Group-Blind Multiuser Detectors for CDMA : Synchronous Systems

ABSTRACT We consider the problem of multiuser detection for CDMA (code division multiple access) systems where the codes of some users are known while others are unknown, group-blind multiuser detection. An example is at the base station of a cellular communication system with interference from both in-cell users, with known codes, and out-of-cell users, with unknown codes. In this paper we develop a number of group-blind multiuser detectors using a subspace approach. One class of detectors developed has a computationally efficient structure of a subspace estimation common to all known users, followed by a simple processing specific to each user. The performance of the detectors is compared to that of the purely blind detector and the non-blind detector, and the group-blind detectors are seen to have the best performance.
The complete mitochondrial genome of the Huang Lang chicken

Abstract Huang Lang chicken is the native breed of Hunan province in China. The complete mitochondrial (mt) genome sequence plays an important role in the accurate determination of phylogenetic relationships among metazoans. It is the first time that the complete mt genome sequence of the Huang Lang chicken was reported in this work, which was determined through the polymerase chain reaction-based method. The total length of the mitogenome is 16,786 bp, with the base composition of 30.25% for A, 23.71% for T, 32.53% for C and 13.51% for G, in the order C > A > T > G feature occurs in the Huang Lang chicken. It contains the typical structure, including two ribosomal RNA genes, 13 protein-coding genes, 22 transfer RNA genes and 1 non-coding control region (D-loop region). The complete mt genome sequence of the Huang Lang chicken provided an important data for further study on the genetic mechanism.

Introduction:implicit and explicit learning of languages

Implicit learning, essentially the process of acquiring unconscious (implicit) knowledge, i s a fundamental feature of human cognition (Cleeremans, Destrebecqz, & Boyer, 1998; Diene s, 2012; Perruchet, 2008; Shanks, 2005; Reber, 1993) . Many complex behaviors , including language comprehension and production (Berry & Dienes, 1993; Winter & Reber, 1994) , music cognition (Rohrmeier & Rebuschat, 2012), intuitive decision making (Plessner, Betsch, & Betsch, 2008), and social interaction (Lewicki, 1986), are thought o be largely dependent on implicit knowledge. The term implicit learning was first used by Arthur Reber (1967) to describe a process during which subjects acquire knowledge about a complex, rule -governed stimulus environment without intending to and without becoming aware of the knowledge they have acquired. In contrast, the term explicit learning refers to a process during which participants acquire conscious (explicit) knowledge; this is generally ass oci ted with intentional learning conditions, e.g., when participants are instructed to look for rules or patterns. In his seminal study, Reber (1967) exposed subjects to letter sequences (e.g., TPTS, VXXVPS and TPTXXVS) by means of a memorization task. In experiment 1, subjects were presented with letter sequences and simply asked to commit them to memory . One group of subjects was given sequences that were generated by means of a finite -state grammar (Chomsky, 1956, 1957; Chomsky & Miller, 1958), while the other group received randomly
Community structure in the U.S. House of Representatives.

Much of the work involved in making United States law is performed by Congressional committees and subcommittees before bills reach the floors of the Senate and House of Representatives. Committee memberships can be viewed as a social network, and the relationships between legislators appointed to common committees can be grouped into various hierarchical levels: individuals, subcommittees, standing and select committees, groups of committees, and the entire floor. Community detection methods from network theory have been successful not only at replicating this hierarchical organization but also at uncovering additional structural features of committee networks. One example, illustrated here for the 108th House 2003-2004 , is the strong overlap between certain committees, such as the Rules Committee and the Select Committee on Homeland Security shown, respectively, in yellow and maroon near the nine o’clock position of the left figure . To study the 108th House’s community structure, we begin with a bipartite network in which the two types of nodes are Representatives and sub committees, with edges representing the assignment of a Representative to a sub committee. We then compute a one-mode projection onto the committees, with edges between committees indicating common Representatives depicted graphically on the upper right, with nodes colored by parent committee and edges shaded according to connection strength . Edges are weighted according to normalized interlock, the ratio of the number of common Representatives between two sub committees to that expected if sub committees of the same sizes had randomly assigned memberships. Different community-detection algorithms can be used to construct trees or “dendrograms” like that shown in the left figure again colored by parent committee . The dashed dividing ring indicates a partition with a high “modularity”: the set of communities at this level of organization is depicted in the lower right figure, in which each community is a node divided in pie-chart fashion according to its committee composition . The weights of the edges indicated using line thickness and shading represent the connection strength between the different communities. Studies like these indicate that network theory can be of substantial use in uncovering collaborative structure in political bodies such as the U.S. Congress, without requiring input in the form of political opinions or judgments by the researcher.
Bilateral Asymmetry in Chinese Families with Cleft Lip with or without Cleft Palate

