Abstract: Influence of duty ratio of metallic gratings applied in quantum well infrared photodetector (QWIP) with detection ranging from 3 μm to 5 μm was studied in this paper. The influence on longer enhanced wavelength working at infrared waveband was investigated. A relationship between the duty ratio and the enhanced peak intensity is given. Some results can be applied to optimize the enhanced efficiency of the metallic gratings.
An in vivo study with an MRI tracer method reveals the biophysical properties of interstitial fluid in the rat brain
HongBin Han,Kai Li,JunHao Yan,Kai Zhu,Yu Fu

Abstract: The nature of brain interstitial fluid (ISF) has long been a subject of controversy. Most of the previous studies on brain ISF were carried out in vitro. In the present study, a novel method was developed to characterize ISF in the living rat brain by magnetic resonance (MR) imaging using gadolinium-diethylenetriaminepentaacetic acid (Gd-DTPA) as a tracer. Sprague Dawley rats (n=8) were subjected to MR scanning before and after the introduction of Gd-DTPA into the caudate nucleus. A one-way drainage of brain ISF was demonstrated on the dynamic MR images. According to the traditional diffusion model, the diffusion and clearance rate constants of the tracer within brain extracellular space (ECS) were derived as (3.38+ 1.07)×10 4 mm2 s 1 and (7.60±4.18)×10 5 s 1. Both diffusion and bulk flow contributed to the drainage of ISF from the caudate nucleus, which demonstrated an ISF-cerebrospinal fluid confluence in the subarachnoid space at the lateral and ventral surface of the brain cortex at 3 h after the injection. By using this newly developed method, the brain ECS and ISF can be quantitatively measured simultaneously in the living brain, which will enhance the understanding of ISF and improve the efficiency of drug therapy via the brain interstitium.
Myelodysplastic Syndrome with Myelofibrosis Transformed to a Precursor B-Cell Acute Lymphoblastic Leukemia: A Case Report with Review of the Literature
Ayed A. Algarni,Mojtaba Akhtari,Kai Fu
Case Reports in Hematology , 2012, DOI: 10.1155/2012/207537
Abstract: Myelodysplastic syndromes (MDS) comprise a group of heterogeneous clonal hematopoietic cell disorders characterized by cytopenias, bone marrow hypercellularity, and increased risk of transformation to acute leukemias. MDS usually transformed to acute myeloid leukemia, and transformation to acute lymphoblastic leukemia (ALL) is rare. Herein, we report a unique patient who presented with MDS with myelofibrosis. Two months after the initial diagnosis, she progressed to a precursor B-cell acute lymphoblastic leukemia. She was treated with induction therapy followed by allogenic stem cell transplantation. She was alive and doing well upon last followup. We have also reviewed the literature and discussed the clinicopathologic features of 36 MDS patients who progressed to ALL reported in the literature.
The Role of Dicer in DNA Damage Repair
Kai-Fu Tang,Hong Ren
International Journal of Molecular Sciences , 2012, DOI: 10.3390/ijms131216769
Abstract: Dicer is the key component of the RNA interference pathway. Our group and others have reported that knockdown or knockout of Dicer leads to DNA damage in mammalian cells. Two groups recently showed that efficiency of DNA damage repair was greatly reduced in Dicer-deficient cells and that Dicer-dependent small RNAs (~21 nucleotides) produced from the sequences in the vicinity of DNA double-strand break sites were essential for DNA damage repair. Moreover, accumulating data have suggested that miroRNAs play pivotal roles in DNA damage repair. In this review, we discuss the molecular mechanisms by which loss of Dicer leads to DNA damage, as well as the role of Dicer in tumorigenesis.

On Secularization of Western Choral Music
Jie-fu ZHANG,Kai ZHOU
Canadian Social Science , 2008,
Abstract: Although Western choral music was born in the soil of religious culture, it has been in the process of secularization ever since the Middle Ages. Renaissance and the Religion Reformation resulted in a combination of religious chorus and secular chorus and such a combination develops towards a more harmonious and intimate relationship in modern times. This article is to analyze the process and significance of the secularization of western choral music. Key words: chorus, Renaissance, Religion Reformation, secularization Résumé: Bien que née dans un contexte religieux, la musique chorale de l’Occident se situe toujours dans le processus de sécularisation depuis la dernière période du Moyen-Age. Sous l’influence de la Renaissance et de la Réforme religieuse, le choeur religieux et le choeurs profane s’intègrent mutuellement et présente à l’époque contemporaine une tendance de fusion l’un est dans l’autre . Le présent article tente de procéder à une analyse sur la sécularisation de la musique chorale occidentale et sa signifiance. Mots-Clés: choeur, Renaissance, Réforme religieuse, sécularisation

She was alive and doing well upon last followup. We have also reviewed the literature and discussed the clinicopathologic features of 36 MDS patients who progressed to ALL reported in the literature. 1. Introduction Myelodysplastic syndrome (MDS) comprises a group of heterogeneous clonal hematopoietic cell disorders characterized by cytopenias, bone marrow hypercellularity, and increased risk of transformation to acute leukemias; usually to acute myeloid leukemia (in 20–50% of MDS patients). Transformation of MDS to acute lymphoblastic leukemia (ALL) is rare. To date, there are only 35 reported cases of MDS progressed to ALL, to the best of our knowledge. Herein, we report a unique patient who presented with MDS and myelofibrosis and progressed to precursor B-cell acute lymphoblastic leukemia shortly after the initial presentation. 2. Case Report A 53-year-old Caucasian woman with a known history of diabetes mellitus type 2, osteoarthritis, hypertension, and hyperlipidemia presented, after a possible acute upper respiratory tract infection, with shortness of breath, fatigue, nausea, and vomiting. Initial physical examination showed no lymphadenopathy or hepatosplenomegaly. Her CBC revealed pancytopenia with white blood cell (WBC) count = 1.8 × 109/L, hemoglobin = 4.5?g/dL, mean corpuscular volume (MCV) = 84.8?fL, hematocrit = 12.5, and platelet count = 83 × 103/cmm. She underwent a bone marrow aspirate and biopsy. The bone marrow aspiration was unsuccessful. The bone marrow biopsy showed a markedly hypercellular bone marrow at 90% cellularity with panhyperplasia (Figure 1). Mild-to-moderate erythroid dysplasia was present in the form of binucleation, nuclear blebbing and irregular nuclear contours. The megakaryocytes were moderately increased with focal abnormal clustering and occasional dyspoietic forms like nuclear hypolobation and micromegakaryocytes. The myeloid precursors showed abnormal localization in the core biopsy without significant morphological
Recent Advances and Challenges in Ubiquitous Sensing
Stephan Sigg,Kai Kunze,Xiaoming Fu
Computer Science , 2015,
Abstract: Ubiquitous sensing is tightly coupled with activity recognition. This survey reviews recent advances in Ubiquitous sensing and looks ahead on promising future directions. In particular, Ubiquitous sensing crosses new barriers giving us new ways to interact with the environment or to inspect our psyche. Through sensing paradigms that parasitically utilise stimuli from the noise of environmental, third-party pre-installed systems, sensing leaves the boundaries of the personal domain. Compared to previous environmental sensing approaches, these new systems mitigate high installation and placement cost by providing a robustness towards process noise. On the other hand, sensing focuses inward and attempts to capture mental activities such as cognitive load, fatigue or emotion through advances in, for instance, eye-gaze sensing systems or interpretation of body gesture or pose. This survey summarises these developments and discusses current research questions and promising future directions.
