description: We have investigated the properties of a model of 1D anyons interacting through a $δ$-function repulsive potential. The structure of the quasi-periodic boundary conditions for the anyonic field operators and the many-anyon wavefunctions is clarified. The spectrum of the low-lying excitations including the particle-hole excitations is calculated for periodic and twisted boundary conditions. Using the ideas of the conformal field theory we obtain the large-distance asymptotics of the density and field correlation function at the critical temperature T=0 and at small finite temperatures. Our expression for the field correlation function extends the results in the literature obtained for harmonic quantum anyonic fluids.

description: It has been argued by Zurek and Kibble that the likelihood of producing defects in a continuous phase transition depends in a characteristic way on the quench rate. In this paper we discuss an improved experiment for measuring the Zurek-Kibble scaling exponent $σ$ for the production of fluxons in annular symmetric Josephson Tunnel Junctions. We find $σ\simeq 0.5$. Further, we report accurate measurements of the junction gap voltage temperature dependence which allow for precise monitoring of the fast temperature variations during the quench.

description: In previous work the authors introduced a notion of generic states and obtained criteria for local equivalence of them. Here they introduce the concept of CHG states maintaining the criteria of local equivalence. This fact allows the authors to halve the number of invariants necessary to characterize the equivalence classes under local unitary transformations for the set of tripartite states whose partial trace with respect to one of the subsystems belongs to the class of CHG mixed states.

Cancer

description: Gastric cancer is a foremost one among many regular carcinoma cases globally and most of the enhanced treatments could not significantly decrease the mortality range of this cancer. The current work is planned to develop a new rote for the synthesis of a nanophotocatalyst and substituted chromenones that are effective drugs against gastric cancer. Thus, CuO as a new heterogeneous green nanophotocatalyst is biosynthesized from Cressa leaf extract and the prepared nanophotocatalyst is applied in the synthesis of chromenones under air by the mediation of a green color LED in a solventless condition. In addition, in order to obtain the optimum synthesis conditions for the photocatalytic process, a Central Composite Design (CCD) is also applied, which predicted the optimal temperature of 33.8 °C, reaction time of 69 min, and catalyst amount of 5.9 mg. Fortunately, these findings fitted well with the experimentally attained optimal conditions. Furthermore, reusability and stability tests guarantee acceptable reproducibility of the protocol. It is found that the photocatalytic reaction mainly occurs through a radical-based mechanism involving •O2-, OH•, and h+. The significant features of this study invole the photocatalytic nature of the protocol with the irradiation of a commercially cheap LED, simple and inexpensive photocatalyst, low temperature, high yield, solvent-free, facile work-up, wide scope, and proper atom economy. At the final part of this report, the in-vitro cellular cytotoxicity of CuO nanoparticles and 3-nitro-substituted chromene is examined on KATO-III human gastric cell line with MTT assay. The reduction in cell viability confirmed cytotoxicity of these materials against the performed cancer cell line.
Damped harmonic oscillator interpretation of the soft-state power spectra of Cyg X-1

description: We develop a model of an accretion disc in which the variability induced at a given radius is governed by a damped harmonic oscillator at the corresponding epicyclic frequency. That variability induces both linear and non-linear responses in the locally emitted radiation. The total observed variability of a source is the sum of these contributions over the disc radius weighted by the energy dissipation rate at each radius. It is shown that this simple model, which effectively has only three parameters including the normalization, can explain the range of the power spectra observed from Cyg X-1 in the soft state. Although a degeneracy between the black hole mass and the strength of the damping does not allow a unique determination of the mass, we can still constrain it to <16--20 solar masses. We also show that our model preserves the observed linear rms-flux relationship even in the presence of the non-linear flux response.

description: In a high dispersion 1 micron survey of 39 classical T Tauri stars veiling is detected in 80%, and He I 10830 and Pgamma line emission in 97% of the stars. On average, the 1 micron veiling exceeds the level expected from previously identified sources of excess emission, suggesting the presence of an additional contributor to accretion luminosity in the star-disk interface region. Strengths of both lines correlate with veiling, and at Pgamma there is a systematic progression in profile morphology with veiling. He I 10830 has an unprecedented sensitivity to inner winds, showing blueshifted absorption below the continuum in 71% of the CTTS compared to 0% at pgamma. This line is also sensitive to magnetospheric accretion flows, with redshifted absorption below the continuum found in 47% of the CTTS compared to 24% at Pgamma. The blueshifted absorption at 10830 shows considerable diversity in its breadth and penetration depth into the continuum, indicating that a range of inner wind conditions exist in accreting stars. We interpret the broadest and deepest blue absorptions as formed from scattering of the 1 micron continuum by outflowing gas whose full acceleration region envelopes the star, suggesting radial outflow from the star. In contrast, narrow blue absorption with a range of radial velocities more likely arises via scattering of the 1 micron continuum by a wind emerging from the inner disk. Both stellar and disk winds are accretion powered since neither is seen in non-accreting WTTS and among the CTTS helium strength correlates with veiling.

