Effect of extreme weather on the breeding parameters of great tits Parus major: comparison of two very different seasons

Abstract Climate change and extreme weather events may be seen as an opportunity to help understand the mechanisms by which birds adjust their breeding parameters to environmental variability. In the breeding season of 2020, several factors, such as a prolonged drought period, a relatively warm winter with no snow cover, and a cold spring (the coldest May in Poland since 1991) affected many bird populations in Poland. The great tit Parus major tended to produce much smaller clutches, much fewer fledglings, and had very low breeding success, increasing with the progress of the breeding season in 2020, in contrast to the more typical breeding season characterised by average weather parameters in 2018. In light of the results obtained, we agree with the view that the phenotypic plasticity of the breeding parameters of the studied birds, such as phenology, may be insufficient to adjust to the upcoming extreme weather events. Additionally, further examining of the impact of extreme weather events on the breeding biology of animals is an important goal for future studies.
Antibacterial and Angiogenic Poly(ionic liquid) Hydrogels

Wounds, particularly under low-hydration conditions, require more time to repair successfully. Therefore, there is an urgent need to develop wound dressings that can accelerate wound healing. Hydrogels, which can maintain a moist environment around the wound and allow gas to pass through the material, act as antibacterial hydrogels as dressings and have great application value in the treatment of wounds. In addition, wound dressings (hydrogels) containing antibacterial capacity have lasting antibacterial effects and reduce damage to cells. In this work, we firstly synthesized two antibacterial agents: imidazolium poly(ionic liquids) containing sulfhydryl (Imidazole-SH) and ε-Poly(lysine) containing SH (EPL-SH). Then, lysine as a cross-linking agent, by “thiol-ene” click reaction, was mixed with Deferoxamine (DFO) to prepare the antibacterial hydrogels. The in vitro assays showed that the hydrogels could effectively kill Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus). In addition, it also could reduce the inflammatory response produced by Lipopolysaccharide (LPS). More importantly, according to the transwell and angiogenesis assays, DFO-incorporated hydrogels promoted the migration and vascular repair of human umbilical vein endothelial cells (HUVECs). All the results revealed that the hydrogels provided new strategies for wound dressings.

Solar Reactor Review

This research paper presents a detailed review of the recent advances concerned with carrying out efficient solar chemical reactions by reviewing the most recent reactors available in the literature that use solid-gas reactions or pyrolysis processes. Major research groups in solar chemistry design and manufacture a wide range of solar reactor configurations, widths, and sizes, including directly radioactive particles. Solar reactors heat up to 1000℃ and can be utilized to store chemical thermal energy in concentrated solar power facilities (CSP). Reactor efficiency is better in bed reactors notably in rotating pyrolysis, fluidized bed reactors with solid gas, and fixed-bed reactor systems. Finally, their description, schematics, and key performance parameters are presented for chemical reactions.
Skeletal muscle and related protein expression as prognostic factors in thymic squamous cell carcinoma

Background Sarcopenia and its marker, the psoas muscle index (PMI), have attracted attention as prognostic factors for various types of cancers. The fragile X-related 1 (FXR1) gene is highly expressed in myocytes, and FXR1 overexpression is a candidate biomarker for poor survival in several types of cancers. Thymic squamous cell carcinoma (TSQCC) is rare, and no studies assessing its prognostic factors, particularly in terms of skeletal muscle mass and FXR1 expression, are available. Methods We retrospectively investigated the prognostic significance of PMI in 34 patients who underwent TSQCC resection, considering the status of FXR1 and tumor programmed death-ligand 1 (PD-L1). PMI was calculated from the bilateral psoas muscle using preoperative computed tomography (CT). Patients were divided into two groups: low PMI (<58.2%, n=17) and normal PMI (≥58.2%, n=17). Immunohistochemical analysis was performed to determine the FXR1 and PD-L1 expression levels. Results Low PMI was significantly associated with worse overall survival (OS) (5-year survival rate; 86% vs. 100%; P=0.026) and marginally associated with worse disease-free survival (DFS) (5-year survival rate; 39% vs. 66%; P=0.090) compared with normal PMI. The immunohistochemical analysis revealed that the FXR1 intensity score (0–1+: 6% vs. 0%; 2+–3+: 94% vs. 100%; P=0.31), median FXR1 distribution (95% vs. 90%; P=0.63), and PD-L1 status (high: 47% vs. 59%; P=0.49) were not significantly different between the two groups. Conclusions Our findings suggest that PMI might be considered as a potential prognostic factor in TSQCC and that FXR1 is widely expressed regardless of the PMI status. Skeletal muscle mass may play a role in the prognosis of TSQCC.
On well-posedness of generalized Korteweg-de Vries equation in scale critical ^L^r space

