The microstructures of cryogenically ball-milled Cu were investigated by high-resolution electron microscopy. It was found that the grain-size reduction is a dislocation-controlled continuous process which consists of the formation of small-angle grain boundaries , a gradual increase in misorientations as a result of accumulation of more dislocations and, finally, the formation of large-angle GBs. The GBs were generally curved, wavy or faceted, and heavily strained, which are typical characteristics of nanostructured materials. In addition, extrinsic dislocations were found in many GBs, (...) indicating that most are in a high-energy non-equilibrium configuration, which is consistent with observations in equal-channel angular pressing processed Cu, Ni, and Al-Mg, repetitive corrugation and straightening processed Cu and room-temperature ball-milled Cu. These results support a still-disputed concept that GBs in nanostructured metals processed by severe plastic deformation are mostly in non-equilibrium states. (shrink)

Jian Zhou,* Weiqiang Ju,* Xiaopeng Yuan, Xiaofeng Zhu, Dongping Wang, Xiaoshun HeOrgan Transplant Center, First Affiliated Hospital, Sun Yat-sen University, Guangzhou, People's Republic of China *These authors contributed equally to this work: Hyperosmolar nonketotic hyperglycemic coma is a serious, rare complication induced by methylprednisolone pulse therapy for acute rejection after orthotopic liver transplantation. Herein, we report an unusual case of a 58-year-old woman who experienced acute rejection at 30 months after OLT, only one case in which HNKHC resulted in MP (...) pulse therapy for acute rejection in all 913 recipients in our center. The general morbidity of HNKHC was 1.09‰ in this study. HNKHC is characterized by rapid onset, rapid progression, and a lack of specific clinical manifestations. High-dose MP management was a clear risk factor. The principle of treatment included rapid rehydration, low-dose insulin infusion, and correcting disorders of electrolytes and acidosis. In conclusion, clinicians considering MP pulse therapy after OLT should be alert to the occurrence of HNKHC. Keywords: liver transplantation, complications, hyperosmolar nonketotic hyperglycemic coma, methylprednisolone pulse therapy, principle of treatment. (shrink)

A part of relativistic dynamics is axiomatized by simple and purely geometrical axioms formulated within first-order logic. A geometrical proof of the formula connecting relativistic and rest masses of bodies is presented, leading up to a geometric explanation of Einstein's famous E = mc² . The connection of our geometrical axioms and the usual axioms on the conservation of mass, momentum and four-momentum is also investigated.

Injury to the central or peripheral nervous system is often associated with persistent pain. After ischemic injury to the spinal cord, rats develop severe mechanical allodynia-like symptoms, expressed as a pain-like response to innocuous stimuli. In its short-lasting phase the allodynia can be relieved with the [gamma]-aminobutyric acid (GABA)-B receptor agonist baclofen, which also reverses the hyperexcitability of dorsal horn interneurons to mechanical stimuli. Furthermore, there is a reduction in GABA immunoreactivity in the dorsal horn of allodynic rats. Clinical neuropathic (...) pain of peripheral and central origin often cannot be relieved by opiates at doses that do not cause side effects. The loss of sensitivity to opiates may be associated with the up-regulation of endogenous antiopioid substances, such as the neuropeptide cholecystokinin (CCK). CCK and its receptor (CCK-R) protein is normally not detectable in rat dorsal root ganglion cells. After peripheral nerve section, both CCK and CCK-R are up-regulated in the dorsal root ganglia. Furthermore, CI 988, an antagonist of the CCK-B receptor, chronically coadministered with morphine, reduces autotomy, a behavior that may be a sign of neuropathic pain following peripheral nerve section. Thus, opiate insensitivity may be due to the release of CCK from injured primary afferents. Similarly, in the chronic phase of the spinal ischemic model of central pain, the allodynia-like symptom is not relieved by systemic morphine, but is significantly reversed by the CCK-B antagonist. Consequently, up-regulation of CCK and CCK-R in the CNS may also underlie opiate drug insensitivity following CNS injury. Thus, dysfunction of central inhibition involving GABA and endogenous opioids may be a factor underlying the development of sensory abnormalities and/or pain following injury to neural tissue.

The fault prediction and abductive fault diagnosis of three-phase induction motors are of great importance for improving their working safety, reliability, and economy; however, it is difficult to succeed in solving these issues. This paper proposes a fault analysis method of motors based on modified fuzzy reasoning spiking neural P systems with real numbers for fault prediction and abductive fault diagnosis. To achieve this goal, fault fuzzy production rules of three-phase induction motors are first proposed. Then, the rMFRSNPS is presented (...) to model the rules, which provides an intuitive way for modelling the motors. Moreover, to realize the parallel data computing and information reasoning in the fault prediction and diagnosis process, three reasoning algorithms for the rMFRSNPS are proposed: the pulse value reasoning algorithm, the forward fault prediction reasoning algorithm, and the backward abductive fault diagnosis reasoning algorithm. Finally, some case studies are given, in order to verify the feasibility and effectiveness of the proposed method. (shrink)