Objective To determine if Chinese individuals with nonsyndromic cleft lip with or without cleft palate (CL/P) display more bilateral asymmetry than do their unaffected relatives. Design/Subjects A case-control study of 313 individuals with CL/P from Shanghai, China, with 201 unaffected relatives as controls. Methods Size-adjusted asymmetry scores were defined by data on middle-finger length, palm length, palpebral fissure width, and ear length. Case-control comparisons used a multivariate repeated measures analysis of variance, paired t tests, and the Wilcoxon signed rank test. Results The ear-length measure showed a significant increase in fluctuating asymmetry (FA) in individuals with CL/P compared with their unaffected relatives, which was most pronounced in the female cleft lip and palate subgroup (p = .04). No other measures showed any increase in FA. Conclusion Evidence was found for increased FA, as measured by overall ear length, in Chinese individuals with nonsyndromic CL/P, compared with their unaffected family members. The use of bilateral measurements other than dermatoglyphics may prove to be a valuable means of assessing overall developmental stability in individuals with developmental malformations and in their families.
High-Rate, Gas-Phase Growth of MoS2 Nested Inorganic Fullerenes and Nanotubes

The gas-phase reaction between MoO3-x and H2S in a reducing atmosphere at elevated temperatures (800� to 950�C) has been used to synthesize large quantities of an almost pure nested inorganic fullerene (IF) phase of MoS2. A uniform IF phase with a relatively narrow size distribution was obtained. The synthesis of IFs appears to require, in addition to careful control over the growth conditions, a specific turbulent flow regime. The x-ray spectra of the different samples show that, as the average size of the IF decreases, the van der Waals gap along the c axis increases, largely because of the strain involved in folding of the lamella. Large quantities of quite uniform nanotubes were obtained under modified preparation conditions.
Reappraisal of C‐reactive protein as a screening tool for neonatal sepsis

Aims: To assess the usefulness of C‐reactive protein (CRP) [either alone or in combination with a full blood examination (FBE) and microbiology of gastric aspirate] in predicting the diagnosis of neonatal sepsis compared with routinely available markers of infection. Methods: A prospective study of quantitative CRP, FBE, gastric aspirate and surface swab microscopy and culture in predicting neonatal sepsis in a level III perinatal referral hospital was performed. Results: Of 301 episodes evaluated over a 5‐month period, there was a 5% rate of major (culture proven) sepsis (3% early onset, <72 hours) and 10% rate of modified sepsis. No single test alone was sufficiently reliable as an indicator of infection to be a satisfactory screening tool for early onset sepsis [CRP sensitivity 67%, negative predictive value (NPV) 86%, FBE sensitivity 63%, NPV 80%, gastric aspirate sensitivity 57%, NPV 83%]. Conclusion: The three‐test combination had a sensitivity of 97%, NPV 98% and likelihood ratio of 49, thus providing a useful diagnostic tool.
Fluorine-18-fluorodeoxyglucose-guided breast cancer surgery with a positron-sensitive probe: validation in preclinical studies.

