Title A multiple type bike repositioning problem

This paper investigates a new static bicycle repositioning problem in which multiple types of bikes are considered. Some types of bikes that are in short supply at a station can be substituted by other types, whereas some types of bikes can occupy the spaces of other types in the vehicle during repositioning. These activities provide two new strategies, substitution and occupancy, which are examined in this paper. The problem is formulated as a mixed-integer linear programming problem to minimize the total cost, which consists of the route travel cost, penalties due to unmet demand, and penalties associated with the substitution and occupancy strategies. A combined hybrid genetic algorithm is proposed to solve this problem. This solution algorithm consists of (i) a modified version of a hybrid genetic search with adaptive diversity control to determine routing decisions and (ii) a proposed greedy heuristic to determine the loading and unloading instructions at each visited station and the substitution and occupancy strategies. The results show that the proposed method can provide high-quality solutions with short computing times. Using small examples, this paper also reveals problem properties and repositioning strategies in bike sharing systems with multiple types of bikes. © 2016 The Authors. Published by Elsevier Ltd.

DISTURBED EATING PATTERNS AND BODY IMAGE DISTORTIONS 2 Disturbed Eating Patterns and Body Image Distortions

Women in general seem to have a complicated relationship with their bodies and their body image. A small percent of the female population develop a serious pathological eating pattern which is characterized by a disturbed image of body size and shape. This disturbance has been investigated by many researchers and the quest of finding the underlying neural correlates has progressed enormously during the last decade. The relationship between disturbed eating patterns and body image distortions is highly complicated. The purpose of this review article is to give an overview of current research literature and scientific results. The aim is to find a framework for the phenomenon of body image distortions among both healthy and non-healthy women. Differences between genders and how food intake affects body image will also be addressed. The focus lies on behavioral traits and the underlying neural correlates, with focus on both the perceptual and the cognitive-affective component.
Gaia and the Galactic Center Origin of Hypervelocity Stars

We use new Gaia measurements to explore the origin of the highest velocity stars in the hypervelocity star (HVS) survey. The measurements reveal a clear pattern in B-type stars. Halo stars dominate the sample at speeds of ≃100 km s−1 below Galactic escape velocity. Disk runaway stars have speeds up to ≃100 km s−1 above Galactic escape velocity, but most disk runaways are bound. Stars with speeds ≳100 km s−1 above Galactic escape velocity originate from the Galactic center. Two bound stars may also originate from the Galactic center. Future Gaia measurements will enable a large, clean sample of Galactic center ejections for measuring the massive black hole ejection rate of HVSs, and for constraining the mass distribution of the Milky Way dark matter halo.
Plasma levels of sex steroids (testosterone, progesterone and 17β-estradiol) in Rohu Carp Labeo rohita broodstock from Khuzestan, Iran

Sex steroids (testosterone, progesterone and 17β-estradiol) play important roles in controlling reproduction and sexual maturity in teleosts. The aim of the present study was to evaluate the seasonal changes of these steroids in Rohu Labeo rohita. Forty gravid females and males L. rohita reared in different seasons (spring, summer, autumn, winter) were caught by a net with 1 cm mesh from earthen ponds of Aquaculture Research Institute, in south of Iran. The highest levels of 17β-estradiol (122.8±17.73 ng mL-1), testosterone (0.11±0.003 ng mL-1) and progesterone (0.86±0.01 ng mL-1) in female fish were recorded in autumn. In addition, the highest concentration of testosterone in male was determined as 0.84±0.003 ng mL-1 in autumn. The mean value of dissolved oxygen in four seasons (spring, summer, autumn, and winter) were 9.21±0.77, 8.36±0.51, 10.41±0.9 and 13.14±0.72 mg L-1, with temperature 25.47±1.07, 29.88±1.42, 20.23±0.69 and 14.63±0.47◦C, respectively. Therefore, it can be inferred that progesterone was considered as the critical index for seasonal breeding selection. There was an appropriate condition in the mid winter for broodstock selection and breeding of fish with hormones manipulation.
Exploring the Effects of Different Text Stimuli on Typing Behavior

