TL;DR: The T2K experiment has observed electron neutrino appearance in a muon neutrinos beam produced 295 km from the Super-Kamiokande detector with a peak energy of 0.6 GeV, corresponding to a significance of 7.3σ.
Abstract: The T2K experiment has observed electron neutrino appearance in a muon neutrino beam produced 295 km from the Super-Kamiokande detector with a peak energy of 0.6 GeV. A total of 28 electron neutrino events were detected with an energy distribution consistent with an appearance signal, corresponding to a significance of 7.3 sigma when compared to 4.92 +/- 0.55 expected background events. In the Pontecorvo-Maki-Nakagawa-Sakata mixing model, the electron neutrino appearance signal depends on several parameters including three mixing angles theta(12), theta(23), theta(13), a mass difference vertical bar Delta m(32)(2)vertical bar and a CP violating phase delta(CP). In this neutrino oscillation scenario, assuming vertical bar Delta m(32)(2)vertical bar = 2.4 x 10(-3) eV(2), sin theta(2)(23) = 0.5, and vertical bar Delta m(32)(2)vertical bar > 0 (vertical bar Delta m(32)(2)vertical bar <0), a best- fit value of sin2 theta(2)(13) = 0.140(- 0.032)(+0.038) (0.170(-0.037)(+0.045)) is obtained at delta(CP) = 0. When combining the result with the current best knowledge of oscillation parameters including the world average value of theta(13) from reactor experiments, some values of delta(CP) are disfavored at the 90% C.

TL;DR: This review discusses various enhancement technologies such as the use of ultrasounds for in-process nanoparticles dispersion and of processing aspects to reach optimal properties for using nanocomposites in the selected applications.
Abstract: For the last decades, nanocomposites materials have been widely studied in the scientific literature as they provide substantial properties enhancements, even at low nanoparticles content. Their performance depends on a number of parameters but the nanoparticles dispersion and distribution state remains the key challenge in order to obtain the full nanocomposites’ potential in terms of, e.g., flame retardance, mechanical, barrier and thermal properties, etc., that would allow extending their use in the industry. While the amount of existing research and indeed review papers regarding the formulation of nanocomposites is already significant, after listing the most common applications, this review focuses more in-depth on the properties and materials of relevance in three target sectors: packaging, solar energy and automotive. In terms of advances in the processing of nanocomposites, this review discusses various enhancement technologies such as the use of ultrasounds for in-process nanoparticles dispersion. In the case of nanocoatings, it describes the different conventionally used processes as well as nanoparticles deposition by electro-hydrodynamic processing. All in all, this review gives the basics both in terms of composition and of processing aspects to reach optimal properties for using nanocomposites in the selected applications. As an outlook, up-to-date nanosafety issues are discussed.

TL;DR: Primary outcomes included return of bowel function and ability to tolerate solid food, ambulation, suture removal, and duration of hospitalization and none of the secondary outcomes varied significantly between the 2 treatment groups.
Abstract: ContextSupplemental perioperative oxygen has been variously reported to halve
or double the risk of surgical wound infection.ObjectiveTo test the hypothesis that supplemental oxygen reduces infection risk
in patients following colorectal surgery.Design, Setting, and PatientsA double-blind, randomized controlled trial of 300 patients aged 18
to 80 years who underwent elective colorectal surgery in 14 Spanish hospitals
from March 1, 2003, to October 31, 2004. Wound infections were diagnosed by
blinded investigators using Centers for Disease Control and Prevention criteria.
Baseline patient characteristics, anesthetic treatment, and potential confounding
factors were recorded.InterventionsPatients were randomly assigned to either 30% or 80% fraction of inspired
oxygen (FIO2) intraoperatively and for 6 hours after
surgery. Anesthetic treatment and antibiotic administration were standardized.Main Outcome MeasuresAny surgical site infection (SSI); secondary outcomes included return
of bowel function and ability to tolerate solid food, ambulation, suture removal,
and duration of hospitalization.ResultsA total of 143 patients received 30% perioperative oxygen and 148 received
80% perioperative oxygen. Surgical site infection occurred in 35 patients
(24.4%) administered 30% FIO2 and in 22 patients
(14.9%) administered 80% FIO2 (P=.04). The risk of SSI was 39% lower in the 80% FIO2 group (relative risk [RR], 0.61; 95% confidence interval [CI], 0.38-0.98)
vs the 30% FIO2 group. After adjustment for important
covariates, the RR of infection in patients administered supplemental oxygen
was 0.46 (95% CI, 0.22-0.95; P = .04).
None of the secondary outcomes varied significantly between the 2 treatment
groups.ConclusionsPatients receiving supplemental inspired oxygen had a significant reduction
in the risk of wound infection. Supplemental oxygen appears to be an effective
intervention to reduce SSI in patients undergoing colon or rectal surgery.Trial RegistrationClinicalTrials.gov Identifier: NCT00235456

TL;DR: Tuning through the layered magnetic insulator CrI3 as a function of temperature and applied magnetic field is reported, electrically detect the magnetic ground state and interlayer coupling and observe a field-induced metamagnetic transition.
Abstract: Magnetic insulators are a key resource for next-generation spintronic and topological devices. The family of layered metal halides promises varied magnetic states, including ultrathin insulating multiferroics, spin liquids, and ferromagnets, but device-oriented characterization methods are needed to unlock their potential. Here, we report tunneling through the layered magnetic insulator CrI3 as a function of temperature and applied magnetic field. We electrically detect the magnetic ground state and interlayer coupling and observe a field-induced metamagnetic transition. The metamagnetic transition results in magnetoresistances of 95, 300, and 550% for bilayer, trilayer, and tetralayer CrI3 barriers, respectively. We further measure inelastic tunneling spectra for our junctions, unveiling a rich spectrum consistent with collective magnetic excitations (magnons) in CrI3.

TL;DR: It is concluded that Shh signaling, acting through the primary cilia, has a critical role in the expansion and establishment of postnatal hippocampal progenitors.
Abstract: Neural stem cells that continue to produce neurons are retained in the adult hippocampal dentate gyrus. The mechanisms by which embryonic neural progenitors expand and transform into postnatal neural stem cells, an essential process for the continual production of neurons throughout life, remain unknown. We found that radial astrocytes, the postnatal progenitors in the dentate gyrus, failed to develop after embryonic ablation of ciliary genes or Smoothened (Smo), an essential component for Sonic hedgehog (Shh) signaling. Postnatal dentate neurogenesis failed in these mutant mice, and the dentate gyrus became severely hypotrophic. In contrast, expression of a constitutively active Smo (SmoM2-YFP) resulted in a marked expansion of the dentate gyrus. Double-mutant analyses suggested that both wild-type Smo and SmoM2-YFP function through the primary cilia. We conclude that Shh signaling, acting through the primary cilia, has a critical role in the expansion and establishment of postnatal hippocampal progenitors.
