—Initial uplink synchronization is an integral part of the wireless communication systems. It enables the base station (BS) to detect new subscriber stations (SS) willing to commence communication. It also enables the BS to estimate the uplink channel parameters of these SSs. Accurate estimation of channel parameters is crucial, as they ensure the uplink signals from all the SSs arrive at the BS synchronously at similar power levels. However, this detection and estimation problem turns out to be very challenging when multiple users initiate the synchronization procedure at the same time. We address this issue by exploiting the underlying sparsity of the estimation problem. We propose a fast sparse signal recovery approach that shows a clear improvement in detection and estimation performance compared to other state of the art methods. The proposed method can be integrated into any OFDM based standard.
A NEW CHANNID (TELEOSTEI: CHANNIFORMES) FROM THE EOCENE AND OLIGOCENE OF EGYPT

Abstract Upper Eocene and lower Oligocene deposits of the Jebel Qatrani Formation, Fayum Depression, Egypt, have provided a number of skulls and other bones that belong to a species of snakehead (Channidae). This material is morphologically more similar to species of Parachanna, rather than species of Channa, and is here described as a new species, Parachanna fayumensis. It differs from the other species of the genus in possessing a prominent tooth patch on the posterior end of the parasphenoid. This new species of channid is the oldest member of the family known from Africa. Prior to this record, the oldest African fossil channid material was found in Mio–Pliocene deposits. This lack of information on the African fossil record leads to biogeographic reconstructions in which channids were believed to have arisen in Asia and invaded Africa through fresh waters, only after the two continents were connected in the Miocene. The Egyptian material shows that channids were in the fresh waters of Africa in the latest Eocene. Either a freshwater connection existed between Africa and Asia before or during the late Eocene, or members of the Channidae were able to migrate through marine waters to attain their current distribution.
Lightweight human activity recognition for ambient assisted living

—Ambient assisted living (AAL) systems aim to improve the safety, comfort, and quality of life for the populations with specific attention given to prolonging personal independence during later stages of life. Human activity recognition (HAR) plays a crucial role in enabling AAL systems to recognise and understand human actions. Multi-view human activity recognition (MV-HAR) techniques are particularly useful for AAL systems as they can use information from multiple sensors to capture different perspectives of human activities and can help to improve the robustness and accuracy of activity recognition. In this work, we propose a lightweight activity recognition pipeline that utilizes skeleton data from multiple perspectives to combine the advantages of both approaches and thereby enhance an assistive robot’s perception of human activity. The pipeline includes data sampling, input data type, and representation and classification methods. Our method modifies a classic LeNet classification model (M-LeNet) and uses a Vision Transformer (ViT) for the classification task. Experimental evaluation on a multi-perspective dataset of human activities in the home (RH-HAR-SK) compares the performance of these two models and indicates that combining camera views can improve recognition accuracy. Furthermore, our pipeline provides a more efficient and scalable solution in the AAL context, where bandwidth and computing resources are often limited.

(2017). An accurate and flexible calorimeter topology for power electronic system loss measurement. In 2017 IEEE International Electric Machines and Drives

—The drive to improve power electronic system ef-ﬁciencies makes the accurate and repeatable determination of power losses ever more important. As operating frequencies, harmonic content and efﬁciency increase, electrical methods of measuring loss become more uncertain since they are affected by phase-errors and electromagnetic interference among other factors. Alternative calorimetric methods allow system losses, which manifest as heat, to be measured directly with a high degree of accuracy. However, calorimeter facilities tend to be costly bespoke measurement systems which is a barrier to their widespread use. In this paper, an extension to the closed double-jacket type calorimeter topology is presented which offers comparatively low-cost, simpliﬁed construction and improved ﬂexibility with the aim of promoting a more widespread use of calorimetry within the power electronics community.
and Clinical Outcome Diverters: Midterm Angiographic Evolution Aneurysms Treated by Extrasaccular Flow Middle Cerebral Artery Bifurcation