Some Trouble with Cows b.Mahasweta Devi and the Literary Exposure of Violence V.The Question of a Christian Perspective on the Hindu Treatment of Violence and Religion: Are Victims Necessary? Some Presuppositions: • The following reflections, complex as they are, are governed by a reluctance to simplify Hindu teaching. I seek to avoid the view that the Hindu traditions had only one view of violence and nonviolence. • I use the term "Hindu" loosely and as a shorthand, without claiming that there is a single Hindu tradition, or a single creed shared by all Hindus, or a single attitude toward violence. But neither do I claim that there are simply many traditions without any common elements which justify the appellation "Hindu." • I am reluctant to idealize the Hindu traditions as if nonviolence must necessarily be taken as the epitome ofHindu thought. India's traditions are complex, and require complex treatment. • A serious artificiality of this paper is that I treat Hinduism without simultaneously lookinginto Buddhist andJain materials, though both were traditions with important and enduring commitments to nonviolence. Particularly with respect to the renunciant, marginal components of traditions, one ought not to make overly neat or decisive distinctions Violence and Nonviolence in Hindu Religious Traditions 1 1 1 between the Hindu, Buddhist, and Jain theories and practices related to violence and nonviolence. • I attempt to give preference to indigenous discussions ofissues related to violence and nonviolence; the context and mode of thinking are important, notjust the conclusions drawn. I therefore avoid simply mining Hindu texts for an answer to a contemporary question, "What is the Hindu attitude toward violence and nonviolence?" • In most ofwhat follows we must distinguish contexts where "violence" indicates "physical action which causes pain to some living being," from contexts where "violence" indicates "an intention, rooted in anger or malice, to hurt someone." I use the word "violence" for both in order to highlight the complex issues of distinction involved. In considering the Sanskrit formulations, one likewise has to distinguish himsa as "causing pain" from himsa as "intending to harm." • It is often difficult to date ancient texts, and even when one narrows down a date—within 200-300 years—its significance still depends on other, often equally broadly stated dates. Nevertheless, I do offer dates throughout, as summarized here: •ancient Vedic sacrificial practices, from before 1200 BCE •Vedic ritual analyses and reformulations of sacrifices as ritualized acts, in the Brahmanas, from after 1000 BCE •the Upanishadic exploration of the deeper meanings of ritual and interiorized alternatives to ritual, from after 900 BCE •the Buddha, c. 500 BCE •key texts in the theorization of royal power, The Laws of Manu (beginning of Common Era) and Arthashastra (c. 150 CE) •the Tamil wisdom text Tirukkural (100 CE) •Goddess texts as evidenced in Sanskrit formulations, from after 500 CE...

There are good reasons for envisioning a global discourse about God, premised necessarily agreed upon perfections considered to be by definition proper to God, and for thinking through the implications of our understanding of God for morality. Philosophically, it makes sense to hold that claims about omnipotence, omniscience, and other superlative perfections are indeed maximal, and define “God” wherever the terminology of divine persons is taken up. Religiously too, it makes sense to assert that a deity possessed of perfections is (...) not just the deity of one’s own tribe or religion, but also the deity of the whole world, whether acknowledged as such or not. This essay delves into the larger set of rich complexities by three moves. First, I look into a single extended historical case of the extension of the discourse about God beyond the Christian West, the discourse on God proffered by Western Jesuit missionaries in India from the sixteenth to twentieth centuries. Second, I place next to that Jesuit learning the instance of a famed Hindu theologian’s discourse on God, God’s perfections, and their moral implications. Third, I briefly step back and assess the dangers and fruitful prospects inherent in thinking about God and morality in an interreligious context. (shrink)

Psychiatry is rapidly adopting digital phenotyping and artificial intelligence/machine learning tools to study mental illness based on tracking participants’ locations, online activity, phone and text message usage, heart rate, sleep, physical activity, and more. Existing ethical frameworks for return of individual research results (IRRs) are inadequate to guide researchers for when, if, and how to return this unprecedented number of potentially sensitive results about each participant’s real-world behavior. To address this gap, we convened an interdisciplinary expert working group, supported by (...) a National Institute of Mental Health grant. Building on established guidelines and the emerging norm of returning results in participant-centered research, we present a novel framework specific to the ethical, legal, and social implications of returning IRRs in digital phenotyping research. Our framework offers researchers, clinicians, and Institutional Review Boards (IRBs) urgently needed guidance, and the principles developed here in the context of psychiatry will be readily adaptable to other therapeutic areas.

The present study explored the role of emotion regulation and emotion lability/negativity as a moderator in the relation between child social avoidance and social adjustment in Chinese culture. Participants were N = 194 children recruited from nine classrooms in two public kindergartens in Shanghai, People’s Republic of China. Multi-source assessments were employed with mothers rating children’s social avoidance and teachers rating children’s emotion regulation, emotion lability/negativity and social adjustment outcomes. The results indicated that the relations between social avoidance and social (...) adjustment difficulties were more negative among children lower in emotion regulation, but not significant for children with higher emotion regulation. In contrast, the relations between social avoidance and social adjustment difficulties were more positive among children higher in emotion lability/negativity, but not significant for children with lower emotion lability/negativity. This study informs us about how emotion regulation and emotion lability/negativity are jointly associated with socially avoidant children’s development. As well, the findings highlight the importance of considering the meaning and implication of social avoidance in Chinese culture. (shrink)

When fcc single crystals with high-symmetry crystal orientations are deformed to moderate strains by rolling, tension or channel die compression, long dislocation boundaries inclined to the extension axis form. Similarly, long dislocation boundaries are often found in grains embedded in polycrystals deformed in the same manner. These extended planar boundaries are characteristically - 30-40° from the extension direction and contain the transverse specimen axis. The objective of the present article is to demonstrate that EPBs formed during plane strain deformation are (...) parallel to equivalent slip planes, a pair of hypothetical slip systems used for analyses of the strain and crystal rotation components in place of the larger number of physical slip systems. The coincidence of EPBs and equivalent slip plane inclinations is shown to account for persistent observations of EPBs in the angle range - 30-40° from the rolling direction, in rolled single crystals of various initial orientations. The tendency of EPBs towards tilt or twist boundary character can also be rationalized on the basis of the equivalent slip system concept and consideration of the dislocation types available to be incorporated into EPBs.