In this work we explore how different cognitive processes affected typing patterns through a computer game we call The Typing Game. By manipulating the players’ familiarity with the words in our game through their similarity to dictionary words, and by allowing some players to replay rounds, we found that typing speed improves with familiarity with words, and also with practice, but that these are independent of the number of mistakes that are made when typing. We also found that users who had the opportunity to replay rounds exhibited different typing patterns even before replaying the rounds.
Effect of Soaking and Malting Process on Chemical Compostion, Bioactive Compounds and Antioxidant Activity of some Egytian Barley Varities

Recently, the demand for functional foods containing bioactive compounds with therapeutic and disease-preventing properties has increased. This work aimed to study the effect of soaking and malting processes on nutrient and bioactive compounds in selected Egyptian barley cultivars. Three barley varieties, namely, Giza128, Giza130, and Giza 2000, were investigated. Protein content in all raw and treated samples were ranged from 8.46 to 13.30g/100g on a dry weight basis. The crude fat and carbohydrate content were slightly decreased in all treated samples. Phenolic compounds content of raw barley seeds being, 336.2, 461.8, and 460.5 mg/100g in Giza128, Giza130, and Giza 2000, respectively, while flavonoids content recorded 35.3, 58.1, and 31.3 mg/100g, respectively. Antioxidant activity in untreated samples were 29.45, 37.08, and 28.58% for Giza 128, Giza 130, and Giza 2000, respectively. Soaking of barely seed samples for 12 h increased total phenolic compounds, flavonoids, and antioxidant activity by 7.6-20.3, 11.7- 19.3, and 10.5-21%, while the germination process for 48 h increased it by 37.3-69, 30.3- 62.6, and 36-65%, respectively. With germination time (48 h), the total phenolic compounds, flavonoids, and antioxidant activity have been gradually increased and subsequently decreased with the further of malting was occurred. It can be concluded from results that their nutritional properties and therapeutic properties with potential using treated barley flour to produce functional foods have hardly improved by soaking and germinating.
Simulating the 802.11a PHY Model: How to Make It Accurate

In simulating wireless networks, modeling of the physical layer behavior is an important yet diﬃcult task. The implementation of physical layer capture, preamble detection, and carrier sense threshold plays an important role in successful frame reception in the presence of interference. We show in our testbed study that the operations of the frame reception and the capture eﬀect in real IEEE 802.11a systems diﬀer from those of popular research simulators. We present our modiﬁcations of the IEEE 802.11a PHY models to the current simulators. We implement our modiﬁcations to the QualNet simulator and show that the aggregated TCP throughput can increase up to 430% with the modiﬁed PHY model compared to the current simulation model.
Effective DDoS Mitigation in Distributed Peering Environments

© 2018 Cisco and/or it affiliates. All rights reserved. Two trends are driving the design of today’s network edge: the growth in unicast streaming video, and the continued growth of Distributed-Denial-of-Service (DDoS) attacks. The Cisco Visual Networking IndexTM has shown a 1270-percent rise in Internet traffic over the last 12 years and projects a threefold increase in the next five years. Cisco estimates that peering bandwidth, in particular, is growing at a steady 30-percent Compound Annual Growth Rate (CAGR), and some carriers are already planning for growth as high as 50 percent per year. This is mostly driven by a steady increase in unicast video streaming and other content sources versus traditional peering expansion with other network providers.
Just gaze and wave: exploring the use of gaze and gestures for shoulder-surfing resilient authentication

Eye-gaze and mid-air gestures are promising for resisting various types of side-channel attacks during authentication. However, to date, a comparison of the different authentication modalities is missing. We investigate multiple authentication mechanisms that leverage gestures, eye gaze, and a multimodal combination of them and study their resilience to shoulder surfing. To this end, we report on our implementation of three schemes and results from usability and security evaluations where we also experimented with fixed and randomized layouts. We found that the gaze-based approach outperforms the other schemes in terms of input time, error rate, perceived workload, and resistance to observation attacks, and that randomizing the layout does not improve observation resistance enough to warrant the reduced usability. Our work further underlines the significance of replicating previous eye tracking studies using today's sensors as we show significant improvement over similar previously introduced gaze-based authentication systems.
Classes of Multiplication Operators and Their Limit Operators

