Zjawisko momentum a efekty kalendarzowe

Liczne prace empiryczne (m.in. [5], [7], [10], [11], [12]) sugerują wystepowanie na rynkach akcji tzw. efektu momentum, czyli zjawiska polegającego na średniookresowej tendencji do kontynuacji wzrostow lub spadkow cen akcji. Oznacza to, ze notowania spolek, ktorych ceny akcji wzrosly w niedalekiej przeszlości (w ciągu minionych kilku miesiecy) wykazują dalsze wzrosty w ciągu kilku kolejnych miesiecy. Analogicznie, akcje, ktorych ceny spadaly w ostatnich miesiącach wykazują tendencje do dalszych spadkow. W zalezności od badanego rynku efekt ten trwal od kilku do kilkunastu miesiecy. Po tym czasie najcześciej nastepowalo odwrocenie tendencji, tzn. akcje, ktorych ceny wcześniej rosly zaczynaly tracic na wartości ([3], [4], [8]). Nalezy zaznaczyc, ze upowszechnienie wiedzy o zjawisku momentum nie przyczynilo sie do jego zaniku [6]. Przyczyn tego zjawiska upatruje sie w nieadekwatnej, zbyt silnej lub zbyt slabej, reakcji inwestorow na naplywające na rynek informacje. Wystepowanie efektu momentum stalo sie podstawą do konstrukcji strategii inwestycyjnych polegających na kupowaniu akcji charakteryzujących sie najwiekszymi wzrostami w trakcie ostatnich kilku miesiecy i krotkiej sprzedazy akcji wykazujących w tym okresie najwieksze spadki. Ograniczeniem stosowalności tychze strategii staly sie jednak wysokie koszty transakcyjne związane glownie z krotką sprzedazą. Wystepowanie efektu momentum na Gieldzie Papierow Wartościowych w Warszawie zostalo potwierdzone przez Szyszke [11] i Wojtowicza [12]. Badania te, podobnie jak wcześniejsze dotyczące skuteczności strategii momentum (np. [5]), prowadzone byly na podstawie danych miesiecznych lub kwartalnych, tzn. klasyfikacja spolek do odpowiednich portfeli dokonywana byla na początku lub
The Impact of Oxidative Stress and AKT Pathway on Cancer Cell Functions and Its Application to Natural Products

Oxidative stress and AKT serine-threonine kinase (AKT) are responsible for regulating several cell functions of cancer cells. Several natural products modulate both oxidative stress and AKT for anticancer effects. However, the impact of natural product-modulating oxidative stress and AKT on cell functions lacks systemic understanding. Notably, the contribution of regulating cell functions by AKT downstream effectors is not yet well integrated. This review explores the role of oxidative stress and AKT pathway (AKT/AKT effectors) on ten cell functions, including apoptosis, autophagy, endoplasmic reticulum stress, mitochondrial morphogenesis, ferroptosis, necroptosis, DNA damage response, senescence, migration, and cell-cycle progression. The impact of oxidative stress and AKT are connected to these cell functions through cell function mediators. Moreover, the AKT effectors related to cell functions are integrated. Based on this rationale, natural products with the modulating abilities for oxidative stress and AKT pathway exhibit the potential to regulate these cell functions, but some were rarely reported, particularly for AKT effectors. This review sheds light on understanding the roles of oxidative stress and AKT pathway in regulating cell functions, providing future directions for natural products in cancer treatment.
Urban Residents’ Willingness to Choose and Pay for ADAS and Autonomous Driving Functions: Comparison of Two Cities in China