The purpose of this paper is to study local and global well-posedness of initial value problem for generalized Korteweg-de Vries (gKdV) equation in ^L^r. We show (large data) local well-posedness, small data global well-posedness, and small data scattering for gKdV equation in the scale critical ^L^r space. A key ingredient is a Stein-Tomas type inequality for the Airy equation, which generalizes usual Strichartz estimates for ^L^r-framework.
Flexible Temperature Sensor Based on Binary Polymer Composite Thin Film

A high performance flexible temperature sensor for environmental and health monitoring has been fabricated using various combinations of composite blend of poly vinylidene fluoride / poly (3,4-ethylenedioxythiophene)-poly (styrenesulfonate) (PVDF/PEDOT:PSS). The response curves and working principle were investigated and sensors were then fabricated to achieve highly linear and stable response for a wide range of temperature sensing (25°C to 120°C). The film was fabricated on flexible polyethylene terephthalate (PET) substrate using spin coating. The copper electrodes were fabricated using copper tape. The sensors showed stable and close to linear response of impedance change by varying temperature in the range 25°C to 120°C. The resistance of the sensors changed from ~70MΩ to ~52MΩ for the temperature change in the range 25°C to 120°C. The sensors are aimed to replace low performance, complex and expensive sensors in the market for environmental and health monitoring applications.
Inverse boundary value problem for the Helmholtz equation: Multi-level approach and iterative reconstruction

We study the inverse boundary value problem for the Helmholtz equation using the Dirichlet-to-Neumann map at selected frequency as the data. We develop an explicit reconstruction of the wavespeed using a multi-level nonlinear projected steepest descent iterative scheme in Banach spaces. We consider wavespeeds containing discontinuities. A conditional Lipschitz stability estimate for the inverse problem holds for wavespeeds of the form of a linear combination of piecewise constant functions with an underlying domain partitioning, and gives a framework in which the scheme converges. The stability constant grows exponentially as the number of subdomains in the domain partitioning increases. To mitigate this growth of the stability constant, we introduce hierarchical compressive approximations of the solution to the inverse problem with piecewise constant functions. We establish an optimal bound of the stability constant, which leads to a condition on the compression rate pertaining to these approximations.
A Novel Design Method of High Throughput Blockchain for 6G Networks: Performance Analysis and Optimization Model

Sharing is undoubtedly one of the most important features of 6G networks, and blockchain can provide an extended trust-as-a-service (TAAS) distributed sharing solution for 6G networks. However, as a special distributed technology system, blockchain naturally needs to face the “impossible triangle” problem: in the case of ensuring security and decentralization, scalability will inevitably become the Achilles heel of the blockchain system. This article will design a high-throughput blockchain system for 6G networks to achieve trusted sharing and efficient scheduling of network infrastructure, assist future networks in integrating an open Internet architecture, and realize the combination of openness and distributed control. We adopt a shard blockchain design and incorporate digital twins and federated learning; formulate an optimization model for maximizing the throughput of the blockchain network by getting the optimal number of shards, also analyzing other factors affecting the throughput such as service distribution; propose a security performance analysis model for the blockchain network to describe the measures taken against the Byzantine attacks on the network. Analysis and simulation results show that the transaction throughput of the proposed method can reach more than 30 times larger than that of a nonsharding scheme. They also show that when one-third of the nodes in the system are attacked, the consensus of the system is hardly affected; even if the number of nodes being attacked at the same time reaches half of the total number of nodes, the probability of the occurrence of failed shards is still less than $10^{-4}$ , and the system still has good survivability.
SCHMIDT GAMES AND CONDITIONS ON RESONANT SETS

Winning sets of Schmidt's game enjoy a remarkable rigidity. Therefore, this game (and modifications of it) have been applied to many examples of complete metric spaces (X;d) to show that the set of 'badly approximable points' Bad(F), with respect to a given familyF of resonant sets inX, is a winning set. For these examples, strategies were deduced that are, in most cases, strongly adapted to the specific underlying setting. We introduce a new modification of Schmidt's game which combines and generalizes the ones of (24) and (27). We then axiomatize conditions on the collection of resonant sets under which we can show Bad(F) to be a winning set for the modification. Moreover, we discuss properties of winning sets of this modification and verify our conditions for several examples - among them, the set Bad r of badly approximable vectors in R n , C 2 and Z 2, intersected with 'nice fractal sets', with weights r and, as a main example, the set of geodesic rays in a proper geodesic CAT(-1) space which avoid a suitable collection of convex subsets.

