Joint Power Allocation and User Scheduling for Device-to-Device-Enabled Heterogeneous Networks With Non-Orthogonal Multiple Access

Device-to-device (D2D) communications-enabled dense heterogeneous networks (HetNets) with non-orthogonal multiple access (NOMA) are promising solutions to meet the high-throughput requirement and support massive connectivity. In this paper, we propose a novel framework on the D2D-enabled HetNets with NOMA, where small cells underlay the uplink spectrum of macrocells to make full use of spectrum resources, NOMA technique is invoked to serve more downlink users simultaneously, and D2D-enabled multi-hop transmission is established to enhance signal reception of the far users (FUs) on cell edge. We investigate joint power allocation and user scheduling to maximize the ergodic sum rate of the near users (NUs) in the small cells while guaranteeing the quality-of-service requirements of the FUs and the macro-cell users. The optimal solution to this problem is complexity-prohibitive especially with large numbers of users and small base stations (SBSs) because it requires an exhaustive search over all possible combinations of SBSs, NUs, and FUs. To simplify the solution, we develop a two-step approach by decomposing the original problem into a power allocation problem and a user scheduling problem. We derive the closed-form solution of the power allocation problem via analyzing the objective function and constraints. The user scheduling problem is a joint user pairing and access point assignment problem. To solve it, we propose an SBS-NU-FU matching algorithm to obtain a near-optimal one-to-one three-sided matching of SBSs, NUs, and FUs. The simulation results show that the two-step method gets around 95% of the system throughput of the optimal one and can significantly improve the spectral efficiency of the D2D-enabled HetNets.
Nitrogen fertilizers promote plant growth and assist in manganese (Mn) accumulation by Polygonum pubescens Blume cultured in Mn tailings soil

Abstract This study examined how different nitrogen (N) forms and application levels promote plant growth and assist in manganese (Mn) remediation of Polygonum pubescens Blume (P. pubescens) cultured in soil with a high Mn level. The effects of ammonium chloride (a) and urea (u), at three application levels (10, 20, and 30 mg L−1 N) and control (no N addition, CK) on the growth, Mn accumulation, and enzymatic anti-oxidative defenses of P. pubescens were examined. In general, both ammonium-N and urea-N promoted the plant mass and height of P. pubescens. The total Mn amount of roots, stems, and leaves in N treatments were higher (p < 0.05) than that of CK. The ammonium-N treatments showed greater plant biomass and Mn accumulation compared to the urea-N ones. In general, the accumulations of Mn, Cr, Zn, and Cu were significantly lower (p < 0.05) in the N fertilizer treatment than those in the control; while the accumulations of Pb were higher (p < 0.05) in P. pubescens across all N fertilizer treatments than those in the control. The N addition decreased the contents of O2− and H2O2 in the leaves of P. pubescens, while increasing the activities of enzymatic anti-oxidative defenses.
Validity and Test-Retest Reliability of the 1080 Quantum System for Bench Press Exercise.

Boehringer, S and Whyte, DG. Validity and test-retest reliability of the 1080 Quantum System for bench press exercise. J Strength Cond Res XX(X): 000-000, 2019-This study assessed the validity and reliability of the 1080 Quantum (1080Q) during the bench press exercise. Twenty-seven resistance-trained men (28 ± 4 years; body mass 88.9 ± 12.8 kg; 1 repetition maximum [1RM] bench press 94.8 ± 10.7 kg) completed 2 test-retest sessions, separated by 1 week. In each session, subjects performed single repetitions at 30, 40, 50, 60, 70, and 80% of their bench press 1RM. Mean velocity (Vmean), peak velocity (Vpeak), mean force (Fmean), peak force (Fpeak), mean power (Pmean), and peak power (Ppeak) were simultaneously assessed using the 1080Q Synchro and a linear position transducer (GymAware; Kinetic Performance Technology, Canberra, Australia). The overall performance of the 1080Q was both valid (r = 0.94-1.00) and reliable (coefficient of variation [CV] = 1.7-8.0%, intraclass correlation coefficient [ICC] = 0.90-1.00) for all measures, although both fixed and systematic biases were present. When assessed at each of the relative loads, the 1080Q remained valid for all measures apart from Fmean at 30% 1RM (r = 0.78) and Fpeak at 70 (r = 0.81) and 80% (r = 0.57) 1RM. The 1080Q also demonstrated excellent reliability at all relative loads apart from the heaviest, where Vmean (CV = 11.0%, ICC = 0.69), Pmean (CV = 11.4%, ICC = 0.65), and Ppeak (CV = 10.2%, ICC = 0.79) reliability was reduced. These data indicate that athletes and strength and conditioning coaches can confidently use the 1080Q to monitor training progression; however, caution should be taken when assessing performance measures at the either end of the load spectrum.
Terahertz Metamaterial Absorbers Implemented in CMOS Technology for Imaging Applications: Scaling to Large Format Focal Plane Arrays