ADAS and autonomous driving are booming. As technologies continue to innovate and mature, whether travelers understand, accept, and buy them will directly impact the technological development, popularization, and profitability of these products. This study analyzes the influence of urban residents’ personal, family, and commuting characteristics on their willingness to choose and pay for ADAS and autonomous driving functions. Using the questionnaire survey data for Jiading and Meishan in China, Logit models are established for willingness to choose, and linear regression models are established for willingness to pay. Although Jiading and Meishan are similar in terms of city size and population, there are some differences in the influencing factors for willingness to choose and pay because of the differences in industrial structure, city culture, and residents’ commuting habits. The results show that significant influencing factors vary for different levels of ADAS and autonomous driving functions. The findings of this research can provide a reference for city authorities, designers, and sellers of ADAS products or autonomous vehicles to identify potential buyers and promote related products.
Using different method for detection Helicobacter pylori that causing gastric cancer and compared with invasive method in the Al-Ramadi city

The study aims at finding out the most efficient method in the diagnosis and the easiest sample in usage. The study collects 50 samples from outpatients who customarily visit the medical sight unit. The collections of the samples include biopsy tissue, blood, saliva and stool from each patient, as well as 30 samples were collected from the control group (people who are not infected). The samples of biopsy tissue are used to test (Culture, rapid urease enzyme, and histopathology) through using saliva sample of the culture test. It also uses stool samples, rapid antigen stool test (strip). However, the serum samples were used to detect antibodies formed IgG against infection with the Helicobacter pylori . The study compared between the invasive and non- invasive. the culture test was 6% of sensitivity and 100% of specificity, the rapid urease enzyme test was 66% of sensitivity and 90% of specificity and the histopathologic test was 14% of sensitivity and 100% of specificity. The rapid stool antigen test was 54% of sensitivity and 80% of specificity then the serum ELISA test with a sensitivity of 58% and specificity of 60% . It was found after comparing invasive with non-invasive methods that the rapid urease enzyme in invasive methods is the most efficient in diagnosis , also The non-invasive methods found the rapid stool antigen test the most efficient in diagnosis.
Quantitative tools in urban morphology: combining space syntax, spacematrix and mixed-use index in a GIS framework

A spatial modelling method is presented that utilizes a Geographical Information System (GIS) to combine the analyses of three constituent elements of urban form recognized by M. R. G. Conzen. The aim is to produce a spatial classification system for various types of urban areas, and reveal how they perform socio-economically. In the proposed method, space syntax, spacematrix, and mixed-use index (MXI) are used to assess street-network integration, building density, and land-use mixture. These elements are incorporated into a single framework. The validity of the method is initially tested through human behaviour records based on Global Positioning System (GPS) tracking. The method is then used in a comparison of the various spatial parameters of three new towns and one old town in the Netherlands. The results show that the old town has higher values of streetnetwork integration, building density, and land-use mixture than the new towns. The method functions well as a diagnostic tool for suggesting ways of improving socio-economic performance in urban areas. For example a spatial diagnosis can be made for new towns suffering from a lack of vibrant street life. The method helps to reveal the interdependences of street-network integration, building density, and land-use mixture in urban transformation processes.

Finite-time control strategy for swarm planar underactuated robots via motion planning and intelligent algorithm

The swarm planar underactuated robots have the ability to organize each robot to complete task in a finite time and the characteristics of ignoring gravity, energy saving, light weight, and so on. In this paper, we propose control strategy for such robot via motion planning and intelligent algorithm. First, we establish a unified dynamic model and analysis its underactuated characteristics. In order to enable all links to reach the target position smoothly in a finite time, a suitable trajectory is planned and parameters are optimized by the differential evolution algorithm (DEA). Then, the controllers are designed for each planar underactuated robot. Finally, the simulation results show that the proposed strategy is effective.
Temperature-Dependent Electrical Characteristics of p-Channel Mode Feedback Field-Effect Transistors

In this study, the temperature-dependent electrical characteristics of p-channel mode feedback field-effect transistors (FBFETs) were examined at temperatures ranging from 250 to 425 K. Their steep subthreshold swings of less than 1 mV/dec were maintained even at temperatures up to 400 K. As the temperature increased to 400 K, the latch-up voltage shifted from −0.951 to −0.613 V, which was caused by a reduction in the potential barriers in the channels of the FBFETs. High $I_{\mathrm {on}}/I_{\mathrm {off}}$ ratios above 108 were maintained in the temperature range of 250 to 400 K. However, at temperatures over 400 K, the FBFETs were turned on regardless of the gate voltages owing to the generation of a thermally induced positive feedback loop.
Biomonitoring
the status of aquatic bodies using zooplankton as surrogate species amidst
urban landscape

