The Future Can Be Better: Young People And The Marawi Siege
Young people are deeply implicated in the Marawi siege. Many commentaries and studies view them in either of two ways. On the one hand, they are the sector characterized as most vulnerable to radicalization. Researchers focus on the factors that lead them to violent extremism (Casey and Pottebaum 2018). But on the other hand, they are also characterized as passive victims needing relief and protection (Haynes and Tanner 2015). While these depictions may be legitimate in their own ways, they contradict each other. They are either perpetrators of violence or its victims. But they also share important similarities. These depictions derive from deep concerns about the wellbeing of young people in conflict situations. This sentiment is valid because they ought to be enjoying their youth and discovering their talents and abilities at school. And yet both depictions also share a problematic assumption. That they are either prone to violence or victims of conflict frames young people as a social problem at the same time, taking them as a social problem evidently carries a moral undertone: While some may be driven by a sense of righteous indignation, some others may be carried away by their ignorance (Hughes 2016). These frames, taken together, are blind to the youths’ potential contributions as effective agents of change, especially in post-conflict reconstruction. Research shows that although it may force young people to take on adult roles for which they are unprepared, conflict does not necessarily cripple their abilities to see into the future (Schwartz 2010). They do have stories and aspirations to share, some of which remain rooted in idealism and hope that tomorrow will be better. This is the basis of our ongoing study that documents the narratives of young people before, during, and after the Marawi siege. Our project, funded by the Department of Science and Technology (DOST), involves interviewing Muslim, Christian, and Lumad youths. We are also working with Reemar Alonsagay, a recent graduate of MSU – Marawi. We wish to spell out the importance of our research and some of our findings in this Perspectives piece

High temperature decomposition and age hardening of single-phase wurtzite TiAlN thin films grown by cathodic arc deposition
We investigated the high temperature decomposition behavior of wurtzite phase
TiAlN films using experimental methods and first-principles
calculations. Single phase metastable wurtzite TiAlN (x = 0.65,
0.75, 085 and 0.95) solid solution films were grown by cathodic arc deposition
using low duty cycle pulsed substrate-bias voltage. First-principles calculated
elastic constants of the wurtzite TiAlN phase show a strong
dependence on alloy composition. The predicted phase diagram shows a
miscibility gap with an unstable region. High resolution scanning transmission
electron microscopy and chemical mapping demonstrate decomposition of the films
after high temperature annealing (950C), which resulted in nanoscale
chemical compositional modulations containing Ti-rich and Al-rich regions with
coherent or semi coherent interfaces. This spinodal decomposition of the
wurtzite film causes age hardening of 1-2 GPa
LEVEL OF STRESS AND COPING MECHANISMS OF COLLEGE STUDENTS IN THE ONLINE DISTANCE LEARNING
This research aimed to investigate the level of stress and coping mechanisms of the College of Education (CED) students at Notre Dame of Midsayap College (NDMC) in online distance learning. This study also aimed to determine if there is a significant difference in the level of stress of the respondents when grouped according to sex and age. A descriptive research design was undertaken to assess the respondents' level of stress and coping mechanisms. The data were subjected to appropriate statistical tools utilized in the study such as frequency count, percentage distribution, weighted mean, and one-way ANOVA. Based on the major findings of the study, it can be concluded that students experience stress during their online distance learning brought upon by the COVID-19 pandemic. Bad internet connection, financial problems, disturbances in academic life, improper learning environment, tiredness, and irritation in performing their schoolwork are the significant causes of the stress of the students in dealing with their online distance learning. It was also found that they have different coping mechanisms in dealing with stress in their online distance learning. Such coping mechanisms were praying or meditating, creating a conducive learning environment, thinking positively, and playing online games. It was determined that male respondents experienced more stress in online distance learning than female respondents. It was also noted that younger respondents experience more stress than older respondents. Article visualizations
