Entangled optical quantum states are essential towards solving questions in fundamental physics and are at the heart of applications in quantum information science. For advancing the research and development of quantum technologies, practical access to the generation and manipulation of photon states carrying significant quantum resources is required. Recently, integrated photonics has become a leading platform for the compact and cost- efficient generation and processing of optical quantum states. Despite significant advances, most on-chip non- classical light sources are still limited to basic bi-photon systems formed by two-dimensional states （i.e., qubits）. An interesting approach beating large potential is the use of the time or frequency domain to enabled the scalable on- chip generation of complex states. In this manuscript, we review recent efforts in using on-chip optical frequency combs for quantum state generation and telecommunica- tions components for their coherent control. In particular, the generation of bi- and multi-photon entangled qubit states has been demonstrated, based on a discrete time domain approach. Moreover, the on-chip generation of high-dimensional entangled states （quDits） has recentlybeen realized, wherein the photons are created in a coherent superposition of multiple pure frequency modes. The time- and frequency-domain states formed with on-chip frequency comb sources were coherently manipulated via off-the-shelf telecommunications compo- nents. Our results suggest that microcavity-based entangled photon states and their coherent control using accessible telecommunication infrastructures can open up new venues for scalable quantum information science.

Premature birth,defined as birth before 37 weeks completed gestation,represents 11.1%of all live births worldwide and the rate has increased in almost all countries over the past few decades(Dhillon et al.,2018).Although mortality after preterm birth has fallen steadily over time,preterm infants continue to have very high rates of neurodevelopmental disability,including severe motor disorders such as cerebral palsy(Dhillon et al.,2018;Yates et al.,2021).

Studies on the behavior of molecular transport properties such as thermal conductivity, gas permeability, volume and surface resistivity have been carried out for the naturally woven coconut sheath （CS） fiber reinforced composites with the addition of nanoclay and chemical treatment of fiber. The compression molding technique was used to fabricate the coconut sheath/clay reinforced hybrid composites. The morphological studies such as X-ray diffractogram （XRD）, transmission electron microscopy （TEM） and scanning electron microscopy （SEM） have been carried out for polyester nanocomposites and coconut sheath fiber. The decreased gas permeability, thermal conductivity and volume and surface resistivity have been observed with increasing the weight percentage of nanoclay in polyester matrix. In chemical modifications, the alkali and silane treated coconut sheath reinforced composites have shown great influence on the transport properties due to the increasing hydrophilic nature by the topographical changes at the fiber surface. Dielectric strength has also been reported in this paper for all types of composites. Infra-red （IR） spectra have also been taken to study the physical and chemical structural changes of treated coconut sheath.

Challenges in developing therapeutic strategies for mild neonatal encephalopathy

引用

Neural Regeneration Research 2022年第2期17卷 277-282页

作者： Alice McDouall Guido Wassink Laura bennet Alistair J.Gunn Joanne O.Davidson Department of Physiology The University of AucklandAucklandNew Zealand

There is increasing evidence that infants with mild neonatal encephalopathy(NE) have significant risks of mortality, brain injury and adverse neurodevelopmental outcomes. In the era of therapeutic hypothermia, infants need to be diagnosed within 6 hours of birth, corresponding with the window of opportunity for treatment of moderate to severe NE, compared to the retrospective grading over 2 to 3 days, typically with imaging and formal electroencephalographic assessment in the pre-hypothermia era. This shift in diagnosis may have increased the apparent prevalence of brain damage and poor neurological outcomes seen in infants with mild NE in the era of hypothermia. Abnormal short term outcomes observed in infants with mild NE include seizures, abnormal neurologic examination at discharge, abnormal brain magnetic resonance imaging and difficulty feeding. At 2 to 3 years of age, mild NE has been associated with an increased risk of autism, language and cognitive deficits. There are no approved treatment strategies for these infants as they were not included in the initial randomized controlled trials for therapeutic hypothermia. However, there is already therapeutic creep, with many centers treating infants with mild NE despite the limited evidence for its safety and efficacy. The optimal duration of treatment and therapeutic window of opportunity for effective treatment need to be specifically established for mild NE as the evolution of injury is likely to be slower, based on preclinical data. Randomized controlled trials of therapeutic hypothermia for infants with mild NE are urgently required to establish the safety and efficacy of treatment. This review will examine the evidence for adverse outcomes after mild NE and dissect some of the challenges in developing therapeutic strategies for mild NE, before analyzing the evidence for therapeutic hypothermia and other strategies for treatment of these infants.

The Arabidopsis Protein CGLD11 Is Required for Chloroplast ATP Synthase Accumulation

ATP synthases in chloroplasts （cpATPase） and mitochondria （mtATPase） are responsible for ATP production during photosynthesis and oxidative phosphorylation, respectively. Both enzymes consist of two multi- subunit complexes, the membrane-bound coupling factor O and the soluble coupling factor 1. During cpATPase biosynthesis, several accessory factors facilitate subunit production and orchestrate complex assembly. Here, we describe a new auxiliary protein in Arabidopsis thaliana, which is required for cpATPase accumulation. AtCGLD11 （CONSERVED IN THE GREEN LINEAGE AND DIATOMS 11） is a protein without any known functional domain and shows dual localization to chloroplasts and mitochondria. Loss of AtCGLDll function results in reduced levels of cpATPase and impaired photosynthetic performance with lower rates of ATP synthesis. In yeast two-hybrid experiments, AtCGLD11 interacts with the 13 subunits of the cpATPase and mtATPase. Our results suggest that AtCGLD11 functions in F1 assembly during cpATPase biogenesis, while its role in mtATPase biosynthesis may not, or not yet, be essential.

Glia and hemichannels: key mediators of perinatal encephalopathy

Neural Regeneration Research 2018年第2期13卷 181-189页

作者： Robert Galinsky Joanne O.Davidson Justin M.Dean Colin R.Green Laura bennet Alistair J.Gunn Department of Physiology University of Auckland The Ritchie Centre Hudson Institute of Medical Research Department of Ophthalmology University of Auckland

Perinatal encephalopathy remains a major cause of disability, such as cerebral palsy. Therapeutic hypo- thermia is now well established to partially reduce risk of disability in late preterm/term infants. However, new and complementary therapeutic targets are needed to further improve outcomes. There is increasing evidence that glia play a key role in neural damage after hypoxia-ischemia and infection/inflammation. In this review, we discuss the role of astrocytic gap junction （connexin） hemichannels in the spread of neural injury after hypoxia-ischemia and/or infection/inflammation. Potential mechanisms of hemichannel medi- ated injury likely involve impaired intraceUular calcium handling, loss of blood-brain barrier integrity and release of adenosine triphosphate （ATP） resulting in over-activation of purinergic receptors. We propose the hypothesis that inflammation-induced opening of connexin hemichannels is a key regulating event that initiates a vicious cycle of excessive ATP release, which in turn propagates activation of purinergic receptors on microglia and astrocytes. This suggests that developing new neuroprotective strategies for preterm infants will benefit from a detailed understanding of glial and connexin hemichannel responses.

Globalization and digitisation have replaced traditional teaching methods gradually over the last 20 years. Teaching is no longer based on textbooks, but more on digital or visual media, such as MP4, TV & movie, and the internet. These irrevocable trends provide students, especially L2 students, more opportunities to learn and cultivate new ideas. Pedagogy alteration in language and literacy education is a positive ideal for helping L2 learners better understanding their classes in a new teaching and learning context.