The concept of surrogates in biodiversity assessments has been widely accepted in the recent years. Surrogates are taxonomic groups that indicate the overall biodiversity at a particular site. Zooplankton is an important component of the aquatic ecosystem, playing a major role in energy transfer between the phytoplankton or producers and the consumers at higher trophic levels. In this study zooplanktons were considered as surrogates for biomonitoring status of two aquatic bodies amidst urban landscape at the southern fringes of Kolkata, West Bengal, India through different seasons. Zooplankton diversity and abundance was found to vary with seasons in both the ponds in correlation with limnological parameters. Pond 1 was found to be larger in size, having partial macrophyte cover in comparison with Pond 2 which is smaller and devoid of any macrophyte cover over the study period. The Pond 1 elucidated higher diversity of zooplankton having higher water pH and phosphate concentration and less nitrite concentration. Pond 2 elaborated less zooplankton diversity with lower pH, less phosphate and higher nitrite concentration. Diversity and abundance of zooplankton surrogates provided valuable information about the status of water bodies amidst urban landscape and can be utilised as a tool for biomonitoring.
The Wilson-Bappu Effect - 50 Years Later

Wilson and Bappu (1957) published an empirical correlation between the FHWM of the emission core of the CaII K-Line at 3933A and the intrinsic luminosity among late-type dwarf, giant, and supergiant stars. Later on, Stencel (1977) extended this luminosity calibrator by using so-called wing emission lines in the wings of the H and K lines. Efforts to extend these techniques to the brightest supergiants in local group galaxies were frustrated by the limits of photographic coude’ spectra even on 4-meter telescopes at the time. With the advent of CCD spectra and S/N possible with 8-meter telescopes, we re-examine the potential for extragalactic hypergiant star distance calibration. Wilson and Bappu (1957) published an empirical correlation between the Full width at Half Maximum (FWHM) of the emission core of the Ca+ Fraunhofer K line at 3933Å, and the intrinsic luminosity among late type dwarf, giant and supergiant stars. Later on, Stencel (1977) extended this luminosity calibrator by using so called wing emission lines in the extended absorption wings of the Ca+ K and H lines, the latter centered at 3968Å. Efforts at that time to extend these techniques to the brightest supergiants in local group galaxies were frustrated by the limited sensitivity of photographic coude’ spectra even on 4-meter telescopes. With the advent of CCD spectra and S/N possible with 8-meter telescopes, we discuss here the potential for calibrating extragalactic supergiant and hypergiant star distances. Distance determination has long been a central problem in astronomy. The advent of HIPPARCOS has enhanced knowledge of trigonometric parallax values for a large number of stars around the sun (ESA, 1997). However, even that tenfold improvement over photographic-era parallaxes does not encompass many high luminosity stars crucial for accurate distances to stellar associations in our galaxy and others. Among the applications of the enhanced Wilson-Bappu effect are distance determinations for the absolutely highest luminosity stars in the Milky Way and other galaxies, as well as distance constraints on AGB stars, where in both extremes, circumstellar absorption obliterates any meaningful measure of the core emission width of the Ca+ K line itself. The residual wing emission lines (Stencel 1977), vary in proportion and are much less subject to the overlying opacity of the stellar atmosphere shining through in the most luminous stars known.
Adsorption of Rhodamine 6G Dye onto Al-MCM-41 and MCM-41 Mesoporous Materials

