Snowmass Neutrino Frontier: Neutrino Interaction Cross Sections (NF06) Topical Group Report
2022
A thorough understanding of neutrino cross sections in a wide range of energies is crucial for the successful execution of the entire neutrino physics program. In order to extract neutrino properties, long-baseline experiments need an accurate determination of neutrino cross sections within their detector(s). Since very few of the needed neutrino cross sections across the energy spectrum are directly measured, we emphasize the need for theoretical input and indirect measurements such as electron scattering, which would complement direct measurements. In this report we briefly summarize the current status of our knowledge of the neutrino cross sections and articulate needs of the experiments…

New orbital ephemerides for the dipping source 4U 1323-619: Constraining the distance to the source
2016
4U 1323-619 is a low mass X-ray binary system that shows type I X-ray bursts and dips. The most accurate estimation of the orbital period is 2.941923(36) hrs and a distance from the source that is lower than 11 kpc has been proposed. We aim to obtain the orbital ephemeris, the orbital period of the system, as well as its derivative to compare the observed luminosity with that predicted by the theory of secular evolution. We took the advantage of about 26 years of X-ray data and grouped the selected observations when close in time. We folded the light curves and used the timing technique, obtaining 12 dip arrival times. We fit the delays of the dip arrival times both with a linear and a quad…
Noise Reduction and Gap Filling of fAPAR Time Series Using an Adapted Local Regression Filter
2014
Time series of remotely sensed data are an important source of information for understanding land cover dynamics. In particular, the fraction of absorbed photosynthetic active radiation (fAPAR) is a key variable in the assessment of vegetation primary production over time. However, the fAPAR series derived from polar orbit satellites are not continuous and consistent in space and time. Filtering methods are thus required to fill in gaps and produce high-quality time series. This study proposes an adapted (iteratively reweighted) local regression filter (LOESS) and performs a benchmarking intercomparison with four popular and generally applicable smoothing methods: Double Logistic (DLOG), sm…
Latest Developments and Results of Radiation Tolerance CMOS Sensors with Small Collection Electrodes
2020
The development of radiation hard Depleted Monolithic Active Pixel Sensors (DMAPS) targets the replacement of hybrid pixel detectors to meet radiation hardness requirements of at least 1.5e16 1 MeV neq/cm2 for the HL-LHC and beyond. DMAPS were designed and tested in the TJ180 nm TowerJazz CMOS imaging technology with small electrodes pixel designs. This technology reduces costs and provides granularity of 36.4x36.4 um2 with low power operation (1 uW/pixel), low noise of ENC < 20 e-, a small collection electrode (3 um) and fast signal response within 25 ns bunch crossing. This contribution will present the latest developments after the MALTA and Mini-MALTA sensors. It will illustrate the imp…
La posició dels lletraferits renaixencistes valencians davant els postulats de la filologia romànica sobre el valencià
2017
Aquest treball analitza la reacció dels erudits i escriptors valencians davant els postulats de la filologia romànica sobre el català entre els anys 1858 i 1906, agrupant-los segons les seues respostes al tema del nom i de la identitat filològica del català. A més, tractem de relacionar les posicions d'aquests valencians amb el conjunt del moviment reinaixencista i amb la consciència de comunitat lingüística compartida amb catalans, balears i nordcatalans. A partir de la meitat del Vuitcents els romanistes germànics funden la filologia romànica i constaten que el català és el nom de la llengua pròpia dels territoris de llengua catalana, diferent de l'occità i sense res a veure amb el llemos…
Diurnal Cycle Relationships between Passive Fluorescence, PRI and NPQ of Vegetation in a Controlled Stress Experiment
2017
In order to estimate vegetation photosynthesis from remote sensing observations; some critical parameters need to be quantified. From all absorbed light; the plant needs to release any excess that is not used for photosynthesis; by non-photochemical quenching; by fluorescence emission and unregulated thermal dissipation. Non-photochemical quenching (NPQ) processes are controlled photoprotective mechanisms which; once activated; strongly control the dynamics of photochemical efficiency. With illumination conditions increasing and decreasing during a diurnal cycle; photoprotection mechanisms needs to change accordingly. The goal of this work is to quantify dynamic NPQ; measured from active fl…

Amygdaloid projections to the ventral striatum in mice: direct and indirect chemosensory inputs to the brain reward system
2011
Rodents constitute good models for studying the neural basis of socio-sexual behaviour. Recent findings in mice have revealed the molecular identity of the some pheromonal molecules triggering intersexual attraction. However, the neural pathways mediating this basic socio-sexual behaviour remain elusive. Since previous work indicates that the dopaminergic tegmento-striatal pathway is not involved in pheromone reward, the present report explores alternative pathways linking the vomeronasal system with the tegmento-striatal system (the limbic basal ganglia) by means of tract-tracing experiments studying direct and indirect projections from the chemosensory amygdala to the ventral striato-pall…
Koulu ja seksuaalikasvatus sateenkaaren väreissä

Kuusela, Mia-Marja. 2016. Koulu ja seksuaalikasvatus sateenkaaren väreissä. Kasvatustieteen pro gradu -tutkielma. Jyväskylän yliopisto. Opettajankoulutuslaitos. 59 sivua. Pro gradu –tutkimuksessani tutkin millaisia ajatuksia seksuaali- ja sukupuolivähemmistöihin kuuluvilla nuorilla on koulun seksuaalikasvatuksesta. Tutkimuksen tarkoituksena oli selvittää millaisena he kokevat koulun seksuaalikasvatuksen sekä millaisena he näkevät opettajan roolin heidän sateenkaarinuoruudessaan. Tutkimukseni on kvalitatiivinen, jossa on käytetty vuonna 2014 kerättyä sekundaarista kirjoituskeruuaineistoa. Tutkimusaineiston analysoin laadullisen sisällönanalyysin avulla aineistolähtöisestiTutkimustuloksista i…
