description: Three new transition metal complexes, [Zn(L1)2(OTs)(CH3OH)](TsO)·CH3OH (1), {[Zn(L2)(H2O)4](SiF6)·H2O}n (2) and {[Cd(L2)2(OTs)2]·2DMF}n (3), were prepared from pyridine thiazolone derivatives (where L1 = 2-[4-(2-pyridinyl)-2-thiazolyl]hydrazone, L2 = 2-[4-(3-pyridinyl)-2-thiazolyl]hydrazone) and characterized by 1H-NMR, elemental analysis (EA), and infrared spectra (IR). The crystalline behavior of L1 and 1–3 were analyzed by X-ray diffraction. In the structure of 1, L1 acts as a bidentate agent coordinating the Zn2+ ion through the pyridine nitrogen and thiazole nitrogen, while L2 bonded in a 2D structure by coordinating Zn2+ through the nitrogen atoms of two pyridine rings in the structure of 2. Additionally, with Cd2+ ions as connection points and the spatial extension of L2, 3 possesses an intricate 3D metal–organic framework. The luminescent properties for the ligands and complexes were investigated. The in vitro antimicrobial and antitumor activities were evaluated against ten pathogenic bacterial strains and four human cancer cell lines.

Publisher: name: Contributions to Discrete Mathematics
Year: 2019

description: The feedback vertex number $\tau(G)$ of a graph $G$ is the minimum number of vertices that can be deleted from $G$ such that the resultant graph does not contain a cycle. We show that $\tau(S_p^n)=p^{n-1}(p-2)$ for the Sierpi\'{n}ski graph $S_p^n$ with $p\geq 2$ and $n\geq 1$. The generalized Sierpi\'{n}ski triangle graph $\hat{S_p^n}$ is obtained by contracting all non-clique edges from the Sierpi\'{n}ski graph $S_p^{n+1}$. We prove that $\tau(\hat{S}_3^n)=\frac {3^n+1} 2=\frac{|V(\hat{S}_3^n)|} 3$, and give an upper bound for $\tau(\hat{S}_p^n)$ for the case when $p\geq 4$.

description: Purpose: This study investigates the perspectives of rehabilitation therapists on the implementation of fall prevention programmes with community-dwelling stroke survivors in the Singapore context, and elicits recommendations to adapt the Stepping On programme with stroke survivors. Method: Qualitative data were elicited during 4 focus groups with 23 rehabilitation therapists (15 occupational therapists [OTs]; 8 physiotherapists [PTs]) who had received training to deliver the original Stepping On programme, and had experienced delivery of fall-prevention intervention programmes locally. Collected data were analysed using thematic analysis method. Results: Three themes emerged from the focus groups describing: (a) limitations of existing falls prevention intervention for stroke clients; (b) the need to adapt the Stepping On programme to use with stroke clients; and (c) challenges in implementing fall prevention programmes in the stroke context. A series of new components were suggested to be included as part of the Stepping On after stroke (SOAS) programme, including involvement of family members and caregivers, and tailored community reintegration sessions (such as taking public transport and shopping). Conclusions: Rehabilitation therapists describe challenges in addressing fall prevention within a stroke context, and findings highlight the need for a structured, stroke-specific fall prevention programme rather than a more general approach to education and training. Contextual components identified provide valuable inputs towards the development of a culturally relevant fall prevention programme for stroke survivors in Singapore.Implications for RehabilitationStroke survivors living in the community are at a high risk of falls.A structured and culturally relevant fall prevention programme for community-living stroke survivors is needed.Falls prevention for community-living stroke survivors should be multi-dimensional and targeting the modifiable risk factors for falls in this group.Both stroke survivors and caregivers should be involved in any fall prevention after stroke programmes. Stroke survivors living in the community are at a high risk of falls. A structured and culturally relevant fall prevention programme for community-living stroke survivors is needed. Falls prevention for community-living stroke survivors should be multi-dimensional and targeting the modifiable risk factors for falls in this group.