The Stochastic Heat Equation with a Fractional-Colored Noise: Existence of the Solution
Creators: name: Balan, Raluca

Subjects: subject: Probability (math.PR)

description: In this article we consider the stochastic heat equation $u_{t}-Δu=\dot B$ in $(0,T) \times \bR^d$, with vanishing initial conditions, driven by a Gaussian noise $\dot B$ which is fractional in time, with Hurst index $H \in (1/2,1)$, and colored in space, with spatial covariance given by a function $f$. Our main result gives the necessary and sufficient condition on $H$ for the existence of the process solution. When $f$ is the Riesz kernel of order $α\in (0,d)$ this condition is $H>(d-α)/4$, which is a relaxation of the condition $H>d/4$ encountered when the noise $\dot B$ is white in space. When $f$ is the Bessel kernel or the heat kernel, the condition remains $H>d/4$.

description: A combined BCDE (Brans-Dicke and Einstein-Cartan) theory with lambda-term is developed through Raychaudhuri's equation, for inflationary scenario. It involves a variable cosmological constant, which decreases with time, jointly with energy density, cosmic pressure, shear, vorticity, and Hubble's parameter, while the scale factor, total spin and scalar field increase exponentially. The post-inflationary fluid resembles a perfect one, though total spin grows, but the angular speed does not (Berman, 2007d).

description: Clinical trials for HIV prevention can require knowledge of infection times to subsequently determine protective drug levels. Yet, infection timing is difficult when study visits are sparse. Using population nonlinear mixed-effects (pNLME) statistical inference and viral loads from 46 RV217 participants, we developed a relatively simple HIV primary infection model that achieved excellent fit to all data. We also discovered APTIMA assay values from the study strongly correlated with viral loads, enabling imputation of very early viral loads for 28/46 participants. Estimated times between infecting exposures and first positives were generally longer than prior estimates (average of two weeks) and were robust to missing viral upslope data. On simulated data, we found tighter sampling before diagnosis improved estimation more than tighter sampling after diagnosis. Sampling weekly before and monthly after diagnosis was a pragmatic design for good timing accuracy. Our pNLME timing approach is widely applicable to other infections with existing mathematical models. The present model could be used to simulate future HIV trials and may help estimate protective thresholds from the recently completed antibody-mediated prevention trials.

description: Spin-changing collisions in trapped Fermi gases may acquire a resonant character due to the compensation of quadratic Zeeman effect and trap energy. These resonances are absent in spinor condensates and pseudo-spin-1/2 Fermi gases, being a characteristic feature of high-spin Fermi gases that allows spinor physics at large magnetic fields. We analyze these resonances in detail for the case of lattice spinor fermions, showing that they permit to selectively target a spin-changing channel while suppressing all others. These resonances allow for the controlled creation of non-trivial quantum superpositions of many-particle states with entangled spin and trap degrees of freedom, which remarkably are magnetic-field insensitive. Finally, we show that the intersite tunneling may lead to a quantum phase transition described by an effective quantum Ising model.

Moreover, we show that a taut sutured compression body has a finite-sheeted cover with a depth one taut-oriented foliation.

description: Time-series data from multiple gravitational wave (GW) detectors can be linearly combined to form a null-stream, in which all GW information will be cancelled out. This null-stream can be used to distinguish between actual GW triggers and spurious noise transients in a search for GW bursts using a network of detectors. The biggest source of error in the null-stream analysis comes from the fact that the detector data are not perfectly calibrated. In this paper, we present an implementation of the null-stream veto in the simplest network of two co-located detectors. The detectors are assumed to have calibration uncertainties and correlated noise components. We estimate the effect of calibration uncertainties in the null-stream veto analysis and propose a new formulation to overcome this. This new formulation is demonstrated by doing software injections in Gaussian noise.

