Low-complexity signal detection using CG method for uplink large-scale MIMO systems

Large-scale multiple-input multiple-output (LS-MIMO) is considered as a promising key technology for future 5G wireless communications due to its very high spectrum and energy efficiency. However, one challenging problem to achieve these benefits is a practical signal detection algorithm in the uplink. In this paper, we propose a low-complexity near-optimal signal detection algorithm using the conjugate gradient (CG) method for uplink multi-user large-scale MIMO systems, which can avoid the complicated matrix inversion required by linear minimum mean square error (MMSE) signal detection algorithm. We also provide the convergence proof of the proposed scheme to guarantee its usability in practice. The analysis indicates that the proposed scheme can reduce the computational complexity by about one order of magnitude. The simulation results of the bit error rate performance verify that the proposed algorithm outperforms the recently proposed Neumann series approximation algorithm, and achieves the near-optimal performance of the classical MMSE algorithm by using only a small number of iterations.
Beliefs and Attitudes to Bowel Cancer Screening in Patients with CKD: A Semistructured Interview Study.

BACKGROUND AND OBJECTIVES Bowel cancer is a leading cause of cancer-related death in people with CKD. Shared decision making regarding cancer screening is particularly complex in CKD and requires an understanding of patients' values and priorities, which remain largely unknown. Our study aimed to describe the beliefs and attitudes to bowel cancer screening in patients with CKD. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Face to face, semistructured interviews were conducted from April of 2014 to December of 2015 with 38 participants ages 39-78 years old with CKD stages 3-5, on dialysis, or transplant recipients from four renal units in Australia and New Zealand. Thematic analysis was used to analyze the transcripts. RESULTS Five themes were identified: invisibility of cancer (unspoken stigma, ambiguity of risk, and absence of symptomatic prompting); prioritizing kidney disease (preserving the chance of transplantation, over-riding attention to kidney disease, protecting graft survival, and showing loyalty to the donor); preventing the crisis of cancer (evading severe consequences and cognizant of susceptibility); cognitive resistance (reluctance to perform a repulsive procedure, intensifying disease burden threshold, anxiety of a positive test, and accepting the inevitable); and pragmatic accessibility (negligible financial effect, convenience, and protecting anonymity). CONCLUSIONS Patients with CKD understand the potential health benefits of bowel cancer screening, but they are primarily committed to their kidney health. Their decisions regarding screening revolve around their present health needs, priorities, and concerns. Explicit consideration of the potential practical and psychosocial burdens that bowel cancer screening may impose on patients in addition to kidney disease and current treatment is suggested to minimize decisional conflict and improve patient satisfaction and health care outcomes in CKD.
Eighteenth-Century French Musical Theatre

One of the methodological challenges for eighteenth-century French studies is the reconstruction of a literary culture which, while seemingly so familiar to a modern reader, nevertheless combined objects that our own disciplinary and institutional culture casts asunder. However overused the term ‘interdisciplinarity’ may be, the phenomenon was so much a part of the early modern cultural landscape that any narrow literary study of the canonical authors of the period risks obscuring and falsifying that landscape by excluding whatever material, according to our own criteria, looks marginal or minor, despite the influence of that material in its own period. Charles Collé spoke for many when he asked rhetorically, ‘Quelle importance peut-on attacher à des chansons? ’ Yet, as scholars have shown in recent decades, song was so integral to eighteenth-century French culture that theatre in which speech and music were mixed threatened to outstrip regular theatre and through-composed opera in terms of public approval; Bricaire de La Dixmérie famously defended the Théâtre de l’Opéra-Comique by calling on the Opéra to ‘légitimer un bâtard devenu plus riche que lui’. Gustave Attinger stated trenchantly in 1950 that the site of genuine theatrical experimentation in the eighteenth century was the Foires and the Comédie-Italienne. Although the legitimation Dixmérie called for has been slow to arrive, renewed interest has been shown in the variety of theatrical practice that developed during the eighteenth century; it seems appropriate, therefore, to take stock, not least because of the different institutional contexts in which this work continues to be carried out, and because the very diversity of forms concerned defies easy definition and generalization. My discussion will focus on the field of spoken theatre incorporating musical elements, whether sung, instrumental, or incidental. This in itself constitutes a huge range of material, from Beaumarchais’s and Marivaux’s comedies, which, like most of their contemporaries’ works, included terminal songs (divertissements and vaudevilles), through the various types of opéra-comique that proliferated, to the late eighteenth-century mélodrame of Pixérécourt and others, which combined spoken drama and instrumental music. I shall not consider ‘through-composed’ opera with recitative, which is too broad a field and more suited to review in musicological journals; nor shall I discuss the comédie-ballet, which, though a spoken
Walking With Meaning