We present the design and fabrication of terahertz (THz) metamaterial (MM) absorbers and their monolithic integration into a commercial CMOS technology along with its respective readout electronics to produce a low-cost, uncooled, and high resolution THz camera. We first describe the work done on single band and broadband MM absorbers on custom substrates, then progress with a description of the integration of such resonators into a six metal layer 180 nm CMOS process and its coupling with two types of microbolometer sensors: Vanadium oxide (VOx) and silicon (Si) pn diode. Additionally, we demonstrate the integration of the THz sensors with readout electronics to form a monolithic THz focal plane array (FPA). Reflection images of a metallic object hidden in a manila envelope are recorded using both the VOx and Si pn diode detectors, demonstrating the suitability of the technology for stand-off detection of concealed objects. Finally, we present the current work toward scaling this technology into a 64 × 64 FPA.
Development of Light-Weight and Rapidly Deployable Cable-Driven Robot

Visual inspecting of airplanes is one of the most crucial and complex task of airplanes service. Inspecting of airplanes is very important, since it allows to prevent aviation accident. Airplane hull inspection mainly is conducted by humans, resulting in time consuming, inefficiencies of human inspection and dangers to workers. An automated approach to perform the inspection is more preferable. In this paper an automated solution that can be implemented in a hangar conditions or at airfield is suggested. The solution represents a group of a robot-manipulator on a mobile platform and a cable-driven robot. The mobile robot is needed to perform inspecting of the plane's bottom, the cable-driven robot with special tools is needed in order to implement visual inspection of the plane's top. This study focuses on the development of a light-weight and rapidly deployable cable-driven robot. The system kinematics, dynamics, and cable tension analysis are described in the article. A simplified prototype of the light-weight rapidly deployable cable-driven robot has been developed. The model of the robot consists of low weight aluminum frame, four motors attached with pulleys, four cables, and a platform, which is a base for a tool installation. A low number of parts and light weight of the robot ensure its easy transportation, as well as quick installation and dismantling.
Antibiotic-impregnated autogenic cancellous bone grafting is an effective and safe method for the management of small infected tibial defects: a comparison study.

OBJECTIVE Bone grafting plays an important role in reconstructing infected tibial nonunions. The effects of antibiotic-impregnated bone grafting in infection elimination and bone incorporation was reported in this retrospective study. METHODS Ninety-six patients treated for infected tibial nonunions were evaluated. These patients were managed with local antibiotic bead therapy and staged antibiotic-impregnated autogenous cancellous bone graft or pure autogenous cancellous bone graft. Patients were randomized to antibiotic-impregnated bone grafting or bone grafting-only groups on the basis of whether the admission date was odd or even. Patients were divided into two groups (antibiotic-impregnated bone grafting group and pure cancellous bone grafting group), according to the procedure used in preparing the bone grafts. The antibiotic-impregnated bone grafting group included 37 men and 9 women whose average age was 36 years (range, 17 to 72 years). The average follow-up period was 4.8 years. By using the Cierny-Mader staging classification of chronic osteomyelitis, 32 of 46 patients (70%) were stage 4A, and 14 of 36 patients (30%) were stage 4B. The pure cancellous bone grafting group included 39 men and 11 women whose average age was 37 years (range, 18 to 72 years). The average follow-up period was 4.5 years (range, 4 to 6 years). Thirty-nine of 50 patients (78%) were stage 4A, and 11 of 50 patients (22%) were stage 4B. The bone defects in both groups ranged from 2 to 4 cm. RESULTS Wound healing and bony union were achieved in the antibiotic-impregnated bone grafting group. Only two patients had recurrent infections. The infection arrest rate was 95.6%. However, 9 of 50 patients in the pure cancellous bone grafting group had recurrent infections. The infection arrest rate was 82%. The antibiotic-impregnated bone grafting group had significantly superior results (95.6% vs. 82% chi2 test, p < 0.05) in infection elimination than the pure cancellous bone grafting group. CONCLUSION After 4 to 6 years of follow-up, our results suggest that the use of impregnating antibiotics have no adverse effects on autogenic cancellous bone graft incorporation and could help to eliminate infection effectively.
Space Use and Movement of Urban Bobcats