Cholesterol synthesis in type III hyperlipoproteinemic and non-hyperlipidemic individuals
Creators: name: Dendy, Shauneen Marguerite
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this study was to investigate whether increased endogenous cholesterol synthesis contributes to the elevated plasma cholesterol levels observed in type III hyperlipoproteinemia (type III HLP). Eight apolipoprotein (apo) E2 subjects with type III HLP and 8 apo E2 non-hyperlipidemic control subjects (controls) were given a priming bolus dose of deuterium oxide (D₂O) (0.7 g D₂O/kg body H2O). Daily M1 (central) pool free cholesterol fractional synthetic rate (FSR) was calculated as the incorporation rate of deuterium from body water into plasma free cholesterol. Blood samples were collected one half hour prior to, and at 12 hour intervals over 48 hours following, the bolus D₂O dose. Drinking water labelled at 1.4 and 0.7 g D₂O/liter H₂O was given on the fed and fasted days, respectively. Over 0-24 hours, subjects consumed a diet of three isocaloric meals which, in composition, approximated average North American intakes. Subjects fasted over 24-48 hours. The deuterium enrichment of plasma free cholesterol and plasma water was determined by isotope ratio mass spectrometry. When all subjects were included, mean (±SEM) free cholesterol overall FSR in type III HLPs (0.031 ± 0.006 per day) was not significantly different from controls (0.037 ± 0.004 per day). Estimated Ml total cholesterol pool size in type III HLPs (26.1 ± 1.9 g) and controls (24.9 ± 0.6 g) was not significantly different. When free cholesterol net synthesis was calculated as the absolute amount of cholesterol synthesized per day, based on Ml total cholesterol pool size, overall free cholesterol net synthesis in type III HLPs (0.304 ± 0.034 g/day) was not significantly different from controls (0.364 ± 0.035 g/day). When all subjects were included, overall free cholesterol FSR and overall free cholesterol net synthesis were significantly greater (p<0.001) in the fed (0.066 ± 0.006 day⁻¹ and 0.655 + 0.048 g/day, respectively) as compared to the fasted state (0.001 ± 0.004 day⁻¹ and 0.010 ± 0.037 g/day, respectively). In the fed state, type III HLPs tended to synthesize cholesterol at a lower rate and in a lower absolute amount as compared to controls, while the reverse was observed in the fasted state. These results suggest that: (1) the elevated plasma cholesterol levels observed in type III HLPs are not due to excess de novo cholesterol synthesis; (2) fasting significantly reduces cholesterol synthesis from the fed state.
On the nature of Seyfert galaxies with high [OIII]5007 blueshifts

description: We have studied the properties of Seyfert galaxies with high [OIII]5007 blueshifts (`blue outliers'), originally identified because of their strong deviation from the M_BH - sigma relation of normal, narrow-line Seyfert 1 (NLS1) and broad-line Seyfert 1 (BLS1) galaxies. These blue outliers turn out to be important test-beds for models of the narrow-line region (NLR), for mechanisms of driving large-scale outflows, for links between NLS1 galaxies and radio galaxies, and for orientation-dependent NLS1 models. We report the detection of a strong correlation of line blueshift with ionization potential in each galaxy, including the measurement of coronal lines with radial velocities up to 500--1000 km/s. All [OIII] blue outliers have narrow widths of their broad Balmer lines and high Eddington ratios. While the presence of non-shifted low-ionization lines signifies the presence of a classical outer quiescent NLR in blue outliers, we also report the absence of any second, non-blueshifted [OIII] component from a classical inner NLR. These results place tight constraints on NLR models. We favor a scenario in which the NLR clouds are entrained in a decelerating wind which explains the strong stratification and the absence of a zero-blueshift inner NLR of blue outliers. The origin of the wind remains speculative at this time (collimated radio plasma, thermal winds, radiatively accelerated clouds). It is perhaps linked to the high Eddington ratios of blue outliers. Similar, less powerful winds could be present in all Seyfert galaxies, but would generally only affect the coronal line region (CLR), or level off even before reaching the CLR. Similarities between blue outliers in NLS1 galaxies and (compact) radio sources are briefly discussed.