Publisher: name: Contributions to Discrete Mathematics
Year: 2019

description: We prove that 3-connected plane triangulations containing a single edge contained in all separating triangles are hamiltonian-connected. As a direct corollary we have that 3-connected plane triangulations with at most one separating triangle are hamiltonian-connected. In order to show bounds on the strongest form of this theorem, we proved that for any s >= 4 there are 3-connected triangulation with s separating triangles that are not hamiltonian-connected. We also present computational results which show that all `small' 3-connected triangulations with at most 3 separating triangles are hamiltonian-connected.

In this paper, we investigate septuple $(a_1,a_2,a_3,a_4,a_5,a_6,a_7)\in \mathbb{N}^5\times \mathbb{Q}^2$ for which $\sum_{a_1k+a_2 \ {\rm square}}p(a_3a_4^\alpha n+a_6 a_4^\alpha+a_7-k) \equiv 1\ ({\rm mod}\ 2)$ if and only if $a_5n+1$ is a square. We prove some new parity results of sums of partitions and squares in arithmetic progressions which are analogous to the results due to Ballantine and Merca.

description: Soil salinization significantly restricts crop yield, animal foraging, and biomass production for biofuels. Identifying an efficient farming system to mitigate these concerns has become a major research focus. The present study addresses the potential of rotating triticale and sweet sorghum at various planting densities to alleviate soil salt stress, enhance production, improve agronomic characteristics, and boost soil microbial communities in a saline agricultural environment in East China. Several indicators in 2017 and 2018. Results show that triticale and sweet sorghum planting significantly decreased soil salt contents compared to bare land plots. Multiple agronomic traits were measured for each planting density. For triticale, a density of 180 × 104 plants ha−1 showed the best plant height, tiller number per plant, yield, and lodging rate; for sweet sorghum, a density of 7 × 104 plants/ha showed the best plant height, yield, and lodging rate. High-density planting of triticale (180, 260, 320 × 104 plants/ha) and sweet sorghum (7, 8, 9 × 104 plants/ha) was associated with high counts of bacteria, Actinomycetes, and salt-tolerant Actinomycetes. However, planting density had no significant effect on the counts of fungi or salt-tolerant bacteria. Redundancy Discriminant Analysis (RDA) showed that plant height, yield, lodging rate, bacteria, salt-tolerant bacteria, Actinomycetes, and salt-tolerant Actinomycetes were negatively correlated with soil salinity, while tiller number per plant and stem thickness were positively correlated with soil salinity. In conclusion, a rotation system of triticale and sweet sorghum with planting densities of 180 × 104 and 7 × 104 plants/ha, respectively was established to improve and make full use of saline soil.

On 2-adic behavior of the number of domino tilings on torus

Publisher: name: Contributions to Discrete Mathematics
Year: 2019

description: We study the 2-adic behavior of the number of domino tilings of a $2(2n+1)\times 2(2n+1)$ torus. We show that this number is of the form $2^{4n+3}g(n)^2+2^{8n+2}(2n+1)^{4n}h(n)$, where $g(n)$ and $h(n)$ are odd positive integers. Moreover, we prove that $g(n)$ and $h(n)$ are uniformly continuous under the 2-adic metric and invariant under interchanging $n$ and $-1-n$. This paper is an analogy of Henry Cohn's results for $2n\times 2n$ squares (Electron. J. Combin. 6 (1999)).

Sun toughness and $P_{\geq3}$-factors in graphs
Creators: name: Zhou, Sizhong
Publisher: name: Contributions to Discrete Mathematics
Year: 2019

description: A $P_{\geq n}$-factor means a path factor with each component having at least $n$ vertices, where $n\geq2$ is an integer. A graph $G$ is called a $P_{\geq n}$-factor deleted graph if $G-e$ admits a $P_{\geq n}$-factor for any $e\in E(G)$. A graph $G$ is called a $P_{\geq n}$-factor covered graph if $G$ admits a $P_{\geq n}$-factor containing $e$ for each $e\in E(G)$. In this paper, we first introduce a new parameter, i.e., sun toughness, which is denoted by $s(G)$. $s(G)$ is defined as follows: $$ s(G)=\min\{\frac{|X|}{sun(G-X)}: X\subseteq V(G), \ sun(G-X)\geq2\} $$ if $G$ is not a complete graph, and $s(G)=+\infty$ if $G$ is a complete graph, where $sun(G-X)$ denotes the number of sun components of $G-X$. Then we obtain two sun toughness conditions for a graph to be a $P_{\geq n}$-factor deleted graph or a $P_{\geq n}$-factor covered graph. Furthermore, it is shown that our results are sharp.