Simple Summary The bobcat (Lynx rufus) is a medium-sized carnivore that lives in remote and urban habitats. Here, we evaluate how bobcats exploit a highly urbanized section of the Dallas–Fort Worth metroplex, Texas, USA by evaluating their space use and activity patterns. We found that bobcats use more natural habitat areas within urban areas, such as agricultural fields and creeks, and avoid highly anthropogenic features, such as roads. Bobcat home ranges overlap one another, especially in areas with preferred habitat types, but they are neither avoiding nor attracted to one another during their daily movements. This study highlights how bobcats are able to navigate a built environment and the importance of green space in such places. Abstract Global urbanization is rapidly changing the landscape for wildlife species that must learn to persist in declining wild spacing, adapt, or risk extinction. Many mesopredators have successfully exploited urban niches, and research on these species in an urban setting offers insights into the traits that facilitate their success. In this study, we examined space use and activity patterns from GPS-collared bobcats (Lynx rufus) in the Dallas–Fort Worth metroplex, Texas, USA. We found that bobcats select for natural/agricultural features, creeks, and water ways and there is greater home-range overlap in these habitats. They avoid roads and are less likely to have home-range overlap in habitats with more roads. Home-range size is relatively small and overlap relatively high, with older animals showing both greater home-range size and overlap. Simultaneous locations suggest bobcats are neither avoiding nor attracted to one another, despite the high overlap across home ranges. Finally, bobcats are active at all times of day and night. These results suggest that access to natural features and behavioral plasticity may enable bobcats to live in highly developed landscapes.
Carrier Frequency Offset Estimation Bound for OFDM-Based Single Relay Networks With Multipath Receptions

In this paper, the carrier frequency offset (CFO) estimation bound is presented to assess the CFO estimation performance of an orthogonal frequency division multiplexing (OFDM)-based single relay network over multipath channels, for which an amplify-and-forward (AF) protocol is adopted. We theoretically derive the Cramer–Rao bounds (CRBs) of the CFO estimation in multipath channels. Unlike the analysis in flat fading channels where the CFOs of the two hops can be combined together as a single estimation parameter, the CFOs of the source-relay (S-R) and the relay-destination (R-D) links are required to be evaluated separately in multipath channels. The first-order Taylor series expansion is applied to simplify the calculation of the inverse of the covariance matrix which reflects the correlation of multipath channels and relay noise. In addition, we derive the modified CRB (MCRB) of the CFO estimation to get more insight into the influence of the system parameters on the CRB performance. Through computer simulations, we evaluate the impact of multipath channels, the operating signal-to-noise ratio (SNR), and the number of effective multipaths on the CFO estimation error in the dual-hop relay transmission.
Physiological modifications of seston in response to physicochemical gradients within Lake Superior

In September 2011, we investigated the distribution and composition of dissolved and particulate phosphorus (P) pools throughout Lake Superior, a large P‐limited freshwater ecosystem. Average seston particulate P (PP) concentrations in the deep chlorophyll maximum (DCM; 85 ± 28 nmol L−1) were significantly greater than in the epilimnion (63 ± 22 nmol L−1). In contrast, average particulate organic carbon (POC) : PP (mol : mol) ratios showed the opposite pattern (DCM = 303 : 1 vs. epilimnion = 455 : 1). Mean seston nucleic acid—P concentrations were invariant between the epilimnetic (23 ± 18 nmol L−1) and DCM (26 ± 18 nmol L−1) layers, but significantly greater concentrations of intact polar membrane—derived phospholipids were found in the DCM (6 ± 2 nmol L−1) relative to the epilimnion (4 ± 2 nmol L−1). Phospholipids were a minor proportion of PP (7–14%) and total membrane lipids (< 30%). Rather, our results suggest that microbial flora of Lake Superior substituted non‐phosphorus lipids for phospholipids. In the nitrogen (N)—rich waters, N‐based betaine lipids dominated (39–42%) the lipid pool, and concentrations were significantly greater in the P‐poor epilimnetic seston. Sulfolipids were also abundant and significantly greater in the epilimnion (7 ± 2 nmol L−1) than in the DCM (4 ± 2 nmol L−1), despite low sulfate concentrations relative to marine environments. Our results demonstrate for the first time the importance of plankton producing non‐phosphorus lipids for phospholipids as a strategy for reducing cellular P inventories in lacustrine regimes.
NECTIN4 (PVRL4) as Putative Therapeutic Target for a Specific Subtype of High Grade Serous Ovarian Cancer—An Integrative Multi-Omics Approach

