Joint channel selection and optimal power allocation for multi-cell D2D communications underlaying cellular networks

Device-to-device (D2D) communication underlaying cellular networks can improve the spectrum efficiency as a result of sharing the radio resources allocated to cellular user equipments (CUEs). However, the severe interference between D2D and CUEs communications may lead to performance degradation of cellular system if not coordinated properly. In this study, a joint channel assignment and power allocation algorithm is proposed, which addresses the intra-cell and inter-cell interference management problems for D2D communication underlaying cellular network. The case of multiple D2D-user equipments (DUEs) sharing the same channel while each DUE can reuse multiple channels is considered. The proposed algorithm is designed with two complementary steps in such a way that its computational complexity can be adapted according to the network condition. The preliminary set of CUEs candidate channels that can be reused by each DUE is adaptively decided in the first step. In the second step, the optimal power allocation for each DUE is determined using Lagrangian dual decomposition to maximise the network sum-rate. Simulation results show that the proposed algorithm outperforms the current comparable algorithms especially in terms of achievable throughput. Moreover, the effect of various system parameters on the performance of the proposed technique is also investigated.
Timing for dose-down of 5-ASA depends on mucosal status with ulcerative colitis

Abstract Objective: Although aminosalicylic acid (ASA) preparations have been used as first-line drugs for the treatment of ulcerative colitis (UC), no consistent view has been established regarding the ASA dose during the remission-maintenance phase of the disease. In this study, we examined whether the ASA dose should be reduced during the remission-maintenance phase. Materials and methods: This study included 203 patients in the remission-maintenance phase of UC. The Mayo endoscopic subscore (MES) was used to evaluate mucosa. Comparison and analysis were performed between patients whose ASA dose had been unchanged and whose dose had been reduced, between patients with endoscopic healing (EH) group and those without endoscopic healing (WEH) group, and between patients with an MES of 0 and 1. Results: Comparison between the unchanged-ASA and reduced-ASA groups revealed that the remission-maintenance rate was higher in the unchanged-ASA group (p < 0.001). Next, the remission-maintenance rate was higher in the EH/unchanged-ASA group than in the EH/reduced-ASA group (p = 0.042). Comparison between the MES 0 and 1 groups revealed that the remission-maintenance rate was higher in the MES 0 group (p = 0.007). In addition, no significant difference in remission-maintenance rates was observed between the MES 0/unchanged-ASA group and the MES 0/reduced-ASA group (p = 0.108). Conclusion: When the same ASA dose is maintained regardless of the presence or absence of EH, remission is more likely to be maintained. If the ASA dose must be reduced, dose reduction is more advantageous after an MES of 0 is achieved.
Following the Imprint of the ECB's Asset Purchase Programme on Global Bond and Deposit Flows

We trace the imprint of the ECB's expanded asset purchase programme (APP) on international bond portfolios and euro-denominated deposits. Our analysis suggests that non-bank financial institutions (NBFIs) located outside the euro area sold large volumes of euro area government bonds and kept a substantial fraction of the proceeds as euro-denominated deposits, primarily in UK-resident banks. Since the APP's modalities did not allow the NBFIs to engage directly with the Eurosystem, their deposits left an international trail of euro-denominated claims. Our findings highlight the role of the United Kingdom as a gateway to the euro area financial system for investors outside the euro area.
Preparation of the patient for awake flexible fiberoptic bronchoscopy.

Since the introduction of flexible fiberoptic bronchoscopy (FFB) technology the ability to actually visualize and selectively perform a biopsy ofthe entire upper airway, as well as much of the lower airway, has established this technique as an invaluable diagnostic tool. FFB is usually performed in procedure rooms without the use of an endotracheal tube and without the assistance of an anesthesiologist. Most FFBs are assisted by sedation and local anesthesia. They are often performed using the transnasal approach”#{176}; however, the oral approach is also commonly employed . The transnasal approach precludes damage to the instrument from closure of the teeth and offers optimal anatomic alignment for entrance into the larynx and trachea.3 Although FFB is considered a relatively safe procedure when performed by a knowledgeable, experienced operator, it is not without risk. Obstruction of the airway, hypoxia, arrhythmias, local anesthetic toxic reactions, and oversedation are some of the possible complications that may occur. ’249 The best way to identify hypoxemia and arrhythmias when they manifest is to rely on pulse oximeters and continuous cardiac rhythm monitors. Patient acceptance is predicated on the individual’s comfort during such an experience. Repeated episodes ofpain, coughing, retching, and vomiting detract from the efficient application ofthis method. Such episodes predispose to ill will between patient and physician. Fortunately, these side effects are usually avoidable with proper preparation, which actually begins with an explanation of the patient’s condition and the specific indication for FFB in the particular case. A brief discussion of the procedure and its possible complications, including discomfort, should then en-
Spermatozoa and spermatids retrieved from frozen reproductive organs or frozen whole bodies of male mice can produce normal offspring