description: The nuclear recoil effect on the $g$ factor of H- and Li-like heavy ions is evaluated to all orders in $αZ$. The calculations include an approximate treatment of the nuclear size and the electron-electron interaction corrections to the recoil effect. As the result, the second largest contribution to the theoretical uncertainty of the $g$-factor values of $^{208}$Pb$^{79+}$ and $^{238}$U$^{89+}$ is strongly reduced. Special attention is paid to tests of the QED recoil effect on the $g$ factor in experiments with heavy ions. It is found that, while the QED recoil effect on the $g$-factor value is masked by the uncertainties of the nuclear size and nuclear polarization contributions, it can be probed on a few-percent level in the specific difference of the $g$ factors of H- and Li-like heavy ions. This provides a unique opportunity to test QED in a new region --- strong-coupling regime beyond the Furry picture.

Quantum States of Topologically Massive Electrodynamics and Gravity

description: The free quantum states of topologically massive electrodynamics and gravity in 2+1 dimensions, are explicitly found. It is shown that in both theories the states are described by infrared-regular polarization tensors containing a regularization phase which depends on the spin. This is done by explicitly realizing the quantum algebra on a functional Hilbert space and by finding the Wightman function to define the scalar product on such a Hilbert space. The physical properties of the states are analyzed defining creation and annihilation operators. For both theories, a canonical and covariant quantization procedure is developed. The higher order derivatives in the gravitational lagrangian are treated by means of a preliminary Dirac procedure. The closure of the Poincaré algebra is guaranteed by the infrared-finiteness of the states which is related to the spin of the excitations through the regularization phase. Such a phase may have interesting physical consequences.

description: We investigate spatial variations of turbulent properties in the Small Magellanic Cloud (SMC) by using neutral hydrogen HI observations. With the goal of testing the importance of stellar feedback on HI turbulence, we define central and outer SMC regions based on the star formation rate (SFR) surface density, as well as the HI integrated intensity. We use the structure function and the Velocity Channel Analysis (VCA) to calculate the power-law index (gamma) for both underlying density and velocity fields in these regions. In all cases, our results show essentially no difference in gamma between the central and outer regions. This suggests that HI turbulent properties are surprisingly homogeneous across the SMC when probed at a resolution of 30 pc. Contrary to recent suggestions from numerical simulations, we do not find a significant change in gamma due to stellar feedback as traced by the SFR surface density. This could be due to the stellar feedback being widespread over the whole of the SMC, but more likely due to a large-scale gravitational driving of turbulence. We show that the lack of difference between central and outer SMC regions can not be explained by the high optical depth HI.

description: AeP-P-2, a pectic polysaccharide, was extracted from the fruit pod of okra. It composed of rhamnose (Rha), arabinose (Ara), glucose (Glc), galactose (Gal) and galacturonic acid (GalA) with the ratio of 4.75:2.01:1.00:4.91:7.24. The main structural feature of AeP-P-2 are 1,4-linked galacturonan units (homogalacturonan backbone) and (1 → 2) and (1 → 2,4) linked Rha (rhamnogalacturonan I region). And the other side chains contained →1)-linked Ara, (1 → 5)-linked Ara, (1 → 4)-linked Glc, (1 → 6)-linked Gal, (1 → 4)-linked Rha, (1 → 2,4)-linked Rha, →1)-linked Ara and →1)-linked Gal. When the concentration of AeP-P-2 was 3.2 mg/mL, the scavenging rates on DPPH·, ABTS, O2−· and ·OH reached to 61.88%, 87.10%, 52.17% and 60.32%, respectively. AeP-P-2 also could protect PC12 cells from the damage of H2O2 and reduce apoptosis caused by oxidative damage by decreasing the level of ROS. The findings indicated that okra was a functional vegetable and AeP-P-2 was worth studying and developing into antioxidant component.

