Joint Uplink and Downlink Resource Allocation for D2D Communication Underlying Cellular Networks

Device-to-device (D2D) communication is a promising technique to improve the spectral efficiency of cellular networks. In this paper, we investigate the joint uplink and downlink resource allocation problem to maximize the sum data rate of the system while guaranting the quality of service (QoS) for both cellular user equipments (CUEs) and D2D user equipments (DUEs). In particular, we jointly consider both the uplink and downlink subcarrier resources for DUEs to reuse and formulate the optimization problem as a mixed integer nonlinear programming problem (MINLP) which is generally NP-hard. To make the problem tractable, a two-step scheme is proposed. First, the optimal power allocation is formulated as a non-linear programming problem and the optimal solution is achieved by searching among a finite set. Then, a maximum weight bipartite matching scheme is developed to select the best subcarrier for each DUE. Simulation results show that our proposed algorithm can significantly improve the system performance.
Choice Parameters in L 2 Hakima Guella

Since the early 1980s the question whether Universal Grammar (UG) plays a role in second language acquisition has been extensively debated. Several views can be distinguished. According to Bley-Vroman’s (1990) Fundamental Difference Hypothesis, L2 learners do not have access to UG. The Full Access Full Transfer Hypothesis (Schwartz & Sprouse 1994, 1996) states that L2 learners transfer their L1 grammar in the initial state of L2 acquisition, but that their interlanguages can be characterized in terms of UG parameters distinct from those found in L1. According to the Full Access (No Transfer) Hypothesis (Flynn & Martohardjono 1994, Flynn 1996, Epstein et al. 1996, 1998), the initial state of L2 grammars is not L1. According to Platzack’s (1996) Initial Hypothesis of Syntax, the initial state of L2 grammars is UG. Ionin’s (2003) study on the acquisition of the English article by Russian and Korean L2 learners is an attempt to show that L2 learners have Full Access to UG. Ionin shows that these learners, who do not have articles in their L1, fluctuate between two parameters in their choice of the article in English: the definiteness parameter (present in the L2 grammar) or the specificity parameter (an UG option present in languages distinct from their L1 or L2). Since these learners base their choice on the specificity parameter in part of the cases, Ionin argues that they still have access to UG. Russian and Korean learners of English have to reset a parameter and to set a parameter concerning the article. They have to reset the article/no article parameter (and pass through an initial state in which they transfer the no article parameter from their L1) and they have to set the definiteness/specificity parameter. Ionin’s study concerns the setting of the last parameter. The Russian and Korean L2 learners of English cannot transfer this parameter from their L1. In this paper we investigate whether learners who can transfer the setting of the definiteness/specificity parameter from their L1 also fluctuate between the definiteness and the specificity parameter in their choice of the L2 article, which could provide even stronger support for the hypothesis that L2 learners have access to UG. We studied the acquisition by Dutch L2 learners of Arabic, both definiteness-based languages, to see whether their interlanguages presented specificity effects. The paper is organized as follows. In section 2, we discuss the definiteness and the specificity parameters, and their setting in Dutch and Arabic. In section 3, we present our hypothesis, our research and the results. In section 4, we discuss our results. Finally, in section 5, we summarize the conclusions.
MODULATION OF SYMPATHOVAGAL BALANCE AFTER CHANDRANADI PRANAYAMA IN HEALTHY VOLUNTEERS

Background and objectives: Regardless of prevailing advances in yoga research, the immediate benefit of chandranadi pranayama (CNP) on heart rate variability was not explored. Therefore, in this study, we planned to study the immediate effect of CNP on heart rate, blood pressure and HRV. Methods: One hundred and ten medical students were randomly divided into two groups; control group (n=55) and CNP group (n=55). CNP group participants were individually trained to perform CNP by an experienced yoga instructor with a regularity of 6 breaths/min for five minutes. CG volunteers didn’t undergo CNP, Pre and post intervention HR, BP measurements and spectral analysis of HRV was done in both the groups. The paired student’s t test was used to determine significant differences. Results: There was a significant decrease in HR (p<0.01), BP (p<0.05), LFnu (p<0.05), LF/HF (p<0.001) and increase in HFnu (p<0.01) followed by five minutes of CNP in CNP group. Further, HR, SBP, DBP was reduced by 9.10%, 4.80%, 7.75 % respectively. HRV results showed 7.59% reduction in LFnu, 17.8% reduction in LF/HF and HF was increased by 12.37%. There were no significant changes in CG. Conclusion: It is concluded that CNP is beneficial in reducing HR, BP and to improve Sympathovagal balance. We advise that this effective method be included with the management protocol of hypertension and utilized when immediate reduction of blood pressure is required in day-to-day as well as clinical situations.
Bone mineral density and hormonal status in adolescent athletic girls