Limit operators have proven to be a device for the study of several properties of an operator including Fredholmness and invertibility at infinity, but also the applicability of approximation methods. For band-dominated operators, the question of existence and structure of their limit operators essentially reduces to the study of multiplication operators and their limit operators, which is the topic of this paper.
1 6 M ar 2 01 5 Cumulative Conditional Expectation Index

In this paper we study the cumulative conditional expectation function (CCEF) in the copula context. It is shown how to compute CCEF in terms of the cumulative copula function, this natural representation allows to deduce some useful properties, for instance with applications to convex combination of copulas. We introduce approximations of CCEF based on Bernstein polynomial copulas. We introduce estimators for CCEF, which were constructed through Bernstein polynomial estimators for copulas. The estimators are asymptotically normal and biased for CCEF.
Biophysics of Chromatin Remodeling.

As primary carriers of epigenetic information and gatekeepers of genomic DNA, nucleosomes are essential for proper growth and development of all eukaryotic cells. Although they are intrinsically dynamic, nucleosomes are actively reorganized by ATP-dependent chromatin remodelers. Chromatin remodelers contain helicase-like ATPase motor domains that can translocate along DNA, and a long-standing question in the field is how this activity is used to reposition or slide nucleosomes. In addition to ratcheting along DNA like their helicase ancestors, remodeler ATPases appear to dictate specific alternating geometries of the DNA duplex, providing an unexpected means for moving DNA past the histone core. Emerging evidence supports twist-based mechanisms for ATP-driven repositioning of nucleosomes along DNA. In this review, we discuss core experimental findings and ideas that have shaped the view of how nucleosome sliding may be achieved. Expected final online publication date for the Annual Review of Biophysics, Volume 50 is May 2021. Please see http://www.annualreviews. org/page/journal/pubdates for revised estimates.
Prognostic value of cardiac 123I‐metaiodobenzylguanidine imaging for predicting cardiac events after transcatheter aortic valve replacement

In patients with aortic valve stenosis (AS), cardiac sympathetic nervous (CSN) dysfunction and its improvement after transcatheter aortic valve replacement (TAVR) have been reported. The prognostic impact of CSN function remains unclear. This study investigated the prognostic value of cardiac 123I‐metaiodobenzylguanidine (MIBG) imaging for predicting cardiac events after TAVR.
Predictive Ability of Direct Electrical Stimulation on Facial Nerve Function Following Vestibular Schwannoma Surgery: A Systematic Review and Meta-analysis.

OBJECTIVE Facial nerve preservation is critical in vestibular schwannoma (VS) surgery. Direct electrical stimulation (DES) is a widely used method for intraoperative localization of the facial nerve and assessment of nerve integrity. We sought to assess the predictive ability of DES parameters on facial nerve function post-VS surgery. DATABASES REVIEWED A systematic literature search of English-language studies published from 1946 to 2019 was undertaken using EMBASE, MedLine/PubMed, and the Cochrane Central Register of Controlled Trials. METHODS Included studies involved patients undergoing VS surgery and assessed predictive ability of any DES parameter on postoperative facial function. Two authors independently reviewed studies and extracted data. Meta-analysis of diagnostic accuracy of DES parameters was used to calculate pooled sensitivities and specificities of common cutoffs. For DES parameters reported by less than four studies, outcomes were reported descriptively. RESULTS A MST cutoff of 0.10 mA had sensitivity of 0.76 (95% CI 0.53-0.90) and specificity 0.68 (95% CI 0.42-0.87) for facial function in the long term, and MST 0.05 mA had sensitivity 0.73 (95% CI 0.58-0.84) and specificity 0.74 (95% CI 0.59-0.85). CMAP amplitude < 500 μV had sensitivity of 0.87 (95% CI 0.78-0.93) for poor short-term facial function. CONCLUSIONS A CMAP amplitude response < 500 μV is sensitive for poor short-term facial function, whereas MST values of 0.05 mA and 0.10 mA are both sensitive and specific in the long term. Other DES parameters may be able to accurately predict both short- and long-term postoperative facial function, but have been less studied.
Comparison of the Effect of Cold Dialysate versus Stretching Exercises on Severity of Restless Legs Syndrome in Patients Undergoing Hemodialysis: A Randomized Controlled Trial