The present study aimed to evaluate the potential of mesoporous silica MCM-41 and Al-MCM-41 (molar ratio Si/Al = 20) for the removal of Rhodamine 6G (Rh6G) from aqueous solution. The adsorbents were characterised by XRD, FTIR, SEM-EDX, BET, and UV-Raman. Obtained results related to XRD analysis indicated that the MCM-41 structure remained intact after the incorporation of Al species. Kinetic adsorption study showed that the higher removal (88.75 %, 26.62 mg g −1 ) of Rh6G dye was achieved by Al-MCM-41 at 60 min. FTIR analysis showed that hydrogen bonding played the dominant role in the Rh6G removal mechanism, while the pH results showed that electrostatic interaction was also a key factor. This study shows that the prepared mesoporous materials are inexpensive and efficient adsorbents for the removal of cationic dyes.
How sociotechnical imaginaries shape consumers’ experiences of and responses to commercial data collection practices

ABSTRACT How is the ongoing “datafication” in society experienced by consumers? Critical discussions regarding the impact of datafication on consumers seldom study consumers’ actual experiences. Conversely, the studies that do exist of consumers and their experiences of datafication tend to take an individualistic approach, arguing that how consumers experience and respond to the ongoing datafication is the result of their individual psychological make-up or the result of processes of cost–benefit calculations. Against that background, this article will instead show that the ways in which consumers experience and respond to datafication is linked to a number of broader sociotechnical imaginaries. Based on in-depth user interviews and drawing on previous work on sociotechnical imaginaries, this article develops an analysis of consumers’ multiple imaginaries of data collection practices. Findings show that how consumers approach data collection operations is shaped by sociotechnical imaginaries that were both individually and collectively performed by consumers interacting with and using data-collecting devices.
Age-Dependent Heterogeneity of Lymph Node Metastases and Survival Identified by Analysis of a National Breast Cancer Registry

Background: For several cancers, including those of the breast, young age at diagnosis is associated with an adverse prognosis. Although this effect is often attributed to heritable mutations such as BRCA1/2, the relationship between pathologic features, young age of onset, and prognosis for breast cancer remains unclear. In the present study, we highlight links between age of onset and lymph node metastasis (NM) in US women with breast cancer. Methods: Case listings from Surveillance, Epidemiology, and End Result (SEER) 18 registry data for women with breast cancer, which include information on race, were used. NM and its associated outcomes were evaluated for a subset of women with receptor subtype information and then compared against a larger, pre-subtype validation set of data from the same registry. Age of diagnosis was a 5-category variable; under 40 years, 40–49 years, 50–59 years, 60–69 years and 70+ years. Univariate and adjusted multivariate survival models were applied to both sets of data. Results: As determined with adjusted logistic regression models, women under 40 years old at diagnosis had 1.55 times the odds of NM as women 60–69 years of age. The odds of NM for (HR = hormone receptor) HR+/HER2+, HR-/HER2+, and triple-negative breast cancer subtypes were significantly lower than those for HR+/HER2-. In subtype-stratified adjusted models, age of diagnosis had a consistent trend of decreasing odds of NM by age category, most noticeable for HR+ subtypes of luminal A and B. Univariate 5-year survival by age was worst for women under 40 years, with NM attributable for 49% of the hazard of death from cancer in adjusted multivariate models. Conclusions: Lymph node metastasis is age-dependent, yet not all molecular subtypes are clearly affected by this relationship. For <40-yr-old women, NM is a major cause for shorter survival. When stratified by subtype, the strongest associations were in HR+ groups, suggesting a possible hormonal connection between young age of breast cancer onset and NM.
The Relationship between Physical Activity during Pregnancy, Post-CesareanSection Pain, and Analgesia Requirement