In high grade serous ovarian cancer patients with peritoneal involvement and unfavorable outcome would benefit from targeted therapies. The aim of this study was to find a druggable target against peritoneal metastasis. We constructed a planar—scale free small world—co-association gene expression network and searched for clusters with hub-genes associated to peritoneal spread. Protein expression and impact was validated via immunohistochemistry and correlations of deregulated pathways with comprehensive omics data were used for biological interpretation. A cluster up-regulated in miliary tumors with NECTIN4 as hub-gene was identified and impact on survival validated. High Nectin 4 protein expression was associated with unfavorable survival and (i) reduced expression of HLA genes (mainly MHC I); (ii) with reduced expression of genes from chromosome 22q11/12; (iii) higher BCAM in ascites and in a high-scoring expression cluster; (iv) higher Kallikrein gene and protein expressions; and (v) substantial immunologic differences; locally and systemically; e.g., reduced CD14 positive cells and reduction of different natural killer cell populations. Each three cell lines with high (miliary) or low NECTIN4 expression (non-miliary) were identified. An anti-Nectin 4 antibody with a linked antineoplastic drug–already under clinical investigation–could be a candidate for a targeted therapy in patients with extensive peritoneal involvement.
Deaminase-Independent Inhibition of Parvoviruses by the APOBEC3A Cytidine Deaminase

The APOBEC3 proteins form a multigene family of cytidine deaminases with inhibitory activity against viruses and retrotransposons. In contrast to APOBEC3G (A3G), APOBEC3A (A3A) has no effect on lentiviruses but dramatically inhibits replication of the parvovirus adeno-associated virus (AAV). To study the contribution of deaminase activity to the antiviral activity of A3A, we performed a comprehensive mutational analysis of A3A. By mutation of non-conserved residues, we found that regions outside of the catalytic active site contribute to both deaminase and antiviral activities. Using A3A point mutants and A3A/A3G chimeras, we show that deaminase activity is not required for inhibition of recombinant AAV production. We also found that deaminase-deficient A3A mutants block replication of both wild-type AAV and the autonomous parvovirus minute virus of mice (MVM). In addition, we identify specific residues of A3A that confer activity against AAV when substituted into A3G. In summary, our results demonstrate that deaminase activity is not necessary for the antiviral activity of A3A against parvoviruses.
A 230–260-GHz Wideband and High-Gain Amplifier in 65-nm CMOS Based on Dual-Peak $G_{{\mathrm{max}}}$ -Core

This paper proposes a wideband and high-gain amplifier design technique based on a dual-peak maximum achievable gain (<inline-formula> <tex-math notation="LaTeX">$G_{\mathrm{ max}}$ </tex-math></inline-formula>) core. The proposed technique achieves a power gain close to <inline-formula> <tex-math notation="LaTeX">$G_{\mathrm{ max}}$ </tex-math></inline-formula> at two frequencies simultaneously, thereby enabling the implementation of a wideband and high-gain amplifier. The input, output, and interstage matching networks are designed in a gain compensating manner, considering the gain variation of the dual-peak <inline-formula> <tex-math notation="LaTeX">$G_{\mathrm{ max}}$ </tex-math></inline-formula>-core. The four-stage amplifier based on an identical dual-peak <inline-formula> <tex-math notation="LaTeX">$G_{\mathrm{ max}}$ </tex-math></inline-formula>-core at each stage is implemented in a 65-nm CMOS process. The measured results show a 3-dB bandwidth of 30 GHz (227.5–257.2 GHz), a gain of 12.4 ± 1.5 dB, and a peak power added efficiency (PAE) of 1.6% with dc power dissipation of 23.8 mW, which corresponds to the widest 3-dB bandwidth and gain per stage comparable to those of other reported CMOS amplifiers operating at frequencies above 200 GHz.
Anxiety–Depression of Dialysis Patients and Their Caregivers