Background: Restless legs syndrome (RLS) is prevalent among patients undergoing hemodialysis. This research suggests that cold dialysis solution and stretching exercises are effective approaches reducing RLS; however, they should be adopted according to the patient’s condition. Aim: This study aimed to compare cold dialysate with stretching exercises on RLS severity in patients undergoing hemodialysis. Method: This two-group randomized clinical trial was conducted on 44 hemodialysis patients with RLS. One group received cold dialysis (35.5°C) and the other group performed stretching exercises in two hemodialysis centers in Sabzevar, Razavi Khorasan Province, Iran, in 2019. The severity of RLS was measured in both groups using the IRLS scale at the baseline and end of each week for 6 weeks. The data were analyzed in SPSS (version 21) using repeated measures ANOVA and Friedman’s test. Results: The mean age of participants in cold dialysis and stretching exercise groups were 54.5±13.6 and 54.5±10.8 years, respectively. The Friedman test results showed a significant reduction in the severity of RLS in both groups (P=0.001). Moreover, the repeated measures ANOVA results revealed that the time effect was significant (P=0.001). However, group effect (P=0.09) and interaction between time and group (P=0.25) were not significantly different. Implications for Practice: Both methods of cold dialysate and stretching exercises decreased RLS severity; therefore, they can be suggested to nurses as effective strategies. Due to the limited sample size, studies with larger sample sizes are recommended.
Passively Q-switched microchip laser at 1.5 µm

We demonstrate a compact laser source in the eye-safe wavelength regime (≈1.5 µm) that produces peak powers up to 10.6 kW at pulse durations of 0.84 ns with a repetition rate exceeding 1 kHz. An Er:Yb:glass microchip laser was passively Q-switched with a semiconductor saturable absorber mirror (SESAM). We investigated SESAM damage under Q-switching conditions and developed an improved SESAM design that can withstand microjoule pulses.
Role of Host-Mediated Post-Translational Modifications (PTMs) in RNA Virus Pathogenesis

Being opportunistic intracellular pathogens, viruses are dependent on the host for their replication. They hijack host cellular machinery for their replication and survival by targeting crucial cellular physiological pathways, including transcription, translation, immune pathways, and apoptosis. Immediately after translation, the host and viral proteins undergo a process called post-translational modification (PTM). PTMs of proteins involves the attachment of small proteins, carbohydrates/lipids, or chemical groups to the proteins and are crucial for the proteins’ functioning. During viral infection, host proteins utilize PTMs to control the virus replication, using strategies like activating immune response pathways, inhibiting viral protein synthesis, and ultimately eliminating the virus from the host. PTM of viral proteins increases solubility, enhances antigenicity and virulence properties. However, RNA viruses are devoid of enzymes capable of introducing PTMs to their proteins. Hence, they utilize the host PTM machinery to promote their survival. Proteins from viruses belonging to the family: Togaviridae, Flaviviridae, Retroviridae, and Coronaviridae such as chikungunya, dengue, zika, HIV, and coronavirus are a few that are well-known to be modified. This review discusses various host and virus-mediated PTMs that play a role in the outcome during the infection.
Perceptions of love across the lifespan