Physical activity is beneficial for people with dementia, but little research explores subjective experiences of physical activity in this population. Interpretive description guided the analysis of 26 interviews conducted with 12 people with dementia. Three themes described the subjective meaning of everyday physical activity: Participants were attracted to activity because it improved physical well-being, provided social connections, gave opportunity to be in nature, and provided structure and focus; participants experienced impediments to activity because of physical discomfort, environmental factors, lack of enthusiasm, and memory loss; and participants made adjustments by choosing walking over other activities and by being active with others. Results show that physical activity remains important for people with dementia, although they encounter barriers. They may prefer walking with others as a form of activity. Findings could influence how nurses conceptualize wandering and suggest that walking programs could be well received by people with dementia.
Expression and regulation of mouse SERDIN1, a highly conserved cardiac‐specific leucine‐rich repeat protein

Despite recent progress, the precise mechanisms responsible for vertebrate cardiac development are still enigmatic. Better understanding of cardiac biology and disease necessitates identification and analysis of a full spectrum of regulatory and structural proteins specific to the developing heart. By performing an in silico screen, we identified a cardiac‐specific gene we named Serdin1. The Serdin1 gene is conserved, and the message is restricted to the heart in several vertebrate species, thus implicating Serdin1 as an important gene in cardiac development. In situ hybridization confirmed that the Serdin1 message is cardiac‐specific in mice as early as embryonic day 8.5. Antibody staining demonstrated predominantly nuclear staining in immortalized cardiac cell lines (P19 and HL‐1) and proliferating cultured cardiomyocytes, whereas in vivo SERDIN1 localizes to I bands of the sarcomere. Seven kilobases of the upstream regulatory sequence of Serdin1 is sufficient for cardiac‐specific expression. Computer analysis revealed an 80‐bp homologous region between the mouse and the human Serdin genes that contains GATA, SRF, and MEF sites. Cardiac specificity and localization patterns suggest that SERDIN1 is intimately integrated with the molecular pathways controlling cardiogenesis in vertebrates.

A Robust MPC for Input-Output LPV Models

In this note, a discrete-time robust model predictive control (MPC) design approach is proposed to control systems described by linear parameter-varying models in input-output form subject to constraints. To ensure the stability of the closed-loop system, a quadratic terminal cost along with an ellipsoidal terminal constraint are included in the control optimization problem. The MPC design problem is formulated as a linear matrix inequality problem. The proposed MPC scheme is applied on a continuously stirred tank reactor as an illustrative example.
Stigma Annotation Scheme and Stigmatized Language Detection in Health-Care Discussions on Social Media