Background and Objectives: Anxiety–depression of patients undergoing hemodialysis has a strong relation with the levels of anxiety–depression of their caregivers. The aim of this study was to evaluate anxiety–depression of dialysis patients and their caregivers. Materials and Methods: In this cross-sectional study, 414 pairs of patients and caregivers from 24 hemodialysis centers of Greece completed the Hospital Anxiety and Depression Scale (HADS). The statistical analysis of the data was performed through the Statistical Program SPSS version 20.0. The statistical significance level was set up at 5%. Results: The mean age of patients was 64 (54.06–72.41) years old and the mean duration of hemodialysis was 36 (16–72) months. The mean age of caregivers was 54 (44–66) years old. Of the total sample, 17.1% (n = 71) of patients had high levels of anxiety and 12.3% (n = 51) had high levels of depression. Additionally, 27.8% (n = 115) of caregivers had high levels of anxiety and 11.4% (n = 47) had high levels of depression. Caregivers had higher levels of anxiety when their patients had high levels of anxiety as well (42.3%). Additionally, they had higher levels of depression when their patients had high levels of depression as well (17.6%). Conclusions: The results of this study showed a significant association between the levels of anxiety and depression among patients and caregivers. There is a necessity for individualized assessment of dialysis patients and their caregivers and the implementation of specific interventions for reducing the levels of anxiety and depression among them.
Tele-glaucoma versus clinical evaluation: The New Jersey Health Foundation Prospective Clinical Study

Introduction Glaucoma, the second most common cause of blindness, is normally detected in clinic. With technological improvements, tele-glaucoma exams can identify these changes off-site. The quality of tele-glaucoma exams needs to be compared with that of traditional exams. This study’s purpose was to validate the tele-glaucoma programme, which allows a physician comprehensive access to patients’ data, by comparing results to clinical examinations. Methods A prospective study of 107 subjects evaluated in clinic and then tele-glaucoma stations, which consisted of non-mydriatic fundus photography, puff-tonometry, auto-refraction and Optical Coherence Tomography (OCT). The OCT captured central corneal thickness, angle anatomy, cup-to-disc ratio (CDR), retinal nerve fibre layer distribution and posterior-pole ganglion cell complex data. Results Intraocular pressure (IOP) comparisons between clinical and tele-glaucoma exams had strong positive Pearson correlation coefficients (0.8248 OD, 0.8672 OS). Strong positive correlations were seen for CDR (0.7835 OD, 0.8082 OS) as well as diagnosis (glaucoma, no glaucoma or glaucoma suspect). A moderate positive correlation was seen for return to clinic time (RTC). Tele-glaucoma had an average lower RTC (2.7 vs 3.9 months). Tele-glaucoma was more likely to elicit a non-glaucomatous diagnosis not found in clinic vs a diagnosis found only in clinic (18% vs 5% of subjects). Discussion Tele-glaucoma allows for detecting glaucoma remotely. These advancements alleviate patient difficulties with obtaining adequate glaucoma screenings and helps ophthalmologists triage patients with more severe pathology. Our study indicates that our tele-glaucoma protocol is comparable to a clinical exam in its ability to detect glaucoma. Further studies will be needed for off-site testing and transferring data separately for analysis.
A new fusicoccane diterpene and a new polyene from the plant endophytic fungus Talaromyces pinophilus and their antimicrobial activities

Abstract A new fusicoccane diterpene, pinophicin A (1), and a new polyene, pinophol A (2), were isolated from the plant endophytic fungus Talaromyces pinophilus obtained from the aerial parts of Salvia miltiorrhiza. The structures and relative configurations of 1–2 were determined by the analysis of extensive spectroscopic data, chemical method, and comparison with known compounds. Compound 2 exhibited weak antibacterial activity against Bacterium paratyphosum B with an MIC value of 50 μg/mL. Graphical Abstract