description: This paper presents an exploratory study of college-age students using two-way, push-to-talk cellular radios. We describe the observed and reported use of cellular radio by the participants. We discuss how the half-duplex, lightweight cellular radio communication was associated with reduced interactional commitment, which meant the cellular radios could be used for a wide range of conversation styles. One such style, intermittent conversation, is characterized by response delays. Intermittent conversation is surprising in an audio medium, since it is typically associated with textual media such as instant messaging. We present design implications of our findings.

description: The dynamics of a large array of coupled semiconductor lasers is studied for a nonlocal coupling scheme. Our focus is on chimera states, a self-organized spatio-temporal pattern of co-existing coherence and incoherence. In laser systems, such states have been previously found for global and nearest-neighbor coupling, mainly in small networks. The technological advantage of large arrays has motivated us to study a system of 200 nonlocally coupled lasers with respect to the emerging collective dynamics. The crucial parameters are the coupling strength, the coupling phase and the range of the nonlocal interaction. We find that chimera states with multiple (in)coherent domains exist in a wide region of the parameter space. We provide quantitative characterization for the obtained chimeras and other spatio-temporal patterns.

description: In this paper, we obtain a blow-up result for solutions to a semi-linear wave equation with scale-invariant dissipation and mass and power non-linearity, in the case in which the model has a "wave like" behavior. In order to achieve this goal, we perform a change of variables that transforms our starting equation in a strictly hyperbolic semi-linear wave equation with time-dependent speed of propagation. Then, we apply Kato's lemma to find a blow-up result for solutions to the transformed equation under some support and sign assumptions on the initial data. A special emphasis is placed on the limit case, that is, when the exponent p is exactly equal to the upper bound of the range of admissible values of p for which this blow-up result is valid. In this critical case an explicit integral representation formula for solutions of the corresponding linear Cauchy problem in 1d is derived. Finally, carrying out the inverse change of variables we get a non-existence result for global (in time) solutions to the original model.

description: To investigate the influence of reactive oxygen species (ROS) on the secondary metabolites of the marine-derived fungus Dichotomomyces cejpii F31-1, hydrogen peroxide (H2O2) was added to the GPY culture medium. The HPLC chromatogram of the EtOAc extract of the culture broth was distinct from that of the H2O2 free GPY medium. Further study of the metabolites in the GPY medium with H2O2 resulted in the discovery of eight known compounds. Among them, (22E)-5α, 8α-epidioxyergosta-6, 22-dien-3β-ol (2) and ergosta-4,6,8(14),22-tetraene-3-one (3) were present in the highest concentration, while ergosterol and diketopiperazines are abundant in the H2O2 free medium. Additionally, a new compound, dichocetide D (1) containing a chlorine element and a known ergosterol (10) were isolated from the H2O2 free medium. (22E)-5α, 8α-epidioxyergosta-6, 22-dien-3β-ol (2) exhibited moderate cytotoxic activity against human prostate cancer cell line LNCaP-C4-2B.

description: Purpose: This meta-analysis aimed to determine the diagnostic performance of neutrophil gelatinase-associated lipocalin (NGAL) in diabetic nephropathy (DN). Methods: We searched the PubMed, Embase, Wanfang, and China National Knowledge Infrastructure databases for articles published up to 24 April 2019. The meta-analyses were conducted by Stata 11.0, and diagnostic accuracy, sensitivity, specificity, negative and positive likelihood ratios (NLR and PLR), diagnostic odds ratio (DOR), and receiver operating characteristic (ROC) curve data were pooled. Moreover, heterogeneity and small trials bias were evaluated. Results: Six cross-sectional studies were included in the meta-analysis. For the studies of microalbuminuria versus normoalbuminuria, the estimates (95% confidence interval) were as follows: sensitivity, 0.75 (0.51–0.89); specificity, 0.78 (0.70–0.84); PLR, 3.37 (2.49–4.56); NLR, 0.33 (0.16–0.69); DOR, 10.31 (4.05–26.25); and area under the ROC curve (AUC), 0.81 (0.77–0.84). For the studies of microalbuminuria + macroalbuminuria versus normoalbuminuria, the results were as follows: sensitivity, 0.83 (0.66–0.93); specificity, 0.88 (0.67–0.97); PLR, 7.20 (1.97–26.31); NLR, 0.19 (0.08–0.46); DOR, 37.83 (4.84–295.65); AUC, 0.92 (0.90–0.94). Deeks’ funnel plot suggested that small trials bias was insignificant in this study. Conclusions: Our findings suggest that NGAL is a potential diagnostic marker for patients with DN and that its diagnostic value for microalbuminuria + macroalbuminuria is superior to that for microalbuminuria.HighlightsThe first meta-analysis to investigate NGAL diagnostic role in DN.NGAL is valuable for the early diagnosis of DN.The diagnostic value of NGAL in microalbuminuria + macroalbuminuria was much higher. The first meta-analysis to investigate NGAL diagnostic role in DN. NGAL is valuable for the early diagnosis of DN. The diagnostic value of NGAL in microalbuminuria + macroalbuminuria was much higher.