The aim of this study was to determine the relationships of bone mineral density (BMD) and content (BMC) with selected fasting hormones in adolescents with different exercise training patterns. The participants were female athletes of weight-loaded (n=23) and weight-supported (n=24) sports, and 33 non-athletic girls aged 13–15 years. BMD (g/cm2) and BMC (g) at the femoral neck (FN) and lumbar spine (LS) were measured. Venous blood samples were drawn to determine the concentration of insulin-like growth factor-1 (IGF-1), IGF binding protein-3 (IGFBP-3), estradiol, visfatin, adiponectin, leptin, insulin, and glucose. After adjusting for age, height, and body mass, the relationships of BMD variables with IGF-1, IGF-1/IGFBP-3 molar ratio, estradiol, and leptin levels remained significant only in the weight-loaded sport group (r=0.41–0.60; p<0.05). Adiponectin was inversely correlated to FN and LS BMD and BMC (r=–0.47–0.62; p<0.05) in weight-supported sport group only, but after adjustments for age, height, and body mass, these associations disappeared. In this study, concentrations of visfatin, a fairly new adipocytokine, were not related to bone parameters in adolescent girls with different training patterns.
Non-Orthogonal Unicast and Multicast Transmission for Massive MIMO With Statistical Channel State Information

We investigate non-orthogonal unicast and multicast (NOUM) transmission for massive multiple-input multiple-output systems, where only statistical channel state information of all user terminals is available at the base station. We adopt a weighted sum of the achievable ergodic unicast rate and multicast rate as the design objective. We first show the closed-form eigenvectors of the optimal unicast and multicast transmit covariance matrices, respectively, which reveals the optimality of beam domain transmission and simplifies the large-dimensional matrix-valued NOUM transmission design into a beam domain power allocation problem. Via invoking the concave-convex procedure, we, then, propose an efficient iterative beam domain power allocation algorithm with guaranteed convergence to a stationary point. In addition, we derive the deterministic equivalent of the objective in each iteration to further reduce the optimization complexity. Simulation results show that the proposed NOUM transmission can provide a significant performance gain in terms of the achievable ergodic unicast-multicast rate region over the conventional orthogonal approach.
Trends and regional distributions of land and ocean carbon sinks

Abstract. We show here an updated estimate of the net land carbon sink (NLS) as a function of time from 1960 to 2007 calculated from the difference between fossil fuel emissions, the observed atmospheric growth rate, and the ocean uptake obtained by recent ocean model simulations forced with reanalysis wind stress and heat and water fluxes. Except for interannual variability, the net land carbon sink appears to have been relatively constant at a mean value of −0.27 Pg C yr−1 between 1960 and 1988, at which time it increased abruptly by −0.88 (−0.77 to −1.04) Pg C yr−1 to a new relatively constant mean of −1.15 Pg C yr−1 between 1989 and 2003/7 (the sign convention is negative out of the atmosphere). This result is detectable at the 99% level using a t-test. The land use source (LU) is relatively constant over this entire time interval. While the LU estimate is highly uncertain, this does imply that most of the change in the net land carbon sink must be due to an abrupt increase in the land sink, LS = NLS – LU, in response to some as yet unknown combination of biogeochemical and climate forcing. A regional synthesis and assessment of the land carbon sources and sinks over the post 1988/1989 period reveals broad agreement that the Northern Hemisphere land is a major sink of atmospheric CO2, but there remain major discrepancies with regard to the sign and magnitude of the net flux to and from tropical land.
Music preferences as signs of who we are - Personality and social factors

Recent research shows that music preferences can be summarized by four dimensions and these dimensions are associated with certain personality characteristics, analyzed according to the five factor theory of personality. However, when directly asked to describe listeners of different musical genres, respondents make limited reference to personality characteristics. When classification of musical genres familiar to university students in Turkey by factor analysis and by judgments of similarity are compared, five main groups emerge. One group, which may be similar to the “folk” dimension that emerged in some studies with west European samples although it was missing in the North American data, subsumes styles indigenous to Turkey. Some styles such as techno, underground, blues, Turkish art music and another Turkish genre called Arabesk are classified differently depending on the method used. The comparison of personality profiles with perceived qualities of genres and their listeners do show some consistencies but some styles that appear similar may appeal to very different kinds of persons. Studying the relationship between music preferences and person variables would benefit from including a variety of measures, different cultures, and both target person and perceiver perspectives.
ORIGINALNI NAUČNI RAD PREEXERCISE SUPEROXIDE DISMUTASE ACTIVITY AFFECTS THE PRO / ANTIOXIDANT RESPONSE TO ACUTE EXERCISE