UNLABELLED In this study, the feasibility of utilizing 2-deoxy-2-fluoro-d-glucose (FDG) in conjunction with a positron-sensitive intraoperative probe to guide breast tumor excision was investigated. METHODS The probe was constructed with a plastic scintillator tip coupled to a photomultiplier tube with fiber optic cable. Anticipated resolution degradation was evaluated by measurement of line spread functions in the presence of background radiation. Realistic photon background distributions were simulated with a human torso phantom and a cardiac insert. The relationship between resolution and energy threshold was measured to find the optimal discriminator settings. In addition, probe sensitivity as a function of energy threshold was determined for various size-simulated tumors. Finally, the ability to localize breast cancers in vivo was tested in a rodent model. Mammary rat tumors implanted in Lewis rats were examined after injection with FDG; these results were correlated with those of histologic analyses. RESULTS Measurements of line spread functions indicated that resolution could be maximized in a realistic background photon environment by increasing the energy threshold to levels at or above the Compton continuum edge (340 keV). At this setting, the probe's sensitivity was determined to be 58 and 11 cps/muCi for 3.18- and 6.35-mm diameter simulated tumors, respectively. Probe readings correlated well with histologic results: the probe was generally able to discriminate between tumor and normal tissue. CONCLUSION This study indicates that breast cancer surgery guided by a positron-sensitive probe warrants future evaluation in breast-conserving surgery of patients with breast cancer.
Unraveling the WRKY transcription factors network in Arabidopsis Thaliana by integrative approach

The WRKY transcription factors superfamily are involved in diverse biological processes in plants including response to biotic and abiotic stresses and plant immunity. Protein-protein interaction network is a useful approach for understanding these complex processes. The availability of Arabidopsis Thaliana interactome offers a good opportunity to do get a global view of protein network. In this work, we have constructed the WRKY transcription factor network by combining different sources of evidence and we characterized its topological features using computational tools. We found that WRKY network is a hub-based network involving multifunctional proteins denoted as hubs such as WRKY 70, WRKY40, WRKY 53, WRKY 60, WRKY 33 and WRKY 51. Functional annotation showed seven functional modules particularly involved in biotic stress and defense responses. Furthermore, the gene ontology and pathway enrichment analysis revealed that WRKY proteins are mainly involved in plant-pathogen interaction pathways and their functions are directly related to the stress response and immune system process.
Transferring Knowledge to Smaller Network with Class-Distance Loss

Training a network with small capacity that can perform as well as a larger capacity network is an important problem that needs to be solved in real life applications which require fast inference time and small memory requirement. Previous approaches that transfer knowledge from a bigger network to a smaller network show little benefit when applied to state-of-the-art convolutional neural network architectures such as Residual Network trained with batch normalization. We propose class-distance loss that helps teacher networks to form densely clustered vector space to make it easy for the student network to learn from it. We show that a small network with half the size of the original network trained with the proposed strategy can perform close to the original network on CIFAR-10 dataset.
A novel single-stage full-bridge buck-boost inverter

A novel single-stage full-bridge series-resonant buck-boost inverter (FB-SRBBI) is proposed in this paper. The proposed inverter only includes a full-bridge topology and a LC resonant tank without auxiliary switches. The output voltage of the proposed inverter can be larger or lower than the dc input voltage, depending on the instantaneous duty-cycle. This property is not found in the classical voltage source inverter, which produces an ac output instantaneous voltage always lower than the dc input voltage. The proposed inverter circuit topology provides the main switch for turn-on at ZCS by a resonant tank. The nonlinear control strategy is designed against the input dc perturbation and achieves well dynamic regulation. An average approach is employed to analyze the system. A design example of 500 W dc/ac inverter is examined to assess the inverter performance and it provides high power efficiency above 90% under the rated power.
Repair of base-base mismatches in simian and human cells.

