A minute ostracod (Crustacea: Cytheromatidae) from the Miocene Solimoes Formation (western Amazonia, Brazil) evidence for marine incursions?
Venue: Journal of systematic palaeontology

A huge wetland (the 'Pebas system' covered western Amazonia during the Miocene, hosting a highly diverse and endemic aquatic fauna. One of the most contentious issues concerns the existence, potential pathways and effects of marine incursions on this ecosystem. Palaeontological evidences (body fossils) are rare. The finding of a new, presumably marine ostracod species (Pellucistoma curupira sp. nov. in the upper middle Miocene Solimoes Formation initiated a taxonomic, ecological and biogeographical review of the genus Pellucistoma. We demonstrate that this marine (sublittoral, euhaline) subtropical tropical taxon is biogeographically confined to the Americas. The biogeographical distribution of Pellucistoma largely depends on geographical, thermal and osmotic barriers (e.g. land bridges, deep and/or cold waters, sea currents, salinity) We assume an Oligocene/early Miocene, Caribbean origin for Pellucistoma and outline the dispersal of hitherto known species up to the Holocene. Pellucistoma curupira sp. nov. is dwarfed in comparison to all other species of this genus and extremely thin shelled. This is probably related to poorly oxygenated waters and, in particular, to strongly reduced salinity. The associated ostracod fauna (dominated by the eurypotent Cyprideis and a few, also stunted ostracods of possibly marine ancestry) supports this claim. Geochemical analyses (d18O, d13C) on co occurring ostracod valves (Cyprideis spp. yielded very light values, indicative of a freshwater setting. These observations point to a successful adaptation of P. curupira sp. nov. to freshwater conditions and therefore do not signify the presence of marine water. Pellucistoma curupira sp. nov. shows closest affinities to Caribbean species. We hypothesize that Pellucistoma reached northern South America (Llanos Basin) during marine incursions in the early Miocene. While larger animals of marine origin (e.g. fishes, dolphins, manatees) migrated actively into the Pebas wetland via fluvial connections, small biota (e.g. P. curupira sp. nov. were phoretically freighted and developed freshwater tolerance over long timescales. http:/zoobank.org/urn:lsid:zoobank.org:pub:886C6476 393D 4323 8C0E 06BB8BD02FD9
The genus Perissocytheridea Stephenson, 1938 (Crustacea: Ostracoda) and evidence of brackish water facies along the Oligo Miocene, Pirabas Formation, eastern Amazonia, Brazil

Perissocytheridea Stephenson is characteristic of brackish water facies. In 57 samples from the Upper Oligocene to Lower Miocene, from five localities, Pirabas Formation, Para State, Brazil eleven species have been identified. Among these species, four are new reports: Perissocytheridea punctoreticulata n. sp. Perissocytheridea largulateralis n. sp. Perissocytheridea colini n. sp. and Perissocytheridea pirabensis n. sp. five species in open nomenclature: Perissocytheridea sp. 1, P. sp. 2, P. sp. 3, P sp. 4, and P. sp. 5 and two species left in "aff."  Perissocytheridea aff. Perissocytheridea pumila and Perissocytheridea aff. Perissocytheridea brachyforma subsp.  The distributional pattern of the Perissocytheridea combined with the occurrence of foraminifera Elphidium and Ammonia in the studied sections supports the presence of the brackish water facies to the respective layers. Their quantitative variation through the studied sections indicate more than one phase of salinity reduction (about >5 and
Angle of arrival (AoA) estimation by using software defined radios
Venue: 2016 24th Signal Processing and Communication Application Conference (SIU)

Source direction of arrival (DoA) or angle of arrival (AoA) estimation is one of the vital problems in many wireless communication applications such as radar, radio astronomy, sonar and navigation. The resolution of a source direction of arrival estimation can be improved by an uniform linear array (ULA) system with innovative signal processing techniques. Super resolution techniques take the advantage of linear array antenna structures to better process the incoming waves. These techniques also have the ability to describe the direction of multiple targets. In this paper, MUSIC algorithm is implemented on USRP nodes using LabVIEW platform. Four receiver antennas are used to detect the AoA of a single carrier and unmodulated RF signal at 2.45 GHz in an indoor environment. The experimental results are shown for a single source which is tested at two different arbitrary angles to confirm the real time implementation of MUSIC algorithm with some errors which occur due to lack of some hardware imperfections. Moreover, these hardware imperfections are studied.
Managing Conflict between Engineers/R&D and Marketers in New Product Development Process