Superoksid dismutaza (SOD), prva linija antioksidativnog zaštitnog sistema, enzim je koji je u prethodnim istraživanjima bio najpodložniji promenama usled uticaja trenažnog procesa. Ovaj enzim je takođe bio onaj po kom su se dobro utrenirani i netrenirani ispitanici istraživanja razlikovali. Cilj naše studije bio je utvrđivanje razlike u odgovoru parametara redoks ravnoteže na jednokratno fi zičko vežbanje kod ispitanika sa različitom bazalnom aktivnosti SOD. 24 mlada rukometaša podvrgnuta su maksimalnom progresivnom testu opterećenja. Neposredno pre i nakon testa opterećenja ispitanicima su uzeti uzorci krvi, radi biohemijske analize parametara redoks ravnoteže – u plazmi je određivan nivo superoksid anjon radikala (O2-), hidrogen peroksida (H2O2), azotnog monoksida (NO, određivanog preko nitrita NO2-), indeksa lipidne peroksidacije (TBARS), a u eritrocitima aktivnost superoksid dismutaze (SOD) i katalaze (CAT). Jednokratno vežbanje izazvalo je statistički značajne promene svih praćenih parametara, osim O2-, a najznačajnije promene uočene su u grupi ispitanika sa najnižom bazalnom aktivnosti SOD. Značajnije korelacije pronađene su između bazalne aktivnosti SOD i H2O2, i SOD i NO (NO2-). Ovi rezultati navode nas na zaključak da bazalna aktivnost SOD određuje efekte vežbanja na redoks ravnotežu. Ključne reči: oksidativni stres, redoks ravnoteža, superoksid dismutaza, sportisti, vežbanje. ABSTRACT
A Ray-Optics Approach for Evaporation Duct Channel Modeling

In this paper, a three-stage ray optics (RO)-based modeling approach is proposed to characterize the maritime evaporation duct channel. The channel model follows the classic form which is a superposition of multipath components (MPC), while each MPC corresponds to an arrived ray identified by the RO method. We propose an algorithm to search for all feasible rays, with which important statistical channel parameters, such as the number of rays, reflection times, trajectory lengths, angles of departure/arrival, can be efficiently obtained. The proposed channel model is validated by comparing with the conventional parabolic equation-based approach. Large- and small-scale fad- ing characteristics of the duct channel are also analyzed and discussed based on the proposed model.
Partial inhibition of flowering in young highbush blueberries with gibberellins

W. Lindberg, E. Hanson, and G.A. Lobos. 2014. Partial inhibition of flowering in young highbush blueberries with gibberellins. Cien. Inv. Agr. 41(3):349-356. Preventing young blueberry (Vaccinium corymbosum L.) plants from fruiting can increase their vegetative growth. In previous studies, gibberellin (GA) applications reduced flowering in highbush blueberry, but the response was variable and cultivar dependent and was studied mostly using potted nursery plants. The purpose of this work was to determine whether floral induction can be inhibited by GA in plants established in the field, particularly on newer cultivars now being widely planted. Foliar sprays were applied in several experiments with different application intervals and concentrations; the efficacy was determined by counting the number of initiated floral meristems. GA applications in July and August were more inhibitive than those in September and October, while cultivars did not vary in their response. GA significantly reduced flower bud numbers in three separate studies, but the greatest reduction (49%) required repeated applications from July to October. The results indicate that GA may have limited commercial utility for preventing fruiting in highbush blueberries under field conditions. However, further studies are needed to determine how vegetative growth is affected by the partial inhibition of flowering.

These populations are separated using transformations based on mathematical morphology. Size measurements (equivalent diameter) enable the analysis of the mechanisms through comparison with growth models. Microsc. Microanal. Microstruct. 7 (1996) OCTOBER/DECEMBER 1996, PAGE 387
Supply chain design approaches for supply chain resilience: A qualitative study of South African fast-moving consumer goods grocery manufacturers

Orientation: In today’s globalised and complex business environment, firms are ever more vulnerable to supply chain disruptions, originating both internally and externally from the supply chain. Supply chain resilience minimises the impact of a disruption through design approaches, which allows the supply chain to respond appropriately to disruptive events. Research purpose: This article investigated the supply chain risks faced by grocery manufacturers in the South African fast-moving consumer goods (FMCG) industry and explored supply chain design approaches that enable supply chain resilience. Motivation for the study: South African grocery manufacturers are faced with distinct risks. Whilst supply chain risk management studies have provided firms with certain guidelines to mitigate risk, supply chains are still vulnerable to unanticipated risks. Literature on supply chain resilience in the South African context is scant. The concept of supply chain resilience provides firms with strategies that are built into the supply chain that allow firms to react and recover swiftly from disruptions. Furthermore, supply chain resilience strategies assist firms in becoming less vulnerable to possible disruptions. Research design approach and method: This study was conducted by using a descriptive qualitative research design. Data were collected through semi-structured interviews with senior supply chain practitioners specifically within the South African FMCG grocery manufacturing industry. Main findings: The study found that labour unrest is the most common risk faced by the industry. Furthermore, strategic stock and supply chain mapping are of the most useful design approaches to enhance supply chain resilience. Practical/managerial implications: The study provides managers with new insights in guiding supply chain design decisions for resilient supply chains. Through the identification of risks and appropriate solutions linked to the various risks, the study allows managers an array of options to choose from when enforcing a resilient supply chain. Contribution/ value-add: The study contributes to the body of knowledge by being one of the first empirical studies conducted on supply chain design approaches for supply chain resilience in the South African context. The study also adds to the scarce literature on supply chain resilience in the FMCG industry, both globally and in a South African context.
A diallel cross analysis of heading date in wheat.