description: We study the distance dependence of the rate of electronic excitation energy transfer from a dye molecule to a metal nanoparticle. Using the spherical jellium model, we evaluate the rates corresponding to the excitation of l = 1, 2, and 3 modes of the nanoparticle. Our calculation takes into account both the electron-hole pair and the plasmon excitations of the nanoparticle. The rate follows conventional R^-6 dependence at large distances while small deviations from this behavior are observed at shorter distances. Within the framework of the jellium model, it is not possible to attribute the experimentally observed d^-4 dependence of the rate to energy transfer to plasmons or e-h pair excitations.

description: We study the properties of quantum entanglement and teleportation in the background of stationary and rotating curved space-times with extra dimensions. We show that a maximally entangled Bell state in an inertial frame becomes less entangled in curved space due to the well-known Hawking-Unruh effect. The degree of entanglement is found to be degraded with increasing the extra dimensions. For a finite black hole surface gravity, the observer may choose higher frequency mode to keep high level entanglement. The fidelity of quantum teleporation is also reduced because of the Hawking-Unruh effect. We discuss the fidelity as a function of extra dimensions, mode frequency, black hole mass and black hole angular momentum parameter for both bosonic and fermionic resources.

The effects of clomiphene citrate on ovarian function in rats
Creators: name: Feng, Tian Bin
Publisher: name: University of British Columbia
Year: 2010

description: In the present study, the effects of clomiphene citrate (CC) on ovulation, ovarian growth and ovarian steroidogenesis were examined. Ovulation in rats in response to PMSG was completely blocked by administration of three daily treatments of 1.0 mg CC/rat, but was restored by administration of hCG as a preovulatory LH surge substitute. When the number of treatment days was reduced to two days, 1.0 mg of CC enhanced ovulation in response to PMSG, whereas treatment for one day with the same dose of CC did not affect ovulation. The effects of CC on ovulation appear to be dose-dependent. The effects of CC on ovarian growth were similar to the effects of CC on ovulation. The ovarian growth induced by PMSG was inhibited by high doses of CC, while a lower dose had no effect. The inhibition of ovarian growth in terms of ovarian weight by a high dose of CC was restored by hCG given as a preovulatory LH surge. Treatment duration with CC appears to have an important influence on ovarian growth. Three daily treatments with high doses of CC significantly inhibited ovarian growth. However, when the number of treatment days was reduced from three to two, the opposite results were obtained in that CC significantly stimulated ovarian growth. The effects of CC on ovarian steroidogenesis in response to PMSG were dose-dependent. A higher dose of CC significantly stimulated estradiol-17β biosynthesis. Clomiphene citrate did not show any inhibitory effects on progesterone production. Progesterone production was stimulated by hCG in CC treated rats. Lower doses of CC stimulated progesterone and androgen production. Further studies on this are necessary. Histological examination of the ovary revealed that CC selectively inhibited the development of nondominant follicles. The dominant follicles were unaffected as for they were able to develop to the mature stage. These results suggest that the effects of CC on ovulation, ovarian growth and ovarian steroidogenesis are dose-dependent and affected by treatment duration. Clomiphene citrate is assumed to exert its action via a gonadotropic mechanism.

description: We define the ``Pulse Synchronization'' problem that requires nodes to achieve tight synchronization of regular pulse events, in the settings of distributed computing systems. Pulse-coupled synchronization is a phenomenon displayed by a large variety of biological systems, typically overcoming a high level of noise. Inspired by such biological models, a robust and self-stabilizing Byzantine pulse synchronization algorithm for distributed computer systems is presented. The algorithm attains near optimal synchronization tightness while tolerating up to a third of the nodes exhibiting Byzantine behavior concurrently. Pulse synchronization has been previously shown to be a powerful building block for designing algorithms in this severe fault model. We have previously shown how to stabilize general Byzantine algorithms, using pulse synchronization. To the best of our knowledge there is no other scheme to do this without the use of synchronized pulses.

In our approach we take into account a QCD description of the nucleon structure functions as well as a number of basic nuclear effects including nuclear shadowing, Fermi motion and binding, nuclear pion excess and off-shell correction to bound nucleon structure functions. These effects prove to be important in the studies of charged-lepton deep-inelastic scattering. We discuss similarities and dissimilarities in the calculation of nuclear effects for charged-lepton and neutrino scattering caused by nonconserved axial current in neutrino scattering. We examine the Adler and the Gross-Llewellyn-Smith sum rules for nuclear structure functions and find a remarkable cancellation between nuclear shadowing and off-shell corrections in these sum rules. We present calculations of differential cross sections for inclusive neutrino and antineutrino scattering in comparison with recent data on different target materials.