This article is a literature review which involves conflict between engineer/research development (R&D) specialists and marketers. Such conflict often occurs during new product development (NPD) process due to the differences in knowledge background, personality, and working styles of the two parties. There are 3 types of conflict, consisting of 1) task conflict emerging from the argument and discussion on NPD issues, 2) process conflict emerging from misunderstanding of own duties during NPD, and 3) relationship conflict emerging from dissatisfaction or interpersonal animosity of the integration. Managing these types of conflict can be done in many styles, which includes 1) integrating 2) obliging 3) compromising 4) dominating, and 5) avoiding. Each style is implemented based on individual working characteristics. kaarbrhaarkhwaamkhdaeyngrahwaangwswkr/nkwcchyaelaphthnaaaelankkaartlaad ainkrabwnkaarphthnaaphltphnthaihm bthkhwaamnepnkaarthbthwnwrrnkrrmthekywkh`ngkbkhwaamkhdaeyngrahwaangwswkr/nkwcchyaelaphthnaa aela nkkaartlaad chngmkekdkhnb`ykhrngainkrabwnkaarphthnaaphltphnth en`ngcchaakkhwaamaetktaangdaanphnthaankhwaamr bkhlkphaaphaelarpaebbkaarthamngaankh`ngthngs`ngfaay khwaamkhdaeyngsaamaarthekdkhnaid 3 rpaebb aidaek 1) khwaamkhdaeyngainngaan chngekdcchaakkaarotaeynghr`thkethyngainpraednthekywkh`ngkbngaanphthnaaphltphnth 2) khwaamkhdaeyngainkrabwnkaar chngekdcchaakkhwaamaimekhaaaicchbthbaathkh`ngtne`ngainchwngkaarprbeplynkrabwnkaarthamngaan aela 3) khwaamkhdaeyngswntw chngekdcchaakkhwaamaimph`aicchhr`m`khtt`bkhkhltht`ngthamngaanrwmkn chngkaarbrhaarkhwaamkhdaeyngthngsaampraephthnsaamaarthkrathamaidhlaayrpaebb aidaek 1) kaarekhaarwm 2) kaary`mtaam 3) kaarpranpran`m 4) kaarekhaakhm aela 5) kaarhlkelyng odyaetlarpaebbcchaekdkhntaamlksnakaarthamngaankh`ngaetlakhn
Monthly swelling of the knee Case report and review of the literature.
Venue: The Knee

We report a 17 year old with monthly swelling of her knee. The complaints are associated with the menstrual cycle. After physical examination, radiographs, MRI and an arthroscopy with biopsies, a diagnosis of intra articular endometriosis and menstrual arthritis was made.  Both an intra articular manifestation of endometriosis and menstrual arthritis are very rare diagnoses. Extraperitoneal lesions of endometriosis are rare and the mechanism for spreading outside the retroperitoneal space is unknown. A similar situation exists for menstrual arthritis, it is thought that cytokines, which are produced as a reaction to retrograde menstruation, are the trigger for menstrual arthritis. A review of literature is given.  A monthly recurrent, painful swelling of a joint, can and should give rise to thorough investigation. Differential diagnostic one should think of intra articular manifestation of endometriosis and menstrual arthritis. We give a proposal for treatment.
An unusual case of a massive intra articular angiolipoma of the knee Case report and review of literature

We report a case of a 59 year old woman who presented with new onset knee pain after starting an exercise program. Clinical examination pointed to a possible lateral meniscal tear. This was confirmed radiologically, but an intra articular mass suspected to be a lipoma was also found on MRI. Excision biopsy was done and diagnosis was confirmed histologically. To the best of our knowledge, this is the case with the largest intra articular knee angiolipoma reported till date. The differentiation between this type of mass and other more common encountered conditions, like lipoma arborescens and Hoffa's syndrome, is discussed.
Unique three dimensional architecture using a metal free semiconductor cross linked bismuth vanadate for efficient photoelectrochemical water oxidation