This study investigated perceptions of love across the lifespan using Sternberg’s triangular theory of love, which distinguishes between passion, intimacy, and commitment. The study aimed to (a) investigate the psychometric properties of the short Triangular Love Scale (TLS-short) in adolescents and adults (see Appendix), and (b) track age and gender differences in the three love components of the TLS-short in a sample of 12- to 88-year-olds (N = 2791). The three-factor structure of the TLS-short was confirmed in both the adolescent and adult sample. Adolescents (12–17 years) reported lower levels of all love components compared to young adults (18–30 years). Late adults (50+) reported lower levels of passion and intimacy, but similar levels of commitment compared to young (18–30 years) and middle adults (30–50 years). Gender differences in the perceptions of all three love components were present but less sizeable than suggested in popular accounts and earlier academic research.
Mortgage Market and Regional Development in Greece: Peculiarities and Consequences

This paper examines regional inequalities through the lens of the residential mortgage market in Greece, as an example of the South of Europe in the 2000s. It is commonly accepted that in recent years the financial deepening of economies has become one major dynamic that characterizes advanced economies, with the mortgage market constituting a great part of it (Sassen, 2009). This growing trend towards the financial system does not function in a space-neutral, homogeneous way, but one could detect spatial and social differentiations and inequalities across regions and multiple scales. In that context, certain regions have limited access to financial resources, while cities play a central role for real estate and mortgage market, with high property prices, and have become a major vehicle for the production of uneven development far beyond the local/city scale (Golubchikov, 2013). In a framework in which cities “may be conceived as places designed to maximize the interests of a small, powerful elite” (Aalbers, 2013), the “urbanisation” of the residential mortgage market will be discussed.
Nonlinear q-Stokes phenomena for q-Painlevé I

We consider the asymptotic behavior of solutions of the first -difference Painlevé equation in the limits and . Using asymptotic power series, we describe four families of solutions that contain free parameters hidden beyond-all-orders. These asymptotic solutions exhibit Stokes phenomena, which is typically invisible to classical power series methods. In order to investigate such phenomena we apply exponential asymptotic techniques to obtain mathematical descriptions of the rapid switching behavior associated with Stokes curves. Through this analysis, we also determine the regions of the complex plane in which the asymptotic behavior is described by a power series expression, and find that the Stokes curves are described by curves known as -spirals.
1 Bi-Demographic Changes and Current Account using SVAR Modeling : Evidence from Saudi Arabia

The paper aims to explore the impacts of bi-demographic structure on the current account and growth. Using a SVAR modeling, we track the dynamic impacts between these underlying variables. New insights have been developed about the dynamic interrelation between population growth, current account and economic growth. The long-run net impact on economic growth of the domestic working population growth and demand labor for emigrants is positive, due to the predominant contribution of skilled emigrant workers. Besides, the positive long-run contribution of emigrant workers to the current account growth largely compensates the negative contribution from the native population, because of the predominance of skilled compared to unskilled workforce. We find that a positive shock in demand labor for emigrant workers leads to an increasing effect on native active age ratio. Thus, the emigrants appear to be more complements than substitutes for native workers.
Using graphene oxide as a sacrificial support of polyoxotitanium clusters to replicate its two-dimensionality on pure titania photocatalysts

The nanostructure optimisation of metal oxides is of crucial importance to exploit their qualities in artificial photosynthesis, photovoltaics and heterogeneous catalysis. Therefore, it is necessary to find viable and simple fabrication methods to tune their nanostructure. Here we reveal that graphene oxide flakes, known for their nano- and two-dimensionality, can be used as a sacrificial support to replicate their nano- and two-dimensionality in photocatalytic titania. This is demonstrated in the calcination of Ti16O16(OEt)32 polyoxotitanium clusters together with graphene oxide flakes, which results in pure titania nanoflakes of <10 nm titania nanoparticles in a two-dimensional arrangement. These titania nanoflakes outperform the titania prepared from only Ti16O16(OEt)32 clusters by a factor of forty in the photocatalytic hydrogen production from aqueous methanol suspensions, as well as the benchmark P25 titania by a factor of five. These outcomes reveal the advantage of using polyoxotitanium clusters with graphene oxide and open a new avenue for the exploitation of the vast variety of polyoxometalate clusters as precursors in catalysis and photovoltaics, as well as the use of graphene oxide as a sacrificial support for nanostructure optimisation.
