relations for classical one-component plasmas. The results are compared to and complement the numerical data obtained recently by the path-integral Monte Carlo method. Alternative theoretical approaches are discussed and employed as well.I.M.T. is grateful to M. Bonitz and T. Dornheim for several valuable discussions. The authors appreciate that M. Bonitz and T. Dornheim provided accurate path integral Monte Carlo simulation results. I.M.T. also acknowledges fruitful discussions with Yu. V. Arkhipov and L.