Cryopreservation of male germ cells is a strategy to conserve animal species and strains of animals valuable to biomedical research. We tested whether mouse male germ cells could be cryopreserved without cryoprotection by simply freezing epididymides, testes, or whole bodies. The reproductive organs were isolated from killed mice and frozen for 1 week to 1 year at −80°C before spermatozoa and spermatids were collected and injected into mature oocytes. Normal pups were born irrespective of strains tested (ICR and C57BL/6). Epididymides and testes frozen and transported internationally to another laboratory by air could produce pups of inbred C57BL/6 mice. Testicular spermatozoa retrieved from the bodies of male mice (BALB/c nude and C3H/He strains) that had been kept frozen (−20°C) for 15 years could also produce normal offspring by microinsemination. Thus, freezing of either male reproductive organs or whole bodies is the simplest way to preserve male germ cells. Restoration of extinct species could be possible if male individuals are found in permafrost.
Ionogel—Based Composite Material for CO2 Sensing Deposited on a Chemiresistive Transducer

A novel miniaturized carbon dioxide (CO2) sensor based on an IDE transducer is described and characterized. The CO2 sensor based on different semiconducting metal oxide and ionogel composites films deposited by ink-jet printing. The sensor is operated as a simple chemiresistor. The sensors were investigated under trace gas exposure (CO2, NO2, CO and humidity). The CO2 sensitivity is found to be exceptionally high and the sensing mechanism is supposed to be entirely different compared to those of the components of the composite.
An 11-year review of dermatomyositis in Asian patients.

INTRODUCTION Dermatomyositis (DM) is a multisystem inflammatory disease with a strong association with malignancy. We aimed to describe a series of Asian patients with DM and identify any significant clinical factors associated with malignancy. MATERIALS AND METHODS This was a retrospective review of a multi-racial cohort of 69 Asian patients diagnosed with DM over an 11-year period from 1996 to 2006. RESULTS Malignancy was detected in 15 out of 68 patients (22%), the most common of which was nasopharyngeal carcinoma (7 cases). Compared to the non-malignancy group, the malignancy-associated group was older and had more male patients. There were no statistically significant clinical, serological or laboratory factors associated with a higher risk of malignancy. CONCLUSION This study highlights the importance of ongoing malignancy screening especially for nasopharyngeal carcinoma in Asian patients with DM.
The Influence of Government Size, Audit Opinion and Incumbent on Audit Delay in the Provincial Government in Indonesia

Financial statements that were not provided on time may cause those report loses their capacity to influence decisions. This study aims to examine the effects of government size, audit opinion, incumbent on audit delay in Indonesia. This study used 165 financial reports from 33 provincial government in Indonesia from 2012 to 2016. Research data was obtained from the financial audit agency and directorate general of financial balance. The dependent variable of this research is audit delay. While the independent variables include the size of government, audit opinon, dan incumbent. Multiple regression analysis was used to test the hypothesis. The test results show that audit opinion has a significant effect on audit delay. But size of government and incumbent does not have a significant effect on audit delay.
Poincaré plot analysis of heart rate variability in the diabetic patients in the UAE

Major complications such as cardiac death and cardiac autonomic neuropathy are caused by diabetic autonomic neuropathy. Heart Rate Variability (HRV) analysis has shown to detect variations in the autonomic balance of heart rate and is useful for early detection of autonomic dysfunction. This study presents the outcome of HRV analysis of short ECG recordings taken from nondiabetic and type 2 diabetes patients, applying Poincaré plot indices represented by short term variation (SD1), long term variation (SD2) and complex correlation (CCM) measure which measures the temporal dynamics, for early detection of cardiac autonomic neuropathy. SD1 and the ratio SD1/SD2 were found to be significantly lower in type 2 diabetes patients than the control group. The highest discriminatory power was observed with CCM, indicating the advantage of using a dynamic measure for HRV rather than the static Poincaré plot indices. SD1 and CCM could be markers for CVD risk in type 2 diabetic patients.
Urokinase‐type plasminogen activator enhances invasion of human T cells (Jurkat) into a fibrin matrix