Much research has been done within the social sciences on the interpretation and influence of stigma on human behaviour and health, which result in out-of-group exclusion, distancing, cognitive separation, status loss, discrimination, in-group pressure, and often lead to disengagement, non-adherence to treatment plan, and prescriptions by the doctor. However, little work has been conducted on computational identification of stigma in general and in social media discourse in particular. In this paper, we develop the annotation scheme and improve the annotation process for stigma identification, which can be applied to other health-care domains. The data from pro-vaccination and anti-vaccination discussion groups are annotated by trained annotators who have professional background in social science and health-care studies, therefore the group can be considered experts on the subject in comparison to non-expert crowd. Amazon MTurk annotators is another group of annotator with no knowledge on their education background, they are initially treated as non-expert crowd on the subject matter of stigma. We analyze the annotations with visualisation techniques, features from LIWC (Linguistic Inquiry and Word Count) list and make prediction based on bi-grams with traditional and deep learning models. Data augmentation method and application of CNN show high performance accuracy in comparison to other models. Success of the rigorous annotation process on identifying stigma is reconfirmed by achieving high prediction rate with CNN.
Realizing Malmö ’ s Neighborhood Functionality and Social Capital Potential The Impacts of High-Speed Transport Infrastructure on Rosengård and Fosie

Increasingly, urban and suburban areas in many western cities are shaped by the tides of high-speed flows of people and goods. While an integral piece of our socio-economic fabric high-speed transport infrastructure (HSTI), limited in this paper to urban road networks, facilitates high-speed vehicle movement at the expense of neighborhood social interaction. A largely mono-functional land use, HSTI occupies large amounts of land dedicated to movement space and spreads out housing, recreational areas, commercial space, and other land uses. The wider space between residential, commercial, and recreational areas increases the distance and time residents must move, which can reduce overall formal and informal socializing among neighbors as well as limit neighborhood functionality. In addition, HSTI imposes "wall" and zone-of-influence effects over neighborhood interactive social exchange space (ISES). While ISES facilitates social exchange and interaction among neighborhood residents and businesses, HSTI increases safety concerns and limits the use and effectiveness of this multi-functional space. By imposing its various effects and reducing the liveliness and continuity of ISES, HSTI limits the development of neighborhood, and especially "bridging" social capital. Interactive social exchange space, especially for lower-income groups, is an important building block of "bonding" and "bridging" social capital. This thesis presents a case study of Rosengård and Fosie, two large neighborhood areas in Malmö, Sweden that are interwoven with HSTI and have indicators of social capital decline. While there are many factors that contribute to Rosengård’s and Fosie’s socio-economic conditions, this paper will present theoretical and empirical evidence that HSTI disrupts and to some extent degrades their neighborhood functionality and stocks of social capital. Through use of traffic calming and creative transport initiatives, Malmö Stad and these neighborhoods may mitigate the negative impacts of HSTI by transforming HSTI from mono-functional movement corridors to a layered social and movement space.
AIA-BDE: A Corpus of FAQs in Portuguese and their Variations

We present AIA-BDE, a corpus of 380 domain-oriented FAQs in Portuguese and their variations, i.e., paraphrases or entailed questions, created manually, by humans, or automatically, with Google Translate. Its aims to be used as a benchmark for FAQ retrieval and automatic question-answering, but may be useful in other contexts, such as the development of task-oriented dialogue systems, or models for natural language inference in an interrogative context. We also report on two experiments. Matching variations with their original questions was not trivial with a set of unsupervised baselines, especially for manually created variations. Besides high performances obtained with ELMo and BERT embeddings, an Information Retrieval system was surprisingly competitive when considering only the first hit. In the second experiment, text classifiers were trained with the original questions, and tested when assigning each variation to one of three possible sources, or assigning them as out-of-domain. Here, the difference between manual and automatic variations was not so significant.
The Connection between the Text and Images of News Articles: New Insights for Multimedia Analysis

We report on a case study of text and images that reveals the inadequacy of simplistic assumptions about their connection and interplay. The context of our work is a larger effort to create automatic systems that can extract event information from online news articles about flooding disasters. We carry out a manual analysis of 1000 articles containing a keyword related to flooding. The analysis reveals that the articles in our data set cluster into seven categories related to different topical aspects of flooding, and that the images accompanying the articles cluster into five categories related to the content they depict. The results demonstrate that flood-related news articles do not consistently report on a single, currently unfolding flooding event and we should also not assume that a flood-related image will directly relate to a flooding-event described in the corresponding article. In particular, spatiotemporal distance is important. We validate the manual analysis with an automatic classifier demonstrating the technical feasibility of multimedia analysis approaches that admit more realistic relationships between text and images. In sum, our case study confirms that closer attention to the connection between text and images has the potential to improve the collection of multimodal information from news articles.
Identification and characterization of KLK14, a novel kallikrein serine protease gene located on human chromosome 19q13.4 and expressed in prostate and skeletal muscle.