A complete diallel cross of 10 selected wheat varieties was grown for three years (1957-1959) at Davis, California, to determine whether genetic information useful in the breeding of self-pollinated plants could be obtained from parental and F1 data. The character studied was heading date. Analysis of the data indicated that a few major genes with dominance effects were the most important feature of the genetic system. A system of minor genes displaying little or no dominance was also discovered. There was no evidence for any important epistatic effects. The various genotypes were found to behave fairly similarly over the three-year period. Variances and frequency distributions observed in 7 F2 test populations and certain other segregating generations grown in 1958 corresponded closely in most cases to those predicted on the basis of the 1957 diallel cross analysis.

Reliability of Rebound Hammer Test in Concrete Compressive Strength Estimation

The reliability of the non-destructive Schmidt Hammer Test as a means of estimating the compressive strength of concrete is investigated by testing three groups of concrete cube specimens. The first group was exposed to cycles of alternate drying and wetting in brackish water; the second group, to continuous immersion in brackish water; and the third (control) group, to normal room condition. Results show that the average Schmidt Hammer Rebound Number (RN) for samples in the first and second group is significantly less than that of the third group. These indicate the reliability of the Schmidt Hammer Test in predicting the reducing effect of exposure to brackish water on the compressive strength of concrete. Moreover, results show that in each of the three groups, the average estimated compressive strength of concrete based on Schmidt Hammer Test (using the rebound curve provided by the manufacturer of the device) underestimates the average actual compressive strengths based on direct compression test. Thus, in a quick strength and safety assessment of existing concrete structures, the Schmidt Hammer Test is fairly reliable in determining whether the further use of the structure would still be safe, but may not be so in concluding whether the use is no longer safe. In the latter case, the Schmidt Hammer Test should be supplemented by core sampling and testing. O determine the strength of concrete in existing structures, cylinder specimens are usually taken from the structures and brought to laboratories where they are loaded to failure to obtain actual compressive strength. This procedure is the most accurate way but it requires considerable time and expenses. In order to assess in-situ concrete strength in a faster manner, non-destructive testing (NDT) techniques have been developed and adopted. These techniques estimate the strength of existing structures by measuring some concrete properties other than its strength, and then relate these properties to strength or other mechanical properties of concrete (1). Among the many available NDT techniques, the most widely employed is the one using a device called the rebound hammer, also known as the Schmidt Hammer, due to the
Three’s Company: An Additional Non-transiting Super-Earth in the Bright HD 3167 System, and Masses for All Three Planets

HD 3167 is a bright (V = 8.9), nearby K0 star observed by the NASA K2 mission (EPIC 220383386), hosting two small, short-period transiting planets. Here we present the results of a multi-site, multi-instrument radial-velocity campaign to characterize the HD 3167 system. The masses of the transiting planets are 5.02 ± 0.38 for HD 3167 b, a hot super-Earth with a likely rocky composition ( = g cm−3), and for HD 3167 c, a warm sub-Neptune with a likely substantial volatile complement ( = g cm−3). We explore the possibility of atmospheric composition analysis and determine that planet c is amenable to transmission spectroscopy measurements, and planet b is a potential thermal emission target. We detect a third, non-transiting planet, HD 3167 d, with a period of 8.509 ± 0.045 d (between planets b and c) and a minimum mass of 6.90 ± 0.71 . We are able to constrain the mutual inclination of planet d with planets b and c: we rule out mutual inclinations below 1. °3 because we do not observe transits of planet d. From 1. °3 to 40°, there are viewing geometries invoking special nodal configurations, which result in planet d not transiting some fraction of the time. From 40° to 60°, Kozai–Lidov oscillations increase the system’s instability, but it can remain stable for up to 100 Myr. Above 60°, the system is unstable. HD 3167 promises to be a fruitful system for further study and a preview of the many exciting systems expected from the upcoming NASA TESS mission.