The receptor for urokinase‐type plasminogen activator (uPA‐R) localizes uPA to the cell surface. The receptor‐bound uPA converts plasminogen to the trypsinlike endopeptidase plasmin. Thus uPA is involved in the initiation of pericellular proteolysis. Pericellular proteolysis is assumed to facilitate the cellular infiltration into surrounding tissue. The uPA‐R has recently been identified as a surface antigen of activated human T lymphocytes. We have characterized the uPA‐R of the human CD4+ T cell line Jurkat by immunological (flow cytometry), biochemical (ligand blotting), and physico‐chemical (Scatchard blotting) methods. The collective data suggest that the human CD4+ T cell line Jurkat expresses a cell surface receptor for uPA similar to that of myelo/monocytes and normal T cells with regard to size, affinity, ligand specificity, and antigenicity. Binding studies using exogenous uPA and subsequent functional assays revealed that receptor‐bound uPA retains its enzymatic activity. Saturation of the Jurkat cell uPA‐R with exogenous uPA facilitated cellular invasion into fibrin matrices in vitro. uPA‐dependent invasion was inhibited in the presence of an anti‐catalytic monoclonal anti‐uPA antibody. We propose that uPA‐R‐bound uPA may facilitate the invasiveness of uPA‐R‐positive T lymphocytes. J. Leukoc. Biol. 56: 110–116; 1994.
Biological Effect of Resorbable Plates on Normal Osteoblasts and Osteoblasts Derived From Pfeiffer Syndrome

Biodegradable fixation devices made of the polymers polylactide, polyglycolide and their copolymers are used routinely during maxillofacial, craniofacial, and orthopedic reconstructive surgical procedures, thanks to their property of biodegradation that avoid the need for implant removal. In particular, they are used in the treatment of craniosynostosis in pediatric patients affected by Pfeiffer syndrome, where the resorption time of 1 year or less does not interfere with the normal growth of the skull. To study the mechanism how polylactide-polyglycolide (PLPG) acid plates can induce osteoblast differentiation and proliferation in normal osteoblasts and in osteoblasts derived from a patient with Pfeiffer syndrome, the expression levels of bone-related genes were analyzed using real-time reverse transcription-polymerase chain reaction. Osteoblasts grown on the PLPG acid plates resulted in significant upregulation of mRNA expression of many genes related to osteodifferentiation during the treatment, indicating that polylactide, polyglycolide biopolymers enhance proliferation, differentiation, and deposition of matrix in osteoblasts. This study also revealed some differences in gene expression between normal osteoblasts and osteoblasts derived from patients with Pfeiffer syndrome, cultivated on PLPG acid plates.
Amazon diversification and cross‐Andean dispersal of the widespread Neotropical tree species Jacaranda copaia (Bignoniaceae)

The phylogeographical history of Neotropical species can be difficult to reconstruct because of superimposed Neogene and Quaternary histories, and because of taxonomic uncertainty. We analysed range‐wide genetic diversity in a widespread pioneer tree species, Jacaranda copaia (Aubl.) D. Don, to characterize phylogeographical structure, date the evolutionary relationships among lineages, and evaluate the role of dispersal and vicariance in establishing the present geographical range.
The Joint Influence of Control Strategies and Market Turbulence on Strategic Performance in Sales-Driven Organizations

The effect of management control efforts on organizational actors’ participation in the strategy process is investigated. Results from a survey of sales-driven organizations indicate that self, professional, activity, and output control systems have varying effects on participation in strategic activity. We also found that the influences of control systems on participation in strategic activity are moderated by market turbulence. Importantly, a direct relationship is established between participation in strategic activity and individual-level selling performance.
Face Recognition Algorithm Based on Kernel Collaborative Representation

Aiming at solving the problems of occlusion and illumination in face recognition, a new method of face recognition based on Kernel Principal Components Analysis (KPCA) and Collaborative Representation Classifier (CRC) is developed. The KPCA can obtain effective discriminative information and reduce the feature dimensions by extracting faces nonlinear structures features, the decisive factor. Considering the collaboration among the samples, the CRC which synthetically consider the relationship among samples is used. Experimental results demonstrate that the algorithm obtains good recognition rates and also improves the efficiency. The KCRC algorithm can effectively solve the problem of illumination and occlusion in face recognition.

