E-Sakto: Lowering the Cardiovascular Risk of Patients with Hypertension and Diabetes Through Public–Private Partnership
Background: Technologically-enabled “whole-of-society” upgrading of a Rural Health Unit (RHU-Samboan) in data collection & records management, and determining the Cardiovascular risk score (CVD-RS) of patients with hypertension (± diabetes) was the aim of the e-Sakto program. Methodology: A descriptive study with fourcomponents: e-Sakto Sukod (right measurements), e-Sakto Suwat (right recording), e-Sakto Sibya (right information), and e-Sakto Serbisyo (right service). Samboan, a fifth-class municipality in Cebu, Philippines, is the pilot site. For data collection, this study used SHINE OS+ Electronic Medical Records (EMR) provided by SMARTCommunications, Inc. through public-private partnership (PPP). Furthermore, WHO WPR-B CVD-Risk Score was used to monitor the effect of using EMRs in relation to patients’ 10-year cardiovascular risks. Results: A competency check revealed that all health staff were adept at taking vital signs while only 59% (38/65) of healthvolunteers were competent. An inventory of the equipment revealed that 4 out of 15 barangays (villages) had appropriate tools for vital signs measurement. A municipal resolution institutionalized the use of EMR and linked Samboan with higher health institutions for referrals. Out of the total 414 hypertensive patients, 106 subjects underwent 3 monitoring visits. This resulted to a statistically-significant lowering of their 10-year cardiovascular risk score using the 3- and 5- point scoring CVD risk scale (p = 0.041; p = 0.001). Conclusion: e-Sakto made sure that the health workers were competent; equipment needed were available; EMR was institutionalized; and linkages were formed. The use of EMRs in monitoring hypertensive patients result insignificant reduction of their 10-year CVD risk.

Order parameter for the dynamical phase transition in Bose-Einstein condensates with topological modes
In a trapped Bose-Einstein condensate, subject to the action of an
alternating external field, coherent topological modes can be resonantly
excited. Depending on the amplitude of the external field and detuning
parameter, there are two principally different regimes of motion, with mode
locking and without it. The change of the dynamic regime corresponds to a
dynamic phase transition. This transition can be characterized by an effective
order parameter defined as the difference between fractional mode populations
averaged over the temporal period of oscillations. The behavior of this order
parameter, as a function of detuning, pumping amplitude, and atomic
interactions is carefully analyzed. A special attention is payed to numerical
calculations for the realistic case of a quadrupole exciting field and the
system parameters accessible in current experiments
Medium-modified evolution of multiparticle production in jets in heavy-ion collisions
The energy evolution of medium-modified average multiplicities and
multiplicity fluctuations in quark and gluon jets produced in heavy-ion
collisions is investigated from a toy QCD-inspired model. In this model, we use
modified splitting functions accounting for medium-enhanced radiation of gluons
by a fast parton which propagates through the quark gluon plasma. The leading
contribution of the standard production of soft hadrons is found to be enhanced
by the factor while next-to-leading order (NLO) corrections are
suppressed by , where the nuclear parameter accounts for
the induced-soft gluons in the hot medium. The role of next-to-next-to-leading
order corrections (NNLO) is studied and the large amount of medium-induced soft
gluons is found to drastically affect the convergence of the perturbative
series. Our results for such global observables are cross-checked and compared
with their limits in the vacuum and a new method for solving the second
multiplicity correlator evolution equations is proposed.Comment: 21 pages and 8 figures, typo corrections, references adde
Influence of processing temperature on quality and drying kinetics of a mixed fruit leather
A mixed fruit leather was developed with no chemical additives using five basic ingredients: pears, bananas, strawberries, honey, and lemon. The fruit puree was subjected to convective air drying at 60 ºC, 70 ºC, and 80 ºC and then packaged with a reversible metallized polypropylene foil and stored at 25 ºC for seven weeks. Different drying models were adjusted to the experimental data, with the Page model presenting the best fit. The obtained product was evaluated for nutritional and physical parameters. The values of phenolic compounds, water activity and water content were stable within the storage period, and the tested drying temperatures showed no impact. However, colour darkening occurred after the first month of storage. Regarding texture, adhesiveness did not seem to have a clear pattern over storage. The higher values of hardness and chewiness obtained at 60 ºC in comparison to 80 ºC are probably associated with the slightly lower water activity of the batches produced at 60 ºC. This natural fruit leather that combines the benefits of different fruits can be an option for the increasing consumers’ demand for healthier and more natural snacks.info:eu-repo/semantics/publishedVersio
