description: The worldvolume theory of coincident M5-branes is expected to contain a nonabelian 2-form/nonabelian gerbe gauge theory that is a higher analog of self-dual Yang-Mills theory. But the precise details -- in particular the global moduli / instanton / magnetic charge structure -- have remained elusive. Here we deduce from anomaly cancellation a natural candidate for the holographic dual of this nonabelian 2-form field, under AdS7/CFT6-duality. We find this way a 7-dimensional nonabelian Chern-Simons theory of String 2-connection fields, which, in a certain higher gauge, are given locally by non-abelian 2-forms with values in an affine Kac-Moody Lie algebra. We construct the corresponding action functional on the entire smooth moduli 2-stack of field configurations, thereby defining the theory globally, at all levels and with the full instanton structure, which is nontrivial due to the twists imposed by the quantum corrections. Along the way we explain some general phenomena of higher nonabelian gauge theory that we need.

description: For a class of nonequilibrium systems, called driven lattice gases, we study what happens when two systems are kept in contact and allowed to exchange particles with the total number of particles conserved. Both for attractive and repulsive nearest-neighbor interactions among particles and for a wide range of parameter values, we find that, to a good approximation, one could define an intensive thermodynamic variable, like equilibrium chemical potential, which determines the final steady state for two initially separated driven lattice gases brought into contact. However, due to nontrivial contact dynamics, there are also observable deviations from this simple thermodynamic law. To illustrate the role of the contact dynamics, we study a variant of the zero range process and discuss how the deviations could be explained by a modified large deviation principle. We identify an additional contribution to the large deviation function, which we call the excess chemical potential, for the variant of the zero range process as well as the driven lattice gases. The excess chemical potential depends on the specifics of the contact dynamics and is in general a-priori unknown. A contact dependence implies that even though an intensive variable may equalize, the zeroth law could still be violated.

description: Vicious assaults, malware, and various ransomware pose a cybersecurity threat, causing considerable damage to computer structures, servers, and mobile and web apps across various industries and businesses. These safety concerns are important and must be addressed immediately. Ransomware detection and classification are critical for guaranteeing rapid reaction and prevention. This study uses the XGBoost classifier and Random Forest (RF) algorithms to detect and classify ransomware attacks. This approach involves analyzing the behaviour of ransomware and extracting relevant features that can help distinguish between different ransomware families. The models are evaluated on a dataset of ransomware attacks and demonstrate their effectiveness in accurately detecting and classifying ransomware. The results show that the XGBoost classifier, Random Forest Classifiers, can effectively detect and classify different ransomware attacks with high accuracy, thereby providing a valuable tool for enhancing cybersecurity.

description: Despite many tests, even the Minimal Manifest Left-Right Symmetric Model (MLRSM) has never been ultimately confirmed or falsified. LHC gives a new possibility to test directly the most conservative version of left-right symmetric models at so far not reachable energy scales. If we take into account precise limits on the model which come from low energy processes, like the muon decay, possible LHC signals are strongly limited through the correlations of parameters among heavy neutrinos, heavy gauge bosons and heavy Higgs particles. To illustrate the situation in the context of LHC, we consider the "golden" process $pp \to e^+ N$. For instance, in a case of degenerate heavy neutrinos and heavy Higgs masses at 15 TeV (in agreement with FCNC bounds) we get $σ(pp \to e^+ N)>10$ fb at $\sqrt{s}=14$ TeV which is consistent with muon decay data for a very limited $W_2$ masses in the range (3008 GeV, 3040 GeV). Without restrictions coming from the muon data, $W_2$ masses would be in the range (1.0 TeV, 3.5 TeV). Influence of heavy Higgs particles themselves on the considered LHC process is negligible (the same is true for the light, SM neutral Higgs scalar analog). In the paper decay modes of the right-handed heavy gauge bosons and heavy neutrinos are also discussed. Both scenarios with typical see-saw light-heavy neutrino mixings and the mixings which are independent of heavy neutrino masses are considered. In the second case heavy neutrino decays to the heavy charged gauge bosons not necessarily dominate over decay modes which include only light, SM-like particles.