BACKGROUNDANDPURPOSE: Flowdivertershavebeenincreasinglyusedlatelyinoff-label,distalintracranialaneurysmtreatments.Our aim was to evaluate the effectiveness of ﬂow diverters in the treatment of middle cerebral artery bifurcation aneurysms and to analyze midterm angiographic patterns of regional ﬂow modiﬁcations for safety and clinical outcomes. MATERIALS AND METHODS: Consecutive patients treated from January 2010 to December 2014 by the authors by using endovascular ﬂow-diverting stents for MCA bifurcation aneurysms were evaluated retrospectively with prospectively maintained data. All patients had been followed for at least 12 months after treatment, with at least 2 control angiograms; regional ﬂow-related angiographic modiﬁcations were registered by using a new angiographic outcome scale for ﬂow diverters. Data were analyzed with emphasis on procedure-related events, angiographic results, and clinical outcome. RESULTS: Fifty-eight patients were included in the study, with 63 MCA bifurcation aneurysms; 13 of these were large and giant. Pretreatment mRS was 0 for 12 patients (20.7%), 1 for 41 (70.7%), and 2 for 5 patients (8.6%). Six-month control revealed mRS 0–2 for 57 (98.3%) patients and 3 for 1 (1.7%) patient. Procedure-related morbidity and mortality were 8.6% (5/58) and 0%, respectively. From 95% of still circulating immediate postprocedure angiographic outcomes, 68% progressed to aneurysm occlusion at 6 months and 95%, to occlusion at 12 months, with a 0% aneurysm rupture rate. CONCLUSIONS: Flow diverters seem to be an effective treatment alternative for complex MCA bifurcation aneurysms, with reasonable complication rates. Longer angiographic follow-ups are needed to assess the morphologic outcome; immediate subtotal occlusions do not seem to be related to rupture.
The Bacteroides sp. 3_1_23 Pif1 protein is a multifunctional helicase

ScPif1 DNA helicase is the prototypical member of a 5′-to-3′ helicase superfamily conserved from bacteria to human and plays various roles in the maintenance of genomic homeostasis. While many studies have been performed with eukaryotic Pif1 helicases, including yeast and human Pif1 proteins, the potential functions and biochemical properties of prokaryotic Pif1 helicases remain largely unknown. Here, we report the expression, purification and biochemical analysis of Pif1 helicase from Bacteroides sp. 3_1_23 (BsPif1). BsPif1 binds to a large panel of DNA substrates and, in particular, efficiently unwinds partial duplex DNAs with 5′-overhang, fork-like substrates, D-loop and flap-like substrates, suggesting that BsPif1 may act at stalled DNA replication forks and enhance Okazaki fragment maturation. Like its eukaryotic homologues, BsPif1 resolves R-loop structures and unwinds DNA–RNA hybrids. Furthermore, BsPif1 efficiently unfolds G-quadruplexes and disrupts nucleoprotein complexes. Altogether, these results highlight that prokaryotic Pif1 helicases may resolve common issues that arise during DNA transactions. Interestingly, we found that BsPif1 is different from yeast Pif1, but resembles more human Pif1 with regard to substrate specificity, helicase activity and mode of action. These findings are discussed in the context of the possible functions of prokaryotic Pif1 helicases in vivo.
Inequality Aversion and Risk Attitudes

Using self reported measures of life satisfaction and risk attitudes, we empirically test whether there is a relationship between individuals inequality and risk aversion. The empirical analysis uses the German SOEP household panel for the years 1997 to 2007 to conclude that the negative effect of inequality measured by the sample gini coefficient by year and federal state is larger for those individuals who report to be less willing to take risks. Nevertheless, the empirical results suggest that even though inequality and risk aversion are related, they are not the same thing. The paper shows that the relationship between risk attitudes and inequality aversion survives the inclusion of individual characteristics (i.e. income, education, and gender) that may be correlated with both risk attitudes and inequality aversion.
Journal of Advances in Applied & Computational Mathematics

Convex analysis is a discipline of mathematics dedicated to the explication of the properties of convex sets and convex functions. Convex functions are extremely useful in proving many famous inequalities in mathematics. It is widely known that inequalities defined by convex functions originated with the works done by Holder and Jensen among others and applied to modeling a variety of problems both in hard and soft sciences. It is said that the arsenal of an analyst is heavily stocked with inequalities. Studies related to convexity have kept occupying a central position in almost all areas of mathematics, especially in functional analysis and operations research. Following the emergence of fuzzy set theory, fuzzy convexity alongside a number of related concepts has been explicated. However, not much has been done regarding fuzzy inequalities defined by fuzzy convexity. In this paper, a novel attempt to study arithmetic mean-geometric mean is proposed. In this short note, we provide two proofs of the arithmetic mean-geometric mean inequality for convex fuzzy sets.

The paper reviews groundwater recharge and drainage in Shijiazhuang plain areas, as well as the main geological disasters caused thereby. Some factors influencing groundwater funnels at these areas were analyzed to be able to suggest control precautions. For the sustainable development some preventive predictions and restorability considerations were carried out to suggest some solutions for dealing with the problem of water shortage in these areas.
Dynamic Provisioning: A Countercyclical Tool for Loan Loss Reserves