This way they assist to prevention of chronic diseases, to improvement of living environment as well as to bring economic stimulation. The paper deals with various approaches to evaluation of walkability where tens of various indices are currently recognized. The case study focus on assessment walkability in Ostrava and Hradec Kralove using two mainstream indices with the aim to compare advantages and disadvantages of both approaches in practical applications.
Deformation of complex structures on manifolds with boundary. II. Families of noncoercive boundary value problems

A skate sharpener having a cylindrical sharpening member held between two symmetrical members forming a holder. A radical slot is provided in the holder for receiving a skate blade to be sharpened by the sharpening member. The width of the slot can be varied to snugly receive skate blades of different width. The sharpening member is centrally retained in the holder, relative to the slot, regardless of the width of the slot.
The spherical Paley-Wiener theorem on the complex Grassmann manifolds SU(+)/S(U_{}×U_{})

We prove the Paley-Wiener theorem for the spherical transform on the complex Grassmann manifolds U/K = SU(p + q )/S(U p x U q ). This theorem characterizes the K-biinvariant smooth functions f on the group U that are supported in the K-invariant ball of radius R, with R less than the injectivity radius of U/K, in terms of holomorphic extendability, exponential growth, and Weyl invariance properties of the spherical Fourier transforms f, originally defined on the discrete set A sph of highest restricted spherical weights.
Resonance Fluorescence of a Quantum Dot near a Metallic Nanoparticle: Quantum Interference Effects

: In recent years, significant attention has been given to the quantum or nonlinear optical properties of semiconductor quantum dots coupled to plasmonic nanostructures. A phenomenon that has been studied is the modification of the resonance fluorescence spectrum of the quantum dot by the presence of the plasmonic nanostructure. The most common plasmonic nanostructure that has been studied is the metallic (mainly gold or silver) nanosphere and in most studies the quantum dot is modeled as a two-level quantum system. In this work, we model the quantum dot structure with a three-level V-type quantum system, which can naturally arise in quantum dots, and study the resonance fluorescence spectrum near a metallic nanosphere. We show that the present system leads to quantum interference effects due to the presence of the metallic nanoparticle and specifically due to the anisotropic Purcell effect that occurs in the photon emission of the quantum dot near the metallic nanosphere. We then study the resonance fluorescence spectrum, for different distances between the quantum dot and the metallic nanosphere and show that the resonance fluorescence spectrum changes significantly from a single-peak spectrum to a multipeak spectrum. The effects of quantum interference in the resonance fluorescence spectrum are also explored.
Numerical study of capillary-gravity solitary waves

Two types of small-amplitude capillary-gravity solitary waves are known to exist. One type bifurcates from a uniform flow when the Froude number is equal to 1 and the Weber number larger than 1/3. The other type bifurcates from a train of infinitesimal periodic waves at the minimum of the dispersion curve for all values of the Froude number between 0 (infinite depth) and 1. We investigate numerically the behavior of these waves away from their bifurcation point and show that these two types are globally connected. Moreover new families of capillary-gravity solitary waves of finite amplitude are shown to exist.
La enfermera Genene Jones: El rol de ángel de la muerte en la obra Misery de Stephen King

With the sublime emotional description that Stephen King achieves of the main characters in Misery, the writer manages to delve into the world of affections and feelings, exploring the art of care and its negative aspects. He manages to delve into the figure of the nurse Genene Jones, representative of the role of the angel of death, making visible theories that frame these typologies and their acts. Objective: to describe the behaviours, experiences, beliefs and values set out by Stephen King in the story "Misery" (1987). Methodology: Phenomenological-historical study with an exploratory approach in narrative and secondary sources of the events that took place in the period between 1950-1990. Results: The piece is a masterful analysis of Genene Jones' nursing practice. It also reflects the transformation from the role of an angel of death, carried out by a health professional, to become a serial killer. Conclusion: The study of the horror literature allows the study of the nursing role to deepen and increase the knowledge of the nursing role, both for health professionals and nursing students and the general population.
Group allocation based on peer feedback

ABSTRACT The extraction of individual marks from a group submission is one approach to address the problem of students who don't contribute adequately to group work. This is a highly active research area. An alternative is proposed in this paper: alter the method by which groups are allocated for assessed coursework in tertiary education. The proposed two-step method involves (i) soliciting feedback from the students on the effort invested by their classmates in preliminary assignments and (ii) using these data to allocate groups for a subsequent larger assignment. Students who invest a lot of effort in the preliminary assignments are grouped with similarly motivated students, reducing their dissatisfaction, while students who formerly acted as ‘freeloaders’ are now obliged to engage with the larger assignment and thereby achieve the desired learning outcomes. This paper describes a trial of this group allocation approach for an undergraduate engineering design course of 111 students.