description: We introduce two kinds of structures, called v-structures and t-structures, on biquandles. These structures are used for colorings of diagrams of virtual links and twisted links such that the numbers of colorings are invariants. Given a biquandle or a quandle, we give a method of constructing a biquandle with these structures. Using the numbers of colorings, we show that Bourgoin's twofoil and non-orientable virtual $m$-foils do not represent virtual links.

description: Electron scattering Coulomb form factors for the single-particle quadrupole transitions in $p$-shell $^{10}$B nucleus have been studied. Core polarization effects are included through a microscopic theory that includes excitations from the core orbits up to higher orbits with 2$\hbar$$ω$ excitations. The modified surface delta interaction (MSDI) is employed as a residual interaction. The effect of core polarization is found essential in both the transition strengths and momentum transfer dependence of form factors, and gives a remarkably good agreement with the measured data with no adjustable parameters.

The optical metrology system consists of a laser with modulator, four Mach-Zehnder interferometers, a phase-meter and a digital processing unit for data analysis. The digital loop design has the advantage of easy and flexible controller implementation and loop calibration, automated and flexible locking and resetting, and improved performance over analogue circuitry. Using the practical ability of our system to modulate the laser frequency allows us to accurately determine the open loop transfer function and other system properties. Various noise sources and their impact on system performance are investigated in detail.

description: The antiProton Unstable Matter Annihilation experiment (PUMA) at CERN aims at investigating the nucleon composition in the matter density tail of radioactive as well as stable isotopes by use of low-energy antiproton-nucleon annihilation processes. For this purpose, antiprotons provided by the Extra Low ENergy Antiproton (ELENA) facility will be trapped together with the ions of interest. While exotic ions will be obtained by the Isotope mass Separator On-Line DEvice (ISOLDE), stable ions will be delivered from an offline ion source setup designed for this purpose. This allows the proposed technique to be applied to a variety of stable nuclei and for reference measurements. For beam purification, the ion source setup includes a multi-reflection time-of-flight mass spectrometer (MR-ToF MS). Supported by SIMION simulations, an earlier MR-ToF MS design has been modified to meet the requirements of PUMA. During commissioning of the new MR-ToF device with Ar$^+$ ions, mass resolving powers in excess of 50,000 have been obtained after 150 revolutions, limited by the chopping of the continuous beam from an electron impact ionisation source.

Chatter stability of turning and milling with process damping
Creators: name: Eynian, Mahdi
Publisher: name: University of British Columbia
Year: 2010

description: The prediction of chatter instability in machining steel and thermal-resistant alloys at low ‎cutting speeds has been difficult due to unknown process damping contributed by the ‎contact mechanism between tool flank and wavy surface finish. This thesis presents ‎modeling and measurement of process damping coefficients, and the prediction of chatter ‎stability limits for turning and milling operations at low cutting speeds. ‎ The dynamic cutting forces are separated into regenerative and process damping ‎components. The process damping force is expressed as a product of dynamic cutting ‎force coefficient and the ratio of vibration and cutting velocities. It is demonstrated that ‎the dynamic cutting coefficient itself is strongly affected by flank wear land. In ‎measurement of dynamic cutting forces, the regenerative force is eliminated by keeping ‎the inner and outer waves parallel to each other while the tool is oscillated using a piezo ‎actuator during cutting. ‎ Classical chatter stability laws cannot be used in stability prediction for general turning ‎with tools cutting along non-straight cutting edges; where the direction and magnitude of ‎the dynamic forces become dependent on the depth of cut and feed-rate. A new dynamic ‎cutting force model of regeneration of chip area and process damping, which considers ‎tool nose radius, feed–rate, depth of cut, cutting speed and flank wear is presented. The ‎chatter stability is predicted in the frequency domain using Nyquist stability criterion.‎ The process damping is considered in a new dynamic milling model for tools having ‎rotating but asymmetric dynamics. The flexibility of the workpiece is studied in a fixed ‎coordinate system but the flexibility of the tool is studied in a rotating coordinate system. ‎The periodic directional coefficients are averaged, and the stability of the dynamic ‎milling system is determined in the frequency domain using Nyquist stability criterion. ‎ The experimentally proven, proposed stability models are able to predict the critical ‎depth of cut at both low and high cutting speeds.‎