Unrestrictive identification of non‐phosphorylation PTMs in yeast kinases by MS and PTMap

A few protein PTMs, such as phosphorylation and ubiquitination, are known to be critical in regulation of protein kinase activities. However, the roles of other PTMs have not been extensively studied in kinases. Development of a comprehensive description of all types of PTMs and discovering novel in vivo PTMs in low abundance represent major analytical challenges. Toward this goal, we have developed a strategy for systematic and accurate identification of the full‐spectrum of PTMs in yeast protein kinases. Our strategy involves isolation of GST‐fused kinase proteins, MS analysis, and unrestrictive PTM identification by PTMap algorithm. Among the 30 purified yeast kinases, we identified 27 different types of PTMs, and 53 PTM sites, among which are 13 novel mass shifts that have not been previously reported, likely representing novel PTMs. These results represent a significant expansion of our current understanding of PTMs in kinases and suggest highly complex regulation of kinase function.
Customer Concentration, Bad News Withholding, and Stock Price Crash Risk

We investigate whether the presence of major corporate customers affects firm stock price crash risk. Using data on a large sample of U.S. firms, we find that firms with a more concentrated customer base have a higher stock price crash risk. Further, we show an amplified effect of customer concentration on crash risk for firms that attach more importance to customer relations and an attenuated effect for firms with stronger third-party monitoring. Overall, we find that a concentrated customer base imposes performance pressure on managers. This induces them to withhold bad news, which ultimately results in future stock price crashes.
Errors in temperature measurement by thermocouple probes during ultrasound induced hyperthermia.

A major problem in the use of localised hyperthermia for treatment of malignant tumours is to obtain an accurate measurement of the temperature in the tissue being treated. Thermocouple probes have generally been employed for measuring temperature elevation during ultrasound irradiation. However, when small objects such as thermocouples are in an ultrasound field in a medium such as tissue, viscous forces acting between the object and the tissue will cause an additional local rise in temperature (Fry & Fry, 1954a, b; Dunn, 1962; Hynynen et al, 1982). This will produce an error in any measurement of tissue temperature with invasive probes. The magnitude of the temperature elevation resulting from shear viscosity has been measured for 50 μm thermocouples in tumour tissue.
Mechanics modeling of eMUF FC BGA molding process for bump deformation control

eMUF (exposed die molded underfill) transfer-mold process of FCBGA (flip chip ball grid array) is one of the most popular integrated circuit package assembly solution, which has the benefits of low cost, high throughput, high thermal dissipation, low profile, good protection of the bump and the top side solder ball of PoP (package on package) bottom package, available laser abrasion process for PoP bottom package. One of the most important problem of this process is there have external forces (a part of mold clamping force and the fluid transfer pressure of the molding compound) applied on the package before bump protection. For molding mechanics analysis, the structure of the eMUF molding process is a substrate with flipped chip placed on the bottom mold and a releasing film covered lid type top mold pressed on the substrate meanwhile contact the backside of the chip. The clamping force is partially applied on the substrate and partially on the chip. After mold clamping, the molding compound is pumped into the surface of the substrate include the bump area and then compressed into high pressure to make sure the mold cavity is full of molding compound and avoid the existence of the void. Generally, the clamping force is dynamic controlled simultaneous with the increase of the transfer pressure of molding compound. The problem could be separate into two parts, force and displacement balances before and after the molding compound transfer pressure build up. The force unbalance may damage the weakest part of the package; generally, the damage will appear at the UBM, IMC or C4 bump. Additionally, die back side mold flash is another defect may appear if the displacement balance not deal well. A static force and displacement balances mechanics model proposed in this article provides a good comprehension on the mechanism of the eMUF molding process. It indicates that the solder bump is easy to have plastic deformation, and gives a reasonable bump deformation prediction. This model is a powerful tool to help the process engineer to select process and mold parameters, include the molding compound transfer pressure, adaptive and full clamping force, and the mold cavity depth, for different product and process incoming situation. Meanwhile, for next generation assembly, it indicates that the molding process window of eMUF should have a stricter control, due to the smaller of the bump size. Furthermore, it told that a process refinement action for reducing bump bearing external force is pressing.
