Seeking Treatment for PTSD: the Post 9/11 Service Member\u27s Experience

Posttraumatic-stress disorder (PTSD) remains one of the most pervasive health conditions to affect the 2.7 million United States service members deployed to Iraq and Afghanistan since 2001. Untreated and/or inadequately treated PTSD can further lead to an array of health risks including anxiety, depression, substance abuse, social and occupational impairments, poorer quality of physical health, decreased overall perception of quality of life, and increase the risk of suicide. Considering these risks, the Department of Veterans Affairs (VA) and Department of Defense (DoD) created the VA/DOD Clinical Practice Guidelines (CPGs) for the Management of PTSD and Acute Stress Reaction (ASR), highlighting the strongest evidence-based approaches to treatment for clinicians providing care for service members. The CPGs further outlines the importance of providing clients/patients with psychoeducation regarding PTSD and treatment options, offering a client-centered approach through a Shared Decision-Making Model (SDM), while also illustrating known barriers to treatment, and concerns regarding early termination. Successful implementation of the CPGs is expected to enhance assessment of client’s/patient’s needs and assist in determining and providing effective care. The number of veterans suffering with PTSD continues to be an alarming concern, one with life-threatening implications. While this concern is recognized among clinicians, statistics continue to highlight the vast number of those suffering with PTSD and PTSD related conditions, further pressing the need to explore additional ways to improve the efficacy of treatment. The purpose of this study is to explore the post 9/11 military population’s experience in seeking treatment, as reflected by the CPGs recommendations, while further exploring their views regarding ways to improve the efficacy of assessing and treating PTSD.

Some recent results on niche graphs

AbstractIn an earlier paper entitled “Niche graphs” written by Cable, Jones, Lundgren and Seager, niche graphs were introduced and examples were provided of graphs which have niche number 0, 1, 2, and ∞. However, no examples were found of a niche graph having finite niche number 3 or larger. We still have had no success in our efforts to find such a graph. Nevertheless we have gotten some interesting results. For example, we show in this paper that if there is such a graph, then there must be one which is connected. We also show that the niche number of a graph which has a finite niche number is ≤23|V(G)|. In addition we determine the niche number of all “wheel” graphs

Concept of Formation Length in Radiation Theory

The features of electromagnetic processes are considered which connected with finite size of space region in which final particles (photon, electron-positron pair) are formed. The longitudinal dimension of the region is known as the formation length. If some external agent is acting on an electron while traveling this distance the emission process can be disrupted. There are different agents: multiple scattering of projectile, polarization of a medium, action of external fields, etc. The theory of radiation under influence of the multiple scattering, the Landau-Pomeranchuk-Migdal (LPM) effect, is presented. The probability of radiation is calculated with an accuracy up to "next to leading logarithm" and with the Coulomb corrections taken into account. The integral characteristics of bremsstrahlung are given, it is shown that the effective radiation length increases due to the LPM effect at high energy. The LPM effect for pair creation is also presented. The multiple scattering influences also on radiative corrections in a medium (and an external field too) including the anomalous magnetic moment of an electron and the polarization tensor as well as coherent scattering of a photon in a Coulomb field. The polarization of a medium alters the radiation probability in soft part of spectrum. Specific features of radiation from a target of finite thickness include: the boundary photon emission, interference effects for thin target, multi-photon radiation. The experimental study of LPM effect is described. For electron-positron colliding beams following items are discussed: the separation of coherent and incoherent mechanisms of radiation, the beam-size effect in bremsstrahlung, coherent radiation and mechanisms of electron-positron creation.Comment: Revised review paper, 96 pages, 28 figures.

Testing Higgs models via the H±W∓ZH^\pm W^\mp Z vertex by a recoil method at the International Linear Collider

In general, charged Higgs bosons $H^\pm$ appear in non-minimal Higgs models. The $H^\pm W^\mp Z$ vertex is known to be related to the violation of the global symmetry (custodial symmetry) in the Higgs sector. Its magnitude strongly depends on the structure of the exotic Higgs models which contain higher isospin $SU(2)_L$ representations such as triplet Higgs bosons. We study the possibility of measuring the $H^\pm W^\mp Z$ vertex via single charged Higgs boson production associated with the $W^\pm$ boson at the International Linear Collider (ILC) by using the recoil method. The feasibility of the signal $e^+e^-\to H^\pm W^\mp \to \ell \nu jj$ is analyzed assuming the polarized electron and positron beams and the expected detector performance for the resolution of the two-jet system at the ILC. The background events can be reduced to a considerable extent by imposing the kinematic cuts even if we take into account the initial state radiation. For a relatively light charged Higgs boson whose mass $m_{H^\pm}$ is in the region of 120-130 GeV $< m_{H^\pm} < m_W+m_Z$, the $H^\pm W^\mp Z$ vertex would be precisely testable especially when the decay of $H^\pm$ is lepton specific. The exoticness of the extended Higgs sector can be explored by using combined information for this vertex and the rho parameter.Comment: 22 pages, 23 figure

b --> s g g decay in the two and three Higgs doublet models with CP violating effects

We study the decay width and CP-asymmetry of the inclusive process b--> s g g (g denotes gluon) in the three and two Higgs doublet models with complex Yukawa couplings. We analyse the dependencies of the differential decay width and CP-asymmetry to the s- quark energy E_s and CP violating parameter \theta. We observe that there exist a considerable enhancement in the decay width and CP asymmetry is at the order of 10^{-2}. Further, it is possible to predict the sign of C_7^{eff} using the CP asymmetry.Comment: 15 pages, 7 Figures (required epsf style

Genome Dynamics Are Influenced by Food Source in Allogromia laticollaris Strain CSH (Foraminifera)

Across the eukaryotic tree of life, genomes vary within populations and within individuals during their life cycle. Understanding intraspecific genome variation in diverse eukaryotes is key to elucidating the factors that underlie this variation. Here, we characterize genome dynamics during the life cycle of Allogromia laticollaris strain CSH, a member of the Foraminifera, using fluorescence microscopy and reveal extensive variation in nuclear size and DNA content. Both nuclear size and DNA content are tightly correlated across a 700-fold range in cell volume. In contrast to models in yeast where nuclear size is determined solely by cell size, the relationship in A. laticollaris CSH differs according to both life cycle stage and food source. Feeding A. laticollaris CSH a diet that includes algae results in a 2-fold increase in DNA content in reproductive cells compared with a diet of bacteria alone. This difference in DNA content likely corresponds to increased fecundity, as reproduction occurs through segregation of the polyploid nucleus into numerous daughter nuclei. Environmentally mediated variation in DNA content may be a widespread phenomenon, as it has been previously reported in the plant flax and the flagellate Euglena. We hypothesize that DNA content is influenced by food in other single-celled eukaryotes with ploidy cycles and that this genome flexibility may enable these eukaryotes to maximize fitness across changing environmental conditions

Higgs-photon associated production at hadron colliders

We present cross sections for the reactions $p\bar{p} --> H\gamma$ and $pp --> H\gamma$ arising from the subprocess $q\bar{q} --> H\gamma$. The calculation includes the complete one-loop contribution from all light quarks and is the main source of Higgs-photon associated production in hadron colliders. At Tevatron energies, the cross section is typically 0.1fb or less, while at LHC energies it can exceed 1.0fb