Mismatched heteroduplexes arise as intermediates of several dissimilar genetic processes. The outcome of these genetic events will therefore be influenced by the efficiency and specificity of mismatch repair. We have studied the correction of base-base mispairs in simian and human fibroblasts by transfecting the cells with derivatives of SV40 DNA, each harboring a single mispair in a defined orientation. Analysis of plaques revealed that correction efficiencies for homomispairs followed the pattern G.G greater than C.C greater than or equal to A.A greater than T.T. Repair bias was influenced by flanking sequences. Correction efficiences for heteromispairs followed the pattern of G.T greater than A.C greater than C.T greater than A.G and repair favored the retention of G + C by a substantial margin. This repair specificity could lead to a gene conversion bias favoring the accumulation of G + C in sequences subject to high levels of recombination or unequal exchange.
A double‐blind comparison of codeine and morphine for postoperative analgesia following intracranial surgery

Codeine and morphine were compared in a double‐blind study of postoperative analgesia in 40 patients after intracranial neurosurgery. Eighteen patients received codeine phosphate 60 mg and 18 morphine sulphate 10 mg, both by intramuscular injection; 4 patients (10%) required no analgesia. Both drugs provided analgesia within 20 min of injection but morphine was more effective than codeine beyond 60 min (p = 0.01). Fewer doses of morphine than codeine were required (p = 0.003). Nine patients requested one dose of morphine and 9 two doses. Seven patients required three doses of codeine and 1 patient required four doses. Neither drug caused respiratory depression, sedation, pupillary constriction or unwanted cardiovascular effects. We conclude that, in the doses used, morphine is a safe alternative to codeine for analgesia after neurosurgery and has a more persistent action.
Anti‐angiogenic therapy subsequent to adeno‐associated‐virus‐mediated immunotherapy eradicates lymphomas that disseminate to the liver

Liver cancer has a very poor prognosis and lacks effective therapy. We have previously demonstrated that intraportal injection of adeno‐associated‐viral (AAV) particles that express angiostatin lead to long‐term expression of angiostatin capable of suppressing the outgrowth of EL‐4 tumors in the liver. Here we combine AAV‐mediated angiostatin therapy with immunotherapy by employing an AAV vector encoding the T‐cell costimulator B7.1. Incubation of EL‐4 cells with AAV‐B7.1 viruses resulted in the rapid expression of B7.1 on the surface of 80% of EL‐4 cells. Mice that were vaccinated with B7.1‐engineered tumor cells rejected the tumor cells and resisted a secondary challenge with unmodified parental cells. Splenocytes from the vaccinated mice were highly cytotoxic towards parental EL‐4 cells in vitro. However, the vaccinated mice failed to resist the challenge of a heavy burden of EL‐4 cells. Intraportal injection of AAV particles that express angiostatin into mice that had been vaccinated 1 month earlier with B7.1‐engineered tumor cells protected mice against the challenge of a heavy burden of EL‐4 cells and eradicated tumors that had disseminated to the liver. The combinational therapy increased the survival rate of mice with advanced liver cancer. These encouraging results warrant investigation of the employment of anti‐angiogenic therapy subsequent to cancer immunotherapy for targeting unresectable disseminated liver metastases.
PROTOTYPE WAVEFORM INTERPOLATION FOR ECG COMPRESSION

This paper describes a prototype waveform interpolation approach for efficient electrocardiogram (ECG) compression. The algorithm is based on the interpolation of discrete cosine transform coefficients of the prototypes extracted from the linear predictive residuals of ECG frames. The proposed algorithm therefore exploits the inter-cycle and intra-cycle redundancies that are present in ECG signal. The results reveal that linear predictive based prototype waveform interpolation is suitable for ECG compression and unquantized prototypes provided percentage root mean square difference (PRD) values below 10%.
Evolutionary lineages of RT1.Ba in the Australian Rattus.