description: This qualitative case study investigated high school students’ perceptions of career and technical education (CTE) programs, focusing on factors that impact their college and career readiness. The evolution of CTE from traditional vocational training to a comprehensive educational approach reflects the changing demands of today’s workforce, where success requires technical, academic, and employability skills. As states adopt CTE as a viable graduation pathway, particularly in Indiana, understanding student experiences in these programs becomes crucial. Through interviews with senior CTE concentrators at an urban high school, the study explored students’ motivations for persisting in CTE pathways, their awareness of available resources, and the perceived value of credentials, dual credits, and work-based learning. Using social cognitive career theory (SCCT) and Bandura’s (1977) self-efficacy theory as a framework, the research examined how students’ self-efficacy and career aspirations have been shaped by their CTE experiences. Findings highlighted strengths and gaps in CTE programs, providing insights for improving program quality and alignment with industry needs. Ultimately, this study contributed to a more equitable and responsive CTE framework, ensuring all students, regardless of background, have access to opportunities that prepare them for meaningful postsecondary pathways and workforce success. Insights from this study may inform educators, policymakers, and industry leaders on how to enhance CTE pathways to support a diverse, well-prepared workforce, and address historical inequities in educational access and career readiness.

description: In this work we employ the Fourier Transform Raman Spectroscopy to study normal and tumoral human breast tissues, including several subtypes of cancers. We analyzed 194 Raman spectra from breast tissues that were separated into 9 groups according to their corresponding histopathological diagnosis. The assignment of the relevant Raman bands enabled us to connect the several kinds of breast tissues (normal and pathological) to their corresponding biochemical moieties alterations and distinguish among 7 groups: normal breast, fibrocystic condition, duct carcinoma-in-situ, duct carcinoma-in-situ with necrosis, infiltrating duct carcinoma not otherwise specified, colloid infiltrating duct carcinoma and invasive lobular carcinomas. We were able to establish the biochemical basis for each spectrum, relating the observed peaks to specific biomolecules that play special role in the carcinogenesis process. This work is very useful for the premature optical diagnosis of a broad range of breast pathologies. We noticed that we were not able to differentiate inflammatory and medullary duct carcinomas from infiltrating duct carcinoma not otherwise specified.