description: The kinetics of HCP-BCC structure phase transition is studied by precise pressure measurement technique in 4He crystals of different quality. An anomalous pressure behavior in bad quality crystals under constant volume conditions is detected just after HCP-BCC structure phase transition. A sharp pressure drop of 0.2 bar was observed at constant temperature. The subsequent pressure kinetics is a non-monotonic temperature function. The effect observed can be explained if we suppose that microscopic liquid droplets appear on the HCP-BCC interphase region in bad quality crystals. After the interphase region disappearance, these droplets are crystallized with pressure reduction. It is shown that this effect is absent in high quality thermal-treated crystals.

description: Социальное предпринимательство в России постепенно становится привычной практикой, в которой, впрочем, остаются свои особенности и проблемы. Фокус-групповое социологическое исследование, проведенное в 2017-2018 гг. Центром инноваций социальной сферы Новгородской области в целях определения набора типовых (отличающих) характеристик субъекта социального предпринимательства региона, выполненное самими субъектами социального предпринимательства, было представлено двумя группами социальных предпринимателей, осуществляющих (планирующих осуществлять) деятельность в различных сферах оказания социальных услуг населению на территории Новгородской области. Обработка данных велась на основе анализа написанных по транскриптам групповых обсуждений; рассчитывались комплексные показатели, включающие следующие составляющие «портрета» социального предпринимателя: ценностные ориентации и общественная активность, социальная ответственность, склонность к деятельности, направленной на решение социальных проблем, инновационность мышления и деятельности,
экономическая эффективность бизнеса. Так, выявлено, что социальные предприниматели Новгородской области проявляют открытость по отношению к людям и обладают высоким уровнем осознанного социального доверия. Свою
миссию они видят в творении добра и воплощении его в жизнь, выравнивании общества, изменении общества к лучшему, улучшении мира, изменении жизни вокруг себя. Подавляющее большинство респондентов понимают, что от предпринимателей многое зависит, и они должны наряду с государством и общественными организациями участвовать в решении актуальных социальных проблем.

description: (abridged) We perform 12 extremely high resolution adaptive mesh refinement cosmological hydrodynamic simulations of Population III star formation in a Lambda CDM universe, varying the box size and large-scale structure, to understand systematic effects in the formation of primordial protostellar cores. We find results that are qualitatively similar to those observed previously. We observe that the threshold halo mass for formation of a Population III protostar does not evolve significantly with time in the redshift range studied (33 > z > 19) but exhibits substantial scatter due to different halo assembly histories: Halos which assembled more slowly develop cooling cores at lower mass than those that assemble more rapidly, in agreement with Yoshida et al. (2003). We do, however, observe significant evolution in the accretion rates of Population III protostars with redshift, with objects that form later having higher maximum accretion rates, with a variation of two orders of magnitude (10^-4 - 10^-2 Msolar/year). This can be explained by considering the evolving virial properties of the halos with redshift and the physics of molecular hydrogen formation at low densities. Our result implies that the mass distribution of Population III stars inferred from their accretion rates may be broader than previously thought, and may evolve with redshift. Finally, we observe that our collapsing protostellar cloud cores do not fragment, consistent with previous results, which suggests that Population III stars which form in halos of mass 10^5 - 10^6 Msun always form in isolation.

description: В статье исследуется развитие железнодорожной инфраструктуры и его связь с общим развитием регионов Северо-западного федерального округа Российской Федерации (СЗФО) посредством использования трендового анализа и прогноза динамики на среднесрочный период. В качестве показателя, отражающего взаимосвязь развития железнодорожной инфраструктуры с уровнем регионального развития, используется сумма валового регионального
продукта (ВРП), приходящаяся на 1 км железнодорожных путей. В ходе исследования выявлены две тенденции развития данного показателя: линейная и нелинейная (экспоненциальная). Линейный характер развития наблюдается в
Республике Коми, Архангельской, Калининградской, Ленинградской, Новгородской и Псковской областях; нелинейный – в Республике Карелия, Вологодской и Мурманской областях, а также в г. Санкт-Петербурге. Регионы, входящие в
состав СЗФО, по уровню прироста исследуемого показателя разделились на три группы: регионы со сверхвысоким приростом ВРП на 1 км железнодорожных путей, регионы с высоким приростом ВРП на 1 км железнодорожных путей
и регионы со средним приростом. В результате совмещения двух критериев, примененных к показателю суммы ВРП, приходящейся на 1 км железнодорожных путей, регионы СЗФО разделились на три группы: с неравномерным и
очень высоким ростом суммы ВРП, приходящейся на 1 км железнодорожных путей – г. Санкт-Петербург; с высоким нелинейным ростом показателя – Республика Карелия, Вологодская и Мурманская области; со средним линейным
ростом показателя – Республика Коми, Архангельская, Калининградская, Ленинградская, Новгородская, Псковская области. В зависимости от характера развития исследуемого показателя может быть применена как количественная, так и качественная реконструкция железнодорожной инфраструктуры СЗФО с целью развития рынка регионов.
The effects of temperature change and lung expansion on lung liquid production in in vitro preparations of lungs from fetal guinea pigs (Cavia porcellus)

