In Gao’s previous work, the authors determined several degree conditions of a graph which admits fractional factor in particular settings. It was revealed that these degree conditions are tight if b = f(x) = g(x) = a for all vertices x in G. In this paper, we continue to discuss these degree conditions for admitting fractional factor in the setting that several vertices and edges are removed and there is a difference Δ between g(x) and f(x) for every vertex x in G. These obtained new degree conditions reformulate Gao’s previous conclusions, and show how Δ acts in the results. furthermore,counterexamples are structured to reveal the sharpness of degree conditions in the setting f(x) =g(x) + Δ.

Spinal cord injuries affect nearly five to ten individuals per million every year. Spinal cord injury causes damage to the nerves, muscles, and the tissue surrounding the spinal cord. Depending on the severity, spinal injuries are linked to degeneration of axons and myelin, resulting in neuronal impairment and skeletal muscle weakness and atrophy. The protection of neurons and promotion of myelin regeneration during spinal cord injury is important for recovery of function following spinal cord injury. Current treatments have little to no effect on spinal cord injury and neurogenic muscle loss. Clemastine, an food and Drug Administration-approved antihistamine drug, reduces inflammation, protects cells, promotes remyelination, and preserves myelin integrity. Recent clinical evidence suggests that clemastine can decrease the loss of axons after spinal cord injury, stimulating the differentiation of oligodendrocyte progenitor cells into mature oligodendrocytes that are capable of myelination. While clemastine can aid not only in the remyelination and preservation of myelin sheath integrity, it also protects neurons. However, its role in neurogenic muscle loss remains unclear. This review discusses the pathophysiology of spinal cord injury, and the role of clemastine in the protection of neurons, myelin, and axons as well as attenuation of skeletal muscle loss following spinal cord injury.

Jürgen Ruesch and Gregory Bateson were dedicated to the research paradigm that asserts the successful Axiom of Communication Theory: The Intentionality Code of "You Both Can And Cannot Communicate"(Make up Your Mind and Change Your Mind—You can learn!). Ruesch and Bateson's axiomatic view of Codes critiques the failed Intentionality Messages, i.e., the failed Postulate of Information Theory: The Behavior of "You Cannot Not Communicate" raised to the status of a fetish in the American speech communication discipline by the publication of Paul Watzlawick, Janet Helmick Beavin, and Don J. Jackson, Pragmatics of Human Communication: A Study of Interactional Patterns, Pathologies, and Paradoxes(New York, NY: W. W. Norton & Co., Inc., 1967). Although dedicated "To Gregory Bateson, friend and Mentor", this book(hereafter cited as WBJ) is not co-authored by Bateson and its publication was vigorously opposed by him for many reasons, including the argument of the present analysis that shows a fundamental misunderstanding and gross misapplication of Information Theory(Shannon & Weaver) in place of Communication Theory(Weiner & Bateson) and the mathematical logic(Edmund Husserl & Bertrand Russell) upon which the distinction is based.

American semiotics derives much of its success with applied communication because it is grounded in Peircian logic and rhetoric *** believes human communication is a semiotic relation that we commonly name"creativity".The logic combines Probability(Tychism),Continuity(Synechism),and our capacity to be mistaken(fallibilism).The theory is illustrated by a review of the Peircian logic and its contemporary model used by Michel *** applied aspects are explicated through the methodology models of the architect Buckminster fuller,the business organization consultant William Gordon,and the community organizer Saul *** problematic of"cultural perception"in creativity is addressed using Edmund Husserl and Maurice Merleau-Ponty who suggest how perspective shifts as between East and West.

生鲜乳中的耐热酶会严重影响产品货架期的质量稳定性,而耐热酶的主要来源和污染途径一直存在争论。基于宏基因组技术分析中国某牧场的环境样本(牛舍垫土、TMR饲料)和生鲜乳样本(头三把奶、头三把奶之后生鲜乳、储奶罐中生鲜乳)的微生物群落组成及其产胞外蛋白酶(EC 3.***.24.40)和脂肪酶(EC 3.***.1.3)的基因丰度,弄清储奶罐中生鲜乳的耐热酶污染来源。多样性分析结果表明:牛舍垫土中的典型嗜冷菌丰富度,如假单胞菌属(1.57%)和不动杆菌属(1.56%)远高于其它样品,远高于头三把奶(0.26%,0.54%)。通过微生物产酶基因分析,储奶罐中生鲜乳中产生耐热酶的微生物主要来自嗜冷菌,为假单胞菌属和不动杆菌属。各样本中产蛋白酶的基因丰度为:牛舍垫土:8.71、头三把奶:0.18;产脂肪酶各的基因丰度为:牛舍垫土:16.19、TMR饲料:0.33、头三把奶:0.18、头三把奶之后生鲜乳:0.39、储奶罐中生鲜乳:0.22。此外,储奶罐中生鲜乳的脂肪酶基因在挤奶环节中基因重复率最低为57.14%。因此,微生物及其嗜冷菌通过牛舍垫土污染奶牛乳头,在挤奶环节会进入生鲜乳收集管路而造成污染。本研究为有效防控生鲜乳中耐热酶的污染提供了理论和数据基础。

The corrosion resistance of pure magnesium with surface alloying layer obtained by a solid diffusion alloying technique has been analyzed. To establish the optimum treatment time, the experiments were performed at 480℃ for different solid diffusion time （8, 16, and 24h）. The diffusion interaction effectiveness between Zn, Al mix powder and the sample surface, depending on the treatment time for diffusion at given temperatures, has an obvious influence on corrosion resistance and corrosion mechanism. Corrosion properties were studied using the constant immersion test （in 3.0% NaCl solution, temperature is （28±1）℃, and time is 96h）. Optical microscopy （OM） and EDS （energy dispersive spectrum） composition analysis were used to examine the cross-sectional microstructural characteristics of alloyed layer of treated samples. It is shown that in comparison with the untreated samples, the treated ones possess a better corrosion resistance. The Al5Mg11Zn4 phase, which formed as a continuous phase due to the diffusion of Al, Zn, and Mg elements and subsequent interaction on the outermost layer of diffusion alloying zones （especially the samples treated for 24h at 480℃）, was inert to the chloride solution compared with pure magnesium and acted as a corrosion barrier, and therefore the best corrosion resistance was obtained. This protective action of Al5Mg11Zn4 phase was found to change with its amount, which was controlled by the diffusion time at given temperature. It was concluded that the continuous Al5Mg11Zn4 phase （WP-zone） of the reacted layer in pure magnesium was beneficial from the point of view of corrosion resistance.