The kallikreins are a subfamily of serine proteases encoded in human, mouse, and rat by highly conserved tightly clustered multigene families. Here we report the identification and characterization of KLK14, a novel kallikrein gene located within the human kallikrein locus at 19q13.4. KLK14 is approximately 5.4 kb in length spanning seven exons and, by Northern blot analysis, transcribes two alternative transcripts present only in prostate (1.5 kb) and skeletal muscle (1.9 kb). The protein product, K14, predicted to be a 251-amino-acid secreted serine protease with trypsin-like substrate specificity, is translated in vitro with a molecular mass of approximately 31 kDa. In situ hybridization revealed that, in prostate, KLK14 is expressed by both benign and malignant glandular epithelial cells, thus exhibiting an expression pattern similar to that of two other prostatic kallikreins, KLK2 and KLK3, which encode K2 and prostate-specific antigen, respectively.
Resveratrol sensitizes androgen independent prostate cancer cells to death‐receptor mediated apoptosis through multiple mechanisms

A critical factor in prostate cancer development and progression is the altered expression of apoptotic regulatory proteins which renders cells resistant to both hormone‐ and chemo‐therapies. Resveratrol, a dietary component with chemopreventive properties has been reported to resensitize a variety of cancer cell types to apoptosis. In the current study, the ability of resveratrol pre‐treatment to sensitize hormone refractory prostate cancer cell lines (PC‐3 and DU145) to apoptosis and the mechanisms involved were investigated.
Syntax and Semantics in a Treebank for Esperanto

In this paper we describe and evaluate syntactic and semantic aspects of Arbobanko, a treebank for the artificial language Esperanto, as well as tools and methods used in the production of the treebank. In addition to classical morphosyntax and dependency structure, the treebank was enriched with a lexical-semantic layer covering named entities, a semantic type ontology for nouns and adjectives and a framenet-inspired semantic classification of verbs. For an under-resourced language, the quality of automatic syntactic and semantic pre-annotation is of obvious importance, and by evaluating the underlying parser and the coverage of its semantic ontologies, we try to answer the question whether the language’s extremely regular morphology and transparent semantic affixes translate into a more regular syntax and higher parsing accuracy. On the linguistic side, the treebank allows us to address and quantify typological issues such as the question of word order, auxiliary constructions, lexical transparency and semantic type ambiguity in Esperanto.
Caffeine: Psychological effects, use and abuse.

Caffeine, probably the most widely used drug, affects the psychological state of those who consume it. Abuse results in symptoms of caffeinism which include agitation, disorientation and a syndrome which may be mistaken for anxiety/neurosis. It is a habit forming drug in which tolerance develops. It affects sleep in a dose related manner which is dependent on the daily caffeine intake, i.e., high users have less effect. Its central nervous system stimulation can cause pleasant effects with improved attention and concentration at lower doses. At high doses, the reverse may occur. Used judiciously, it may be a useful therapy in the treatment of hyperkinetic children. These and other effects of caffeine are discussed in this review article.
Recent advances in therapeutics and drug delivery for the treatment of inner ear diseases: a patent review (2011-2015)