description: Изучение ряда произведений и обстоятельств идейно-литературного развития В. В. Розанова, еще не получивших должного научного внимания, может способствовать обновлению сложившихся представлений о творческом феномене выдающегося русского писателя и мыслителя. Анализируя в свете подобной целевой установки книгу путевых очерков и статей В. В. Розанова «Итальянские впечатления» (1909), рассматривая этот текст в контексте текущих литературно-критических оценок и характерных для конца 1900-х годов умонастроений самого автора, мы приходим к выводу об этапном значении произведения. В функциональном отношении оно фактически открывает итоговый период розановского творчества и объективно несет на себе массу его отличительных примет и противоречий. Главной проблемой для В. В. Розанова на рубеже первого и второго десятилетий ХХ века становится необходимость интеграции прежних (по сути, уже исчерпавших себя и утративших импульс саморазвития) идей религиозно-модернистского качества в новый идеологический и мировоззренческий формат, ассоциированный с русским национально-консервативным сознанием. Опыт непосредственной реализации подобной инициативы, немаловажной частью которого становятся «Итальянские впечатления», наглядно продемонстрировал, что в распоряжении Розанова не оказалось необходимого ресурса для осуществления задуманного, и иначе как формальным образом разрешить поставленную задачу было невозможно. Это обстоятельство вывело на поверхность слабые места в розановской системе взглядов, обнажило ряд противоречий и коллизий авторского самосознания, предопределило как минимум скептическую, а по большей части резко негативную реакцию современников писателя на предложенный российской общественности проект «нового Розанова». Таким образом, исследование ориентирует научную мысль на комплексный анализ проблем творчества В. В. Розанова 1910-х годов без абсолютизации художественных достижений данного периода; ситуативно, помимо прочего, подчеркивается гносеологическое значение дореволюционных источников.
Currency and commodity metabolites: Their identification and relation to the modularity of metabolic networks

description: The large-scale shape and function of metabolic networks are intriguing topics of systems biology. Such networks are on one hand commonly regarded as modular (i.e. built by a number of relatively independent subsystems), but on the other hand they are robust in a way not expected of a purely modular system. To address this question we carefully discuss the partition of metabolic networks into subnetworks. The practice of preprocessing such networks by removing the most abundant substrates, "currency metabolites," is formalized into a network-based algorithm. We study partitions for metabolic networks of many organisms and find cores of currency metabolites and modular peripheries of what we call "commodity metabolites." The networks are found to be more modular than random networks but far from perfectly divisible into modules. We argue that cross-modular edges are the key for the robustness of metabolism.

description: В статье рассмотрены особенности индивидуального стиля Л. Н. Толстого в аспекте теории «эмблематического реализма» Р. Густафсона на примере повести «Отец Сергий» и рассказа «Хозяин и работник». Субъективное осознание Толстым своей миссии пророка приводит к изменению коммуникативных установок писателя в 1880-1890-х гг. Показано, что эмблематические образы в предельно сжатом виде выражают суть размышлений Толстого об истинной жизни, а эмблематическая поэтика позволяет писателю расширять повествовательное пространство. Архетипические образы, которые являются вариациями на тему основного сюжетного события, получают в повести «Отец Сергий» подчёркнуто эмблематическое звучание. Рассказ «Хозяин и работник» содержит широкий диапазон глубинных смыслов. В контексте позднего творчества писателя категория «хозяин и работник» приобретает эмблематическое звучание. Понятие «хозяин» в значении «человек, владеющий чем-либо» преобразуется Толстым и переносится из области обыденного существования в область метафизическую, связанную с высшей божественной силой. Хозяин – не человек, а Бог. Понятие «работник» Толстой связывает с общехристианской традицией, заключающейся в том, что каждый человек исполняет волю Бога на земле: Бог – Хозяин, человек – работник. Эмблематическая история о грехе и спасении в повести «Отец Сергий» приобретает жанровые признаки притчи. Эмблематические образы в предельно сжатом виде выражают квинтэссенцию размышлений Толстого об истинной жизни. Таким образом, понятие «эмблематический реализм» оказывается концептуально значимым для определения художественного метода Толстого. Эмблематическая поэтика позволяла писателю расширять повествовательное пространство и придавать ему духовное измерение.

description: The first step in statistical reliability studies of coherent systems is the estimation of the reliability of each system component. For the cases of parallel and series systems the literature is abundant. It seems that the present paper is the first that presents the general case of component inferences in coherent systems. The failure time model considered here is the three-parameter Weibull distribution. Furthermore, neither independence nor identically distributed failure times are required restrictions. The proposed model is general in the sense that it can be used for any coherent system, from the simplest to the more complex structures. It can be considered for all kinds of censored data; including interval-censored data. An important property obtained for the Weibull model is the fact that the posterior distributions are proper, even for non-informative priors. Using several simulations, the excellent performance of the model is illustrated. As a real example, boys first use of marijuana is considered to show the efficiency of the solution even when censored data occurs.