In this study, we report a unique design of nano porous bismuth vanadate (BiVO 4 photoelectrode decorated with graphene linked carbon nitride (GCN) nanosheets and their potential application in solar driven photoelectrochemical water oxidation. Especially, an integrated sandwich like heterojunction with highly interconnected porous structure, comprising two dimensional GCN sheets and three dimensional BiVO 4 was successfully synthesized with significantly enhanced photoelectrochemical activity. The prepared photoelectrode achieves up to 1.98 mA cm 2 (1.23 V vs RHE) under AM 1.5G solar light irradiation, 2.06 times compared with pristine BiVO 4 (0.96 mA cm 2 at 1.23 V vs RHE) After deposition of cobalt phosphate nanoparticles as water oxidation electrocatalyst, a plateau photocurrent of 3.42 mA cm 2 (1.23 V vs RHE) with a maximum photo conversion efficiency of 1.28% was achieved on the prepared photoanode. The highly improved photoelectrochemical performance can be attributed to suitable band matching facilitating efficient charge separation between GCN and BiVO 4 as well as the desirable incorporation of rational designed dimensionality dependent heterojunction for promoted solar energy utilization. More importantly, the combined experimental results and computational simulations reveal that the strong donor acceptor coupling between GCN sheets and porous BiVO 4 facilitates the separation and transfer of photoinduced electron hole pairs, accounting for the highly promoted photoelectrochemical performance.
Overview of business innovations and research opportunities in blockchain and introduction to the special issue

Blockchain has become a new frontier of venture capitals that has attracted the attention of banks, governments, and other business corporations. The recent blockchain related attempts included legal blockchains by Fadada.com and Microsoft and pork tracking blockchains by Walmart and IBM. Blockchain is poised to become the most exciting invention after the Internet; while the latter connects the world to enable new business models based on online business processes, the former will help resolve the trust issue more efficiently via network computing. In this paper, we give an overview on blockchain research and development as well as introduce the papers in this special issue. We show that while blockchain has enabled Bitcoin, the most successful digital currency, its widespread adoption in finance and other business sectors will lead to many business innovations as well as many research opportunities.
Non rigid Object Tracking Using Modified Mean Shift Method

The traditional Mean Shift algorithm uses a single histogram to tracking moving objects. Because the traditional Mean Shift lacks spatial distribution information, so it is difficult to track non rigid object especially. With a focus on this problem, an improved Mean Shift algorithm based on the shape feature and color of the target is presented. The results show that the algorithm can track the non rigid target in real time, and it has a preferable adaptability and robustness to the irregular motion and deformation of the target.
Real time Tracking of Non rigid Objects
Venue: ICCIS '16

Currently, pose variations and irregular movements are the main constraints in the tracking of the non rigid object. In order to avoid the inaccurate location or the failure of tracking the non rigid object, a novel tracking method combining particle filter and Mean Shift algorithm is proposed. The motion segmentation is used to correct particle filter's estimation error of the non rigid target, which improves the efficiency, as well as the robustness of the algorithm against noises. The normalized correlation coefficient is calculated to determine whether to update the template of Mean Shift algorithm. We also test the algorithm on the open popular datasets. Results prove that the algorithm presented in this work shows better results in both aspects of effectiveness and efficiency than the method combining CAMShift algorithm with Kalman filter.

Distributed Subgradient Algorithm for Multi Agent Convex Optimization with Global Inequality and Equality Constraints

In this paper, we present an improved subgradient algorithm for solving a general multi agent convex optimization problem in a distributed way, where the agents are to jointly minimize a global objective function subject to a global inequality constraint, a global equality constraint and a global constraint set. The global objective function is a combination of local agent objective functions and the global constraint set is the intersection of each agent local constraint set. Our motivation comes from networking applications where dual and primal dual subgradient methods have attracted much attention in the design of decentralized network protocols. Our main focus is on constrained problems where the local constraint sets are identical. Thus, we propose a distributed primal dual subgradient algorithm, which is based on the description of the primal dual optimal solutions as the saddle points of the penalty functions. We show that, the algorithm can be implemented over networks with changing topologies but satisfying a standard connectivity property, and allow the agents to asymptotically converge to optimal solution with optimal value of the optimization problem under the Slater's condition.