ABSTRACT Introduction: Inner ear disorders such as hearing loss, tinnitus, and Ménière’s disease significantly impact the quality of life of affected individuals. Treatment of such disorders is an ongoing challenge. Current clinical approaches relieve symptoms but do not fully restore hearing, and the search for more effective therapeutic methods represents an area of urgent current interest. Areas covered: Thirty four patents and patent applications published from 2011 to 2015 were selected from the database of the U.S. Patent and Trademark Office (USPTO) and World Intellectual Property Organization (WIPO), covering new approaches for the treatment of inner ear disorders described in the patent literature: 1) identification of new therapeutic agents, 2) development of sustained release formulations, and 3) medical devices that facilitate delivery of such agents to the inner ear. Expert opinion: The search for effective treatments of inner ear disorders is ongoing. Increased understanding of the molecular mechanisms of hearing loss, Ménière’s disease, and tinnitus is driving development of new therapeutic agents. However, delivery of these agents to the inner ear is a continuing challenge. At present, combination of a suitable drug with an appropriate mode of drug delivery is the key focus of innovative research to cure inner ear disorders.
[Acute kidney failure caused by Hantaviruses].

Hantavirus-induced acute renal failure is a worldwide occurring disease and rarely known and diagnosed in Germany and in Western Europe. Its various clinical features are embraced by the term Hemorrhagic Fever With Renal Syndrome (HFRS). Cardinal symptoms of the mild European form called Nephropathia epidemica (NE) leading to diagnosis are: abrupt onset, fever, pain (abdominal, loin-, or headache), acute renal failure, proteinuria and/or hematuria, polyuria, and thrombocytopenia. Etiologic agent of NE is the vole transmitted Puumula-serotype of Hantaviruses. Severe courses of HFRS characterized by hemorrhagic complications occur in Asia and Southeast Europe and are caused by the serotypes Hantaan (Korean Hemorrhagic Fever), Seoul (rat associated) and Belgrade (both Epidemic Hemorrhagic Fever). Serological evidence of IgG and/or IgM-antibodies by indirect immunofluorescent antibody assay (IFA), enzyme linked immunosorbent assay (ELISA) or mu-capture-ELISA proves the diagnosis and allows distinction of the infecting virus type. Transmission occurs primarily through inhalation of virus contaminated aerosols or dust. Transmission between humans has never been observed. The incubation period ranges between four days to four weeks. All persons who have much outdoor activities in forests, open fields, farms, and nearby waters are at risk to be infected. Practical exposure prophylaxis seems rarely possible. Therapy of NE is only symptomatic, confined to the treatment of pain, diuretic therapy in oliguric patients, and volume and electrolyte substitution in volume depleted or polyuric patients. Sometimes temporary hemodialysis is needed. Renal history reveals commonly the pattern of acute interstitial nephritis with typical focal interstitial microhemorrhages.

Rigidity transitions and molecular structure of As x Se 1¿x glasses

T-modulated differential scanning calorimetry measurements on bulk ${\mathrm{As}}_{x}{\mathrm{Se}}_{1\ensuremath{-}x}$ glasses show that the glass transition temperature ${T}_{g}(x)$ variation at $xl0.12$ is linear with a slope ${\mathrm{dT}}_{g}/dx=4.1\ifmmode^\circ\else\textdegree\fi{}\mathrm{C}/\mathrm{at}. %\mathrm{As},$ and the nonreversing heat flow, $\ensuremath{\Delta}{H}_{\mathrm{nr}}(x)$ almost vanishes in the 0.291(1)x0.37(1) composition range. These thermal results analyzed by agglomeration theory and constraint theory suggest that in addition to $\mathrm{As}({\mathrm{Se}}_{1/2}{)}_{3}$ units, quasitetrahedral ${\mathrm{S}\mathrm{e}=\mathrm{A}\mathrm{s}(\mathrm{S}\mathrm{e}}_{1/2}{)}_{3}$ units also serve to crosslink ${\mathrm{Se}}_{q}$ chains at $x\frac{2}{5}. $ The results also suggest that rigidity onsets at ${r}_{c}(1)=2.29(1)$ and the transition to the stressed rigid phase occurs at ${r}_{c}(2)=2.37(1),$ below the chemical threshold at ${r}_{\mathrm{ct}}=2.40$ (or $x=\frac{2}{5}). $