In this study, the evolutionary history of the variable second exon of RT1.Ba and its adjoining intron b are compared across a number of species and subspecies of the Australian RATTUS: Three lineages are identified in the second intron across a range of Rattus species. Two of these lineages, separated by the insertion of a probable rodent short interspersed nucleotide element and by point mutations outside the indel region, are both found in each of the major clades of the endemic Australian RATTUS: This pattern of ancestral polymorphism is reflected in the adjoining exon 2 sequences, although phylogenetic constraints confirm that the clustering is not identical to that of the associated intron sequences. In addition, the coding sequences show evidence of the retention of ancestral polymorphism, with identical exon sequences found in two divergent species, and some indication of gene conversion detected for the exon sequences.
Interaction of amrinone with endogenous adenosine in guinea‐pig atria

1 In spontaneously beating atria from reserpine‐treated guinea‐pigs, amrinone (10 μm to 2 mm) induced a positive inotropic and chronotropic effect that was preceded by a transient reduction in contractile force and in frequency. Both the positive and negative effects were concentration‐dependent. 2 The inotropic action of amrinone was antagonized by low concentrations of 8‐phenyltheophylline that compete with adenosine at R‐receptors on plasma membrane without significantly influencing phosphodiesterase activity. 3 Cumulative concentrations of amrinone (1 mm) antagonized the reduction of rate of contraction and amplitude induced by dipyridamole 1 μm in spontaneously beating atria and restored the maximum contractile effect reached in the absence of dipyridamole. 4 In spontaneously beating preparations incubated in the presence of adenosine deaminase (1u ml−1), amrinone lost its positive effects on the atria and only reduction of rate and contractile force was evident. Both effects were antagonized by scopolamine 1 mm thus indicating their cholinergic nature. 5 Adenosine at 0.1 μm and 0.5 μm significantly inhibited the inotropic effect induced by amrinone (0.03 to 3 mm) and the concentration‐effect curves of amrinone obtained in the absence and presence of adenosine clearly indicate a competitive antagonism between the two drugs. Thus the contractile activity of amrinone in spontaneously beating atria from reserpine‐treated guinea‐pigs originates from a displacement of adenosine from its R‐receptor sites in the cardiac cell.
WRR support in Linux Block Layer

There is need of differentiated I/O service when applications with diverse performance-needs share a storagedevice. NVMe specification provides a method called Weighted-Round-Robin-with-urgent-priority (WRR) which can help in providing such differentiated I/O service. In Round-Robin arbitration all I/O queues are treated to be of equal priority, leading to symmetric I/O processing. While in WRR arbitration, queues can be marked urgent, high, medium or low, with provision for different weightage for each category. Onus is on host to associate priority with I/O queues and define weights. We find that very little has been done in current Linux ecosystem when it comes to supporting WRR and making benefits reach to application. In this paper we propose a method that introduces WRR support in Linux NVMe driver. This method delivers WRR capability to applications without the need of rebuilding them. Unlike affinity-based approach, it does not limit computeability of application. Our results demonstrate that modified driver indeed provides differentiated I/O performance among applications. Proposed work modifies only NVMe driver and is generic enough to be included in mainstream Linux kernel for supporting WRR.
Family of multiport bidirectional DC¿DC converters

Multiport DC-DC converters are of potential interest in applications such as generation systems utilising multiple sustainable energy sources. A family of multiport bidirectional DC-DC converters derived from a general topology is presented. The topology shows a combination of DC-link and magnetic coupling. This structure makes use of both methods to interconnect multiple sources without the penalty of extra conversion or additional switches. The resulting converters have the advantage of being simple in topology and have a minimum number of power devices. The proposed general topology and basic cells show several possibilities to construct a multiport converter for particular applications and provide a solution to integrate diverse sources owing to their flexibility in structure. The system features a minimal number of conversion steps, low cost and compact packaging. In addition, the control and power management of the converter by a single digital processor is possible. The centralised control eliminates complicated communication structures that would be necessary in the conventional structure based on separate conversion stages. A control strategy based on classical control theory is proposed, showing a multiple PID-loop structure. The general topology and a set of three-port embodiments are detailed.