A New Empirical Model for the Structural Analysis of Early-type Galaxies and a Critical Review of the Nuker Model
The Nuker law was designed to match the inner few (~3-10) arcseconds of
predominantly nearby (< 30 Mpc) early-type galaxy light-profiles; it was never
intended to describe an entire profile. The Sersic model, on the other hand,
was developed to fit the entire profile; however, due to the presence of
partially depleted galaxy cores, the Sersic model cannot always describe the
very inner region. We have therefore developed a new empirical model consisting
of an inner power-law, a transition region, and an outer Sersic model to
connect the inner and outer structure of elliptical galaxies. Moreover, the
stability of the Nuker model parameters are investigated. Surprisingly, none
are found to be stable quantities; all are shown to vary systematically with a
profile's fitted radial extent, and often by more than 100%. Considering
elliptical galaxies spanning a range of 7.5 magnitudes, the central stellar
density of the underlying host galaxy is observed to increase with galaxy
luminosity until the onset of core formation, detected only in the brightest
elliptical galaxies. We suggest that the so-called ``power-law'' galaxies may
actually be described by the Sersic model over their entire radial range
Analytic Bethe Ansatz for 1-D Hubbard model and twisted coupled XY model
We found the eigenvalues of the transfer matrices for the 1-D Hubbard model
and for the coupled XY model with twisted boundary condition by using the
analytic Bethe Ansatz method. Under a particular condition the two models have
the same Bethe Ansatz equations. We have also proved that the periodic 1-D
Hubbard model is exactly equal to the coupled XY model with nontrivial twisted
boundary condition at the level of hamiltonians and transfer matrices.Comment: 22 pages, latex, no figure
The type N Karlhede bound is sharp
We present a family of four-dimensional Lorentzian manifolds whose invariant
classification requires the seventh covariant derivative of the curvature
tensor. The spacetimes in questions are null radiation, type N solutions on an
anti-de Sitter background. The large order of the bound is due to the fact that
these spacetimes are properly , i.e., curvature homogeneous of order 2
but non-homogeneous. This means that tetrad components of are constant, and that essential coordinates first appear as
components of . Covariant derivatives of orders 4,5,6 yield one
additional invariant each, and is needed for invariant
classification. Thus, our class proves that the bound of 7 on the order of the
covariant derivative, first established by Karlhede, is sharp. Our finding
corrects an outstanding assertion that invariant classification of
four-dimensional Lorentzian manifolds requires at most .Comment: 7 pages, typos corrected, added citation and acknowledgemen
Structural changes during air drying of fruits and vegetables: a review
This work aims at reviewing structural changes occurring in convective air drying of fruits and vegetables. These include changes in physical properties, such as volume, porosity and bulk and particle density, which directlyaffect textural attributes of the products. Models relating with water content physical properties are also summarised. At microscopic level, the phenomena observed byprevious authors is described, focusing on shrinkage. In particular, a new approach on modelling kinetics of microstructural modifications is presented. Although the air drying process is relatively well studied, there is a lack of research concerning changes in structural properties. Modelling mass transfer during drying frequently does not include those effects and, there has not been established a standard methodologyfor predictive purposes. Correlating microstructure, texture measurements and sensoryanalysis would be an attractive area to be exploited for drying processes of fruits and vegetables. Although this is a wide working field, much is still to be done
Generation of nonground-state Bose-Einstein condensates by modulating atomic interactions
A technique is proposed for creating nonground-state Bose-Einstein
condensates in a trapping potential by means of the temporal modulation of
atomic interactions. Applying a time-dependent spatially homogeneous magnetic
field modifies the atomic scattering length. An alternating modulation of the
scattering length excites the condensate, which, under special conditions, can
be transferred to an excited nonlinear coherent mode. It is shown that there
occurs a phase-transition-like behavior in the time-averaged population
imbalance between the ground and excited states. The application of the
suggested technique to realistic experimental conditions is analyzed and it is
shown that the considered effect can be realized for experimentally available
condensates.Comment: 6 pages, 2 figures, 1 tabl