In the wake of the financial crisis of 2007-2009, as various banking policymakers revisit loan loss provisioning rules, the Spanish approach of dynamic provisioning has garnered attention as a potential alternative to the current incurred loss approach. We review the current approach to loan loss reserves in the United States, focusing on how loan loss reserves relate to bank solvency and why the current accounting approach may have procyclical effects. We present a conceptual framework to compare loan loss provisioning under the incurred loss framework and dynamic provisioning. Then we simulate dynamic provisioning with U.S. data to present an empirical comparison.
Search for anomalous electroweak production of $WW/WZ$ in association with a high-mass dijet system in $pp$ collisions at $\sqrt{s}=8$ TeV with the ATLAS detector

A search is presented for anomalous quartic gauge boson couplings in vector-boson scattering. The data for the analysis correspond to $20.2$ fb$^{-1}$ of $\sqrt{s}=8$ TeV $pp$ collisions, and were collected in 2012 by the ATLAS experiment at the Large Hadron Collider. The search looks for the production of $WW$ or $WZ$ boson pairs accompanied by a high-mass dijet system, with one $W$ decaying leptonically, and a $W$ or $Z$ decaying hadronically. The hadronically decaying $W/Z$ is reconstructed as either two small-radius jets or one large-radius jet using jet substructure techniques. Constraints on the anomalous quartic gauge boson coupling parameters $\alpha_4$ and $\alpha_5$ are set by fitting the transverse mass of the diboson system, and the resulting 95% confidence intervals are $-0.024<\alpha_4<0.030$ and $-0.028<\alpha_5<0.033$.
Optimal learning on climate change : Why climate skeptics should reduce emissions

Climate skeptics typically argue that the possibility that global warming is exogenous, implies that we should not take additional action towards reducing emissions until we know what drives warming. This paper however shows that even climate skeptics have an incentive to reduce emissions: such a directional change generates information on the causes of global warming. Since the optimal policy depends upon these causes, they are valuable to know. Although increasing emissions would also generate information, that option is inferior due its irreversibility. We show that optimality can even imply that climate skeptics should actually argue for lower emissions than believers. & 2014 Elsevier Inc. All rights reserved.
Worldviews Apart: Agricultural Extension and Ethiopian Worldviews Apart: Agricultural Extension and Ethiopian Smallholder Farmers Smallholder Farmers

This paper presents an inquiry-based learning assessment into why farmers in the highlands of Ethiopia were not adopting a new planting methodology promoted by the government and non-governmental organizations. It offers a process of reflexivity whereby assumptions emerge as the key barriers to misunderstanding, and focuses on the concept of divergent worldviews as an important consideration for understanding (non)adoption. The learning process offers insight for policy, programming and research, emphasizing learning instead of definitive conclusions
University of Birmingham From Mao to McDonaldization? Assessing the rationalisation of health care in China

China's 2009 health care reform agenda has been referred to as one of the most ambitious health policy programmes in modern history. Significant investment has combined with new structures, incentives, and regulations that have aimed to improve access, as well as gain greater con-trol over a health care market much criticised for putting profit before patients. A range of health services research has been undertaken to analyse these efforts. Sociological perspectives have also been documented yet up to now a review and synthesis combining these various contributions has not been undertaken. By drawing on the lens of McDonaldization, the paper presents a narrative review that analyses the extent to which China's 2009 reform agenda has increased efficiency, calculability, predictability, and control over service provision. The review identifies elements of McDonaldization within China's 2009 reform agenda, however, notable gaps remain. In response to the limits of McDonaldization as a lens for understanding China's health care reform, the paper calls for alternative perspectives that are better able to understand the sociocultural dynamics shaping service provision, as well as an interdisciplinary research agenda that is able to generate new insights and understanding regarding health care in China.
Study on Snowline and Climate Changes during Different Ice Ages in the Qilian Mountains since Pleistocene

In this paper,the degressive altitude of snowline and the corresponding change of temperature and precipitation in the Qilian Mountains during five ice ages since Pleistocene are lucubrated.The results are as follows:(1) The degressive altitude of snowline in the Qilian Mountains was decreased from the earliest ice age to the latest ice age,which reveal that the snowline altitude has been continuously increased and the glacier size has been reduced under global climate change since Pleistocene;(2) Change of snowline is closely related to the change of precipitation and temperature,for example,the degressive altitude of snowline in the mountains during the third ice age from now was the most significant because of the low temperature and more precipitation,whereas the size of glaciers during the second ice age from now did not exceed that during the third ice age from now under lower temperature but less precipitation;(3) It is considered that the periodical change of solar radiation is the main cause resulting in climate change and alternation of ice ages and interglacial ages.Moreover,the uplift of the Qinghai-Tibetan Plateau brings about the changes the atmospheric circulation,temperature and precipitation as well as snowline,so it is also an important factor affecting climate and snowline changes.
Free Radical Biology and Medicine