YTHDF2 destabilizes m6A containing RNA through direct recruitment of the CCR4 NOT deadenylase complex
Venue: Nature communications

Methylation at the N6 position of adenosine (m6A) is the most abundant RNA modification within protein coding and long noncoding RNAs in eukaryotes and is a reversible process with important biological functions. YT521 B homology domain family (YTHDF) proteins are the readers of m6A, the binding of which results in the alteration of the translation efficiency and stability of m6A containing RNAs. However, the mechanism by which YTHDF proteins cause the degradation of m6A containing RNAs is poorly understood. Here we report that m6A containing RNAs exhibit accelerated deadenylation that is mediated by the CCR4 NOT deadenylase complex. We further show that YTHDF2 recruits the CCR4 NOT complex through a direct interaction between the YTHDF2 N terminal region and the SH domain of the CNOT1 subunit, and that this recruitment is essential for the deadenylation of m6A containing RNAs by CAF1 and CCR4. Therefore, we have uncovered the mechanism of YTHDF2 mediated degradation of m6A containing RNAs in mammalian cells.
The Impact of Project Manager on Project Success The Case of ICT Sector

The project management literature on project success is rich. Numerous papers focus on the evolution of the understanding of project success, identification of success criteria and critical success factors. Critical success factors increase the potential for achieving project success, while project success can be evaluated with the help of success criteria. Although the interrelationships between critical success factors and success criteria are rarely analyzed, yet there is a strong demand for it. The aim of this paper is twofold. One of the aims is to identify the impact of one of the critical success factors, the project manager's project management attitude on project success. The other aim is to highlight the interrelationship between the project manager's personal characteristics and project management attitude and leadership style, which are three critical success factors. These aim to address the shortcoming mentioned above, which is considering the lack of the interrelationships between critical success factors and success criteria. The research outcomes are drawn from qualitative field research at the Hungarian subsidiaries of multinational companies operating in the ICT sector.
Adopting Agile software development: the project manager experience
Venue: Inf. Technol. People

Early research into Agile approaches explored particular practices or quantified improvements in code production. Less well researched is how Agile teams are managed. The project manager (PM) role is traditionally one of "command and control" but Agile methods require a more facilitative approach. How this changing role plays out in practice is not yet clearly understood. The purpose of this paper is to provide insight into how adopting Agile techniques shape the working practices of PMs and critically reflect on some of the tensions that arise.  An ethnographic approach was used to surface a richer understanding of the issues and tensions faced by PMs as Agile methods are introduced. Ethnographic fiction conveys the story to a wider audience.  Agile approaches shift responsibility and spread expert knowledge seeming to undermine the traditional PM function. However, the findings here show various scenarios that allow PMs to wrest control and become more of a "gate keeper" Ethnographic fiction communicates a sense of the PMs frustration with the conflict between the need to control and the desire for teams to take more responsibility.  Stories provide insight and communicate the experiential feel behind issues faced by PMs adopting Agile to surface useful knowledge. The objective is not how to measure knowledge, but how to recognize it. These reflections are valuable to fellow researchers as well as practitioners and contribute to the growing literature on Agile project management.
Lessons for IT Project Manager Efficacy: A Review of the Literature Associated with Project Success

In the maturing IT project management space, there are still many debates about the skills needed to achieve success. This article presents a review and synthesis of project management literature that highlights the potential conflict in goals and the measurement of "success" from three perspectives: project outcomes, project management processes, and the project manager's influence. Our review indicates that each perspective of success, defined by various stakeholders at various points in time, shifts the focus onto different skills and knowledge. Drawing upon this tri focal lens, we propose a shift in focus on success to the intersection, or "sweet spot of project manager efficacy."