Background & Objective: The cesarean section increases worldwide and has many side effects, including acute pain. This study investigated the relationship between physical activity during pregnancy, analgesic consumption, and maximal postoperative pain in women with low segment cesarean section. Materials & Methods: 340 Cesarean section women were interviewed by demographic and global physical activity questionnaires during the pre-operative visits. The participants were categorized into high, moderate, and low physical activity groups (high PA, moderate PA, low PA, respectively) according to the global physical activity questionnaire guidelines. The maximal postoperative pain (MPP), the type, and doses of analgesia used/2 days were recorded. Pearson correlation, Chi-square, and one-way ANOVA were used to analyze the data. Results: MPP was reduced in the high PA group (5.48 ±1.72) compared to the moderate (6.46±1.30) and low PA groups (6.97±1.92; p<0.0005, p<0.0005, respectively). There was a difference between the moderate and low PA groups (p=0.04). Paracetamol was the common analgesic without significant difference among groups (p=0.37). The numbers of paracetamol doses significantly reduced in the high PA group (3.31±1.65) compared to the low PA group (4.03±2.01, p=0.01). MPP had a significant and low negative correlation with total physical activity (r=-0.25, p=0.0005). There was a negative significant correlation between occupation (r=-0.491, p=0.0005), recreational (r=-0.262, p=0.0005), and travel activities (r=--0.150, p=0.006) with MPP. There was a low positive correlation between sedentary activity and MPP (r=0.23, p=0.0005). Conclusions: Maternal physical activity can be a non-pharmacological and cost-effective method of pain management.
Increased Vitamin A Level is associated with Clinical Improvement in Mild Acne Vulgaris: A Pre-test and Post-test Clinical Trial

AV is a global cutaneous disorder that although is benign, can significantly affect the patient’s quality of life. The pathognomonic feature of the disease is the emergence of comedones. There are four known pathophysiology of AV, increased sebum production, ductal cornification, colonization of the bacteria P. acnesin the pilosebaceous unit, and inflammation. Furthermore, Vitamin A although already a well-established acne treatment that can affect all four of these factors, here are still limited data regarding the quantitative measurement of vitamin A itself in acne vulgaris cases. This study seeks to review the association between vitamin A levels measured quantitatively using ELISA with the outcome of inflamed lesions and comedones prior and after treatment with Tretinoin 0.025% in patients with mild AV. Our studies found that increased level of vitamin A is associated with significant clinical improvements in both inflamed and non-inflamed AV lesions.
Dynamics of Particles in Non Scaling FFAG Accelerators

STFC Daresbury Laboratory, Daresbury, Warrington, Cheshire, WA4 4AD, United Kingdom(Dated: April 14, 2009)Non scaling Fixed-Field Alternating Gradient (FFAG) accelerators have an unprecedented po-tential for muon acceleration, as well as for medical purposes based on carbon and proton hadrontherapy. They also represent a possible active element for an Accelerator Driven Subcritical Reactor(ADSR). Starting from ﬁrst principle the Hamiltonian formalism for the description of the dynamicsof particles in non scaling FFAG machines has been developed. The stationary reference (closed)orbit has been found within the Hamiltonian framework. The dependence of the path length on theenergy deviation has been described in terms of higher order dispersion functions. The latter havebeen used subsequently to specify the longitudinal part of the Hamiltonian. It has been shown thathigher order phase slip coeﬃcients should be taken into account to adequately describe the acceler-ation in non scaling FFAG accelerators. A complete theory of the fast (serpentine) acceleration innon scaling FFAGs has been developed. An example of the theory is presented for the parametersof the Electron Machine with Many Applications (EMMA), a prototype electron non scaling FFAGto be hosted at Daresbury Laboratory.
Advances in Computational Dynamics of Particles, Materials and Structures

Computational methods for the modeling and simulation of the dynamic response and behavior of particles, materials and structural systems have had a profound influence on science, engineering and technology. Complex science and engineering applications dealing with complicated structural geometries and materials that would be very difficult to treat using analytical methods have been successfully simulated using computational tools. With the incorporation of quantum, molecular and biological mechanics into new models, these methods are poised to play an even bigger role in the future. Advances in Computational Dynamics of Particles, Materials and Structures not only presents emerging trends and cutting edge state-of-the-art tools in a contemporary setting, but also provides a unique blend of classical and new and innovative theoretical and computational aspects covering both particle dynamics, and flexible continuum structural dynamics applications. It provides a unified viewpoint and encompasses the classical Newtonian, Lagrangian, and Hamiltonian mechanics frameworks as well as new and alternative contemporary approaches and their equivalences in [start italics]vector and scalar formalisms[end italics] to address the various problems in engineering sciences and physics.