Imbalances in the oral microbial community have been associated with reduced cardiovascular and metabolic health. A possible mechanism linking the oral microbiota to health is the nitrate (NO 3)-nitrite (NO 2)-nitric oxide (NO) pathway, which relies on oral bacteria to reduce NO 3-to NO 2. NO (generated from both NO 2-and L - arginine) regulates vascular endothelial function and therefore blood pressure (BP). By sequencing bacterial 16S rRNA genes we examined the relationships between the oral microbiome and physiological indices of NO bioavailability and possible changes in these variables following 10 days of NO 3-(12mmol/d) and placebo supplementation in young (18 – 22yrs) and old (70 – 79yrs) normotensive humans (n=18). NO 3- supplementation altered the salivary microbiome compared to placebo by increasing the relative abundance of Proteobacteria (+225%) and decreasing the relative abundance of Bacteroidetes ( − 46%; P < 0.05). After NO 3-supplementation the relative abundances of Rothia (+127%) and Neisseria (+351%) were greater, and Prevotella ( − 60%) and Veillonella ( − 65%) were lower than in the placebo condition (all P < 0.05). NO 3-supplementation increased plasma concentration of NO 2-and reduced systemic blood pressure in old (70 – 79yrs), but not young (18 – 22yrs), participants. High abundances of Rothia and Neisseria and low abundances of Prevotella and Veillonella were correlated with greater increases in plasma [NO 2] in response to NO 3-supplementation. The current ﬁ ndings indicate that the oral microbiome is malleable to change with increased dietary intake of inorganic NO 3-, and that diet-induced changes in the oral microbial community are related to indices of NO homeostasis and vascular health in vivo .
Parallel SnowModel (v1.0): a parallel implementation of a 1 Distributed Snow-Evolution Modeling System (SnowModel)

SnowModel, a spatially distributed, snow-evolution modeling system, was parallelized using Coarray Fortran for 8 high-performance computing architectures to allow high-resolution (1 m to 100’s of meters) simulations over large, regional 9 to continental scale, domains. In the parallel algorithm, the model domain is split into smaller rectangular sub-domains that 10 are distributed over multiple processor cores using one-dimensional decomposition. All of the memory allocations from the 11 original code have been reduced to the size of the local sub-domains, allowing each core to perform fewer computations and 12 requiring less memory for each process. A majority of the subroutines in SnowModel were simple to parallelize; however, 13 there were certain physical processes, including blowing snow redistribution and components within the solar radiation and 14 wind models, that required non-trivial parallelization using halo-exchange patterns. To validate the parallel algorithm and 15 assess parallel scaling characteristics, high-resolution (100 m grid) simulations were performed over several western United 16 States domains and over the contiguous United States (CONUS). The CONUS scaling experiment had approximately 71% 17 parallel efficiency; runtime decreased by a factor of 32 running on 2304 cores relative to 52 cores (the minimum number of 18 cores that could be used to run such a large domain as a result of memory and time limitations). CONUS 100 m simulations 19 were performed for 21 years (2000 – 2021) using 46,238 and 28,260 grid cells in the x and y dimensions, respectively. Each 20 year was simulated using 1800 cores and took approximately 5 hours to run.
Combination of multiplier method with qualitative interview to estimate the population size of men who have sex with men in a city of Jiangsu

Objective To estimate the population size of men who have sex with men (MSM) in a city of Jiangsu,providing data for comprehensive HIV prevention.Methods Multiplier method and qualitative interview were used in combination in the study.Spcified gay bars,bath house and websites were selected to count the number of visited MSM(r). A respondent driving sampling survey was conducted among local MSM to obtain the proportion of MSM who visited the specified organization during the given period(p). The multiplier (l/p)was calculated and the population size of MSM(N=r/p)was thus obtained.The real population size was estimated by applying the multiplier results in combination with the qualitative interview data.Results The estimated number of MSM through bars,bath house and websites were 6 618,9 797 and 26 683 respectively.The range through qualitative interview was from 20 000 to 47 000.The median of all the estimated figures listed above was 25 000,and the 25th and 75th percentiles were 20 000 and 32 000.Conclusions The population size of MSM in the city is estimated at 25 000 with a possible range from 20 000 to 32 000.The combination of multiplier method with qualitative interview may avoid factors possibly related with over high or low estimation,making the results more reliable.

We determine the modal logic of ﬁxed-point models of truth and their axiomatizations by Solomon Feferman via Solovay-style completeness re-sults. Given a ﬁxed-point model M , or an axiomatization S thereof, we ﬁnd a modal logic M such that a modal sentence ϕ is a theorem of M if and only if the sentence ϕ ∗ obtained by translating the modal operator with the truth predicate is true in M or a theorem of S under all such translations. To this end, we introduce a novel version of possible worlds semantics featuring both classical and nonclassical worlds and establish the completeness of a family of non-congruent modal logics whose internal logic is nonclassical with respect to this semantics.