description: This study examined the effects of lung expansion and changes in temperature on fluid movement by the lungs in the initial period after birth. In addition, experiments with amiloride support the belief that fluid reabsorption acts via a sodium transport mechanism. Lungs from fetal guinea pigs (56-67 days of gestation) were supported in vitro for three hours, and lung liquid production rates were measured using a dye dilution technique. The average production rate in the first hour of untreated preparations was 1.30 ±0.22 ml/kg body weight per hour, and this did not change significantly during the remainder of the experiment (n=30). This rate is comparable to secretion rates previously reported from chronically catheterized sheep. In 36 further preparations, the lungs were transferred from 37°C to fresh Krebs-Hanseleit saline at one of the following temperatures, for one hour (an ABA design): (a) 29°C; (b) 32°C; (c) 34°C; (d) 35°C; (e) 36°C; (f) 39°C. In all cases, the temperature change resulted in an immediate and significant fall in secretion. All lungs showed a tendency towards recovery when returned to starting conditions, except those subjected to a temperature increase. Reductions of 2-3°C, those normally seen in the delivery room, had the greatest effect and caused not only a decrease in secretion, but promoted fluid reabsorption. Amiloride at 10⁻⁶M had no effect on control preparations, but completely blocked the reabsorption stimulated by a temperature drop of 2°C. Expansion of the lungs, which occurs naturally as a newborn attempts to take its first breaths, was also examined. Thirty fetal lungs were expanded by one of the following amounts: (a) 18%; (b) 31%; (c) 43%; (d) 50%; (e) 72%. All expansions resulted in a significant fall in secretion rate, with the effect being proportional to the degree of expansion. Amiloride at 10⁻⁶M again blocked the strong reabsorption occurring with 70% expansion. Further studies investigated the possibility that expansion causes reabsorption via the local release of a substance occurring in the lungs. When one set of lungs was expanded in the presence of a second, unexpanded set, both showed a significant decrease in secretion, suggesting that the expanded lung had released some factor which affected the otherwise untreated lung. However, studies with α- and β- adrenergic blockers showed that it is unlikely the expanded lung was liberating either adrenaline or nor-adrenaline. The results of this study show that two changes which are likely to occur in the period immediately after birth, namely a 2-3°C decrease in core temperature, and lung expansion, may be important in promoting the vital reabsorption of fluid. They suggest that expansion may release substances locally in the lungs which stimulate this reabsorption, and that the fluid is removed from the potential air spaces via sodium transport mechanisms.

description: Aims. We present the first long-term pulse profile study of the X-ray pulsar SAX J2103.5+4545. Our main goal is to study the pulse shape correlation either with luminosity, time or energy. Methods. This Be/X-ray binary system was observed from 1999 to 2004 by RXTE PCA, and by INTEGRAL from 2002 to 2005, during the Performance and Verification (PV) phase and the Galactic Plane Scan survey (GPS). X-ray pulse profiles were obtained in different energy ranges. The long-term spectral variability of this source is studied. The long-term flux, frequency and spin-up rate histories are computed. A new set of orbital parameters are also determined. Results. The pulse shape is complex and highly variable either with time or luminosity. However, an energy dependence pattern was found. Single, double, triple or even quadruple peaks pulse profile structure was obtained. It was confirmed that SAX J2103.5+4545 becomes harder when the flux is higher. The new orbital solution obtained is: P_orb= 12.66528+-0.00051 days, e = 0.401+-0.018, w = 241.36+-2.18 and a_xsin i = 80.81+-0.67 lt-s.