Developing Foreign Bond Markets: The Arirang Bond Experience in Korea

This study investigates the development of Korea's foreign bond (Arirang) market for won-denominated foreign bonds. We provide an institutional perspective and discuss the problems, concerns and key issues related to the development of this market. We find no evidence that Arirang issuance either crowded out local debt or had exchange rate implications. Overall, the Korean experience provides valuable lessons for other emerging nations seeking to build bond markets for local and foreign issuers. Instigating market development demands an enabling infrastructure, the nurturing of local and international demand and the deregulation of capital flows. This process is demanding, as the sophistication of the local bond market does not make it appealing to foreign borrowers per se.
Orexinergic neurons modulate stress coping responses in mice

Stress is a critical precipitating factor for major depression. However, individual responses to the same stressor vary widely, possibly owing to individual variations in stress resilience. Nevertheless, the factors that determine stress susceptibility and resilience remain poorly understood. Orexin neurons have been implicated in the control of stress-induced arousal. Therefore, we investigated whether orexin-expressing neurons are involved in the regulation of stress resilience in male mice. We found that the level of c-fos expression was significantly different in susceptible versus resilient mice in the learned helplessness test (LHT). Furthermore, activating orexinergic neurons induced resilience in the susceptible group, and this resilience was also consistently observed in other behavioral tests. However, activating orexinergic neurons during the induction period (during inescapable stress exposure) did not affect stress resilience in the escape test. In addition, analyses using pathway-specific optic stimulation revealed that activating orexinergic projections to the medial part of the nucleus accumbens (NAc) alone mediated a decrease in anxiety but was not sufficient to induce resilience in the LHT. Collectively, our data suggest that orexinergic projections to multiple targets control diverse and flexible stress-related behaviors in response to various stressors.
The finite size effect on resonance poles

The effect of the finite size of an array of scatterers on the position of the resonance poles of the scattered amplitudes is studied. This effect must be studied because in reality, an infinite array cannot be realized. In particular, it is expected that for a finite array of scatterers, the imaginary parts of the resonance poles (resonance widths) cannot vanish as is the case for an infinite double array admitting bound states in the radiation continuum.
Platelet Lipidome Fingerprint: New Assistance to Characterize Platelet Dysfunction in Obesity

Obesity is associated with a pro-inflammatory and pro-thrombotic state that supports atherosclerosis progression and platelet hyper-reactivity. During the last decade, the platelet lipidome has been considered a treasure trove, as it is a source of biomarkers for preventing and treating different pathologies. The goal of the present study was to determine the lipid profile of platelets from non-diabetic, severely obese patients compared with their age- and sex-matched lean controls. Lipids from washed platelets were isolated and major phospholipids, sphingolipids and neutral lipids were analyzed either by gas chromatography or by liquid chromatography coupled to mass spectrometry. Despite a significant increase in obese patient’s plasma triglycerides, there were no significant differences in the levels of triglycerides in platelets among the two groups. In contrast, total platelet cholesterol was significantly decreased in the obese group. The profiling of phospholipids showed that phosphatidylcholine and phosphatidylethanolamine contents were significantly reduced in platelets from obese patients. On the other hand, no significant differences were found in the sphingomyelin and ceramide levels, although there was also a tendency for reduced levels in the obese group. The outline of the glycerophospholipid and sphingolipid molecular species (fatty-acyl profiles) was similar in the two groups. In summary, these lipidomics data indicate that platelets from obese patients have a unique lipid fingerprint that may guide further studies and provide mechanistic-driven perspectives related to the hyperactivate state of platelets in obesity.
The United Nations After 75: Assessing Current Understandings, Charting Fruitful Research Agendas

From its capacity for deploying joint operations in conflict zones to its status as a standard-bearing forum for international behaviour, the United Nations has asserted its relevance in a diverse array of issues and conflicts around the world. Equally as diverse has been the scholarship surrounding the United Nations over the past several decades. This collection of essays provides a snapshot of these diverse lines of scholarship, highlighting existing scholarship on a range of topics, as well as identifying areas of opportunity for future scholarly work on these topics. Taken as a whole, this forum more broadly provides insight into core pillars of the United Nations' mission--including the maintenance of peace and security; fostering friendly relations between nations; promoting human rights and humanitarian goals; and encouraging cooperation and harmonization of interests between nations. Moving forward, it is our hope that this collection will serve as a sprigboard for inspiring future work to both build and expand upon the insights from the past several decades of scholarship on the United Nations.