Combined search for the standard model Higgs boson decaying to a bb pair using the full CDF data set
We combine the results of searches for the standard model Higgs boson based
on the full CDF Run II data set obtained from sqrt(s) = 1.96 TeV p-pbar
collisions at the Fermilab Tevatron corresponding to an integrated luminosity
of 9.45/fb. The searches are conducted for Higgs bosons that are produced in
association with a W or Z boson, have masses in the range 90-150 GeV/c^2, and
decay into bb pairs. An excess of data is present that is inconsistent with the
background prediction at the level of 2.5 standard deviations (the most
significant local excess is 2.7 standard deviations).Comment: To be published in Phys. Rev. Lett (v2 contains minor updates based

Shrinking a large dataset to identify variables associated with increased risk of Plasmodium falciparum infection in Western Kenya
Large datasets are often not amenable to analysis using traditional single-step approaches. Here, our general objective was to apply imputation techniques, principal component analysis (PCA), elastic net and generalized linear models to a large dataset in a systematic approach to extract the most meaningful predictors for a health outcome. We extracted predictors for Plasmodium falciparum infection, from a large covariate dataset while facing limited numbers of observations, using data from the People, Animals, and their Zoonoses (PAZ) project to demonstrate these techniques: data collected from 415 homesteads in western Kenya, contained over 1500 variables that describe the health, environment, and social factors of the humans, livestock, and the homesteads in which they reside. The wide, sparse dataset was simplified to 42 predictors of P. falciparum malaria infection and wealth rankings were produced for all homesteads. The 42 predictors make biological sense and are supported by previous studies. This systematic data-mining approach we used would make many large datasets more manageable and informative for decision-making processes and health policy prioritization
Observation of Exclusive Gamma Gamma Production in p pbar Collisions at sqrt{s}=1.96 TeV
We have observed exclusive \gamma\gamma production in proton-antiproton
collisions at \sqrt{s}=1.96 TeV, using data from 1.11 \pm 0.07 fb^{-1}
integrated luminosity taken by the Run II Collider Detector at Fermilab. We
selected events with two electromagnetic showers, each with transverse energy
E_T > 2.5 GeV and pseudorapidity |\eta| < 1.0, with no other particles detected
in -7.4 < \eta < +7.4. The two showers have similar E_T and azimuthal angle
separation \Delta\phi \sim \pi; 34 events have two charged particle tracks,
consistent with the QED process p \bar{p} to p + e^+e^- + \bar{p} by two-photon
exchange, while 43 events have no charged tracks. The number of these events
that are exclusive \pi^0\pi^0 is consistent with zero and is < 15 at 95% C.L.
The cross section for p\bar{p} to p+\gamma\gamma+\bar{p} with |\eta(\gamma)| <
1.0 and E_T(\gamma) > 2.5$ GeV is
2.48^{+0.40}_{-0.35}(stat)^{+0.40}_{-0.51}(syst) pb.Comment: 7 pages, 4 figure
Measurement of the Cross Section and Triple Gauge Couplings in Collisions at TeV
This Letter describes the current most precise measurement of the
production cross section as well as limits on anomalous couplings at a
center-of-mass energy of 1.96 TeV in proton-antiproton collisions for the
Collider Detector at Fermilab (CDF). candidates are reconstructed from
decays containing three charged leptons and missing energy from a neutrino,
where the charged leptons are either electrons or muons. Using data collected
by the CDF II detector (7.1 fb of integrated luminosity), 63 candidate
events are observed with the expected background contributing events.
The measured total cross section pb is in good
agreement with the standard model prediction of . The same sample
is used to set limits on anomalous couplings.Comment: Resubmission to PRD-RC after acceptance (27 July 2012
A search for resonant production of pairs in $4.8\ \rm{fb}^{-1}p\bar{p}\sqrt{s}=1.96\ \rm{TeV}$
We search for resonant production of tt pairs in 4.8 fb^{-1} integrated
luminosity of ppbar collision data at sqrt{s}=1.96 TeV in the lepton+jets decay
channel, where one top quark decays leptonically and the other hadronically. A
matrix element reconstruction technique is used; for each event a probability
density function (pdf) of the ttbar candidate invariant mass is sampled. These
pdfs are used to construct a likelihood function, whereby the cross section for
resonant ttbar production is estimated, given a hypothetical resonance mass and
width. The data indicate no evidence of resonant production of ttbar pairs. A
benchmark model of leptophobic Z \rightarrow ttbar is excluded with m_{Z'} <
900 GeV at 95% confidence level.Comment: accepted for publication in Physical Review D Sep 21, 201