description: Privatization and commercialization of airports in recent years are drawing a different picture in the aeronautical industry. Airport benchmarking shows the accommodation and performance of airports in the evolution of the market and the new requirements that they have to face. AENA manages a wide and heterogeneous network of airports. There are 46 airports divided into three categories and with particularities due to their geographical location or the competitive environment where they are located. This paper analyzes the technical efficiency and its determinants of the 39 commercial airports of the AENA network between the years 2011-2014. To do this, two benchmarking techniques, SFA and DEA, are used, with a two-stage analysis. The average efficiency of the network is between 75-79\%. The results with the two techniques are similar with a correlation of 0.67. With regard to the commercial part of the network, AENA has a high margin for improvement because it is below the world and European average. AENA must focus on the development of the commercial area and the introduction of competition within the network to improve the technical efficiency of regional airports mainly.

description: The multi-nucleon transfer reaction between 136Xe beam and 198Pt target at the beam energy 7 MeV/u was studied using the large acceptance spectrometer VAMOS++ coupled with the newly installed second arm time-of-flight and delayed $γ$-ray spectrometer CATLIFE (Complementary Arm for Target LIke FragmEnts). The CATLIFE detector is composed of a large area multi-wire proportional chamber and the EXOGAM HPGe clover detectors with an ion flight length of 1230 mm. Direct measurement of the target-like fragments (TLF) and the delayed $γ$-rays from the isomeric state helps to improve TLF identification. The use of the velocity of TLFs and the delayed $γ$-ray demonstrate the proof of principle and effectiveness of the new setup.
Clouds and red giants interacting with the base of AGN jets

description: Extragalactic jets are formed close to supermassive black-holes in the center of galaxies. Large amounts of gas, dust, and stars cluster in the galaxy nucleus, and interactions between this ambient material and the jet base should be frequent, having dynamical as well as radiative consequences. This work studies the dynamical interaction of an obstacle, a clump of matter or the atmosphere of an evolved star, with the innermost region of an extragalactic jet. Jet mass-loading and the high-energy outcome of this interaction are briefly discussed. Relativistic hydrodynamical simulations with axial symmetry have been carried out for homogeneous and inhomogeneous obstacles inside a relativistic jet. These obstacles may represent a medium inhomogeneity or the disrupted atmosphere of a red giant star. Once inside the jet, an homogeneous obstacle expands and gets disrupted after few dynamical timescales, whereas in the inhomogeneous case, a solid core can smoothen the process, with the obstacle mass-loss dominated by a dense and narrow tail pointing in the direction of the jet. In either case, matter is expected to accelerate and eventually get incorporated to the jet. Particles can be accelerated in the interaction region, and produce variable gamma-rays in the ambient matter, magnetic and photon fields. The presence of matter clumps or red giants into the base of an extragalactic jet likely implies significant jet mass-loading and slowing down. Fast flare-like gamma-ray events, and some level of persistent emission, are expected due to these interactions.

description: The formation of the photo-polaronic excitons in ABO_{3} perovskite type oxides has been detected experimentally by means of the photoinduced electron paramagnetic resonance studies of KTa_{0.998}Nb_{0.012}O_{3} crystals. The corresponding microwave X-band spectrum at T < 10 K consists of a narrow, nearly isotropic signal located at g ~ 2 and a strongly anisotropic component. The first signal, which has a rich structure due to hyperfine interactions with the lattice nuclei, is attributed to the single trapped charge carriers: the electrons and/or the holes. The anisotropic spectrum is caused by the axial centers oriented along the C_{4} pseudo-cubic principal crystalline axes. The spectrum angular dependence can be described well by an axial center with S = 1, g_{\parallel) = 0.82, g_{\perp} = 0.52 and D = 0.44 cm^{-1}. The anisotropic spectrum is attributed to the Nb^{4+}-O^{-} polaronic excitons. The temperature dependence of the anisotropic component is characterized by two activation energies: the internal dynamics activation E_{a1} = 3.7\pm0.5 meV, which makes the EPR spectrum unobservable above 10 K, and the destruction energy E_{a2} = 52\pm4 meV. By comparing the anisotropic photo-EPR spectrum and the photoinduced optical absorption temperature dependencies, we found that the Nb^{4+}-O^{-} polaronic excitons also manifested themselves via the ~0.7 eV wide absorption band arising under UV light excitation in the weakly concentrated KTaO_{3}:Nb crystals.

description: The Ewald summation technique is generalised to power-law 1/|r|^k potentials in three-, two- and one-dimensional geometries with explicit formulae for all the components of the sums. The cases of short-range, long-range and "marginal" interactions are treated separately. The jellium model, as a particular case of a charge-neutral system, is discussed and the explicit forms of the Ewald sums for such system are presented. A generalised form of the Ewald sums for a noncubic (nonsquare) simulation cell for three- (two-) dimensional geometry is obtained and its possible field of application is discussed. A procedure for the optimisation of the involved parameters in actual simulations is developed and an example of its application is presented.

description: We develop high temperature series expansions for $\ln{Z}$ and the uniform structure factor of the spin-half Heisenberg model on the hyperkagome lattice to order $β^{16}$. These expansions are used to calculate the uniform susceptibility ($χ$), the entropy ($S$), and the heat capacity ($C$) of the model as a function of temperature. Series extrapolations of the expansions converge well down to a temperature of approximately $J/4$. A comparison with the experimental data for Na$_4$Ir$_3$O$_8$ shows that its magnetic susceptibility is reasonably well described by the model with an exchange constant $J\approx 300 K$, but there are also additional smaller terms present in the system. The specific heat of the model has two peaks. The lower temperature peak, which is just below our range of convergence contains about 40 percent of the total entropy. Despite being a 3-dimensional lattice, this model shares many features with the kagome lattice Heisenberg model and the material must be considered a strong candidate for a quantum spin-liquid.

The Siren topos: definition and signification
Creators: name: Sullivan, Martha Elisabeth
Publisher: name: No Publisher Supplied
Year: 2023

description: The Siren topos appears across most genres of Western music of the past three centuries. Strictly speaking, it may be defined as a conspicuously wide upward leap within a melodic line, one that crosses registral boundaries, ending on a note that is very high in the range of the voice or other instrument, or in some other way requires virtuosity to perform. Other musical details confirm its identity: it usually leaps from a weak beat into a strong one, and traverses a change of harmony, or occurs unaccompanied. The narrative features of the Siren topos—including its various associations with water, women, magic, singing, alterity, and above all its use as an invitation—give it unusual semiotic weight for a single gesture. As a sign, it may arise from several locations: the musical score, the character performing it in a song or opera, the voice and body of the performer, or the larger repertoire of melodic gestures to which it may be compared. The Siren topos typically occurs in vocal music, but may also be transported to instrumental contexts while still retaining semiotic power. The upward leap disrupts the melodic line within which it occurs while it functions as a signifier for various objects, including separation from a thing desired; compelling invitations; danger; sensuality; female vocality and the corresponding discomfort a listener may associate with powerful female voices; and alterity, including such categories as the feminine, the supernatural (which is a proxy for various real-world alterities), the Orientalized Other, the Black, the poor, and the queer (including those of marginalized gender identities, sexual orientations, and sexual and romantic practices). This dissertation delineates the circumstances that support reading the gesture as a strong signifier, as well as situations in which the leap fails to function as the Siren topos. The information and analyses here will be useful to music theorists interested in topic analysis and semiotics, but also to performers—especially singers—who are interested in developing new interpretive tools. Because the Siren topos has as its object/referent/signified something typically female, my description of it also opens the path to new discourses around gender. And as the topic sometimes occurs in music that flips gender binaries, queers them, or engages in camp practices, the Siren topos will also be a useful tool for composers, analysts, and performers who want to embrace queerness as a part of their musical practice.

description: The Gothic, a nearly 900-year cultural tradition beginning with the first gothic edifice during the twelfth century and expanding into a culture spanning a multitude of literary and artistic mediums, generations of writers, and a range of geographies, demographics, and destinations, encompasses many facets of the human experience: lust, fear, envy, ambition, greed, horror, deceit, disgust, and love, to name a few. This thesis addresses what previous scholarship that analyzes the gothic has failed to note: the gothic’s unique positionality to present for interpretation the passing as human experience that reflects the lived experiences of a long- under-acknowledged identity group: The Passing Other. Drawing on Freudian theories of the uncanny, this thesis examines the Passing Other's experience in Victorian and contemporary representations of vampires, werewolves, demons, and manufactured monsters.
The bulk correlation length and the range of thermodynamic Casimir forces at Bose-Einstein condensation

description: The relation between the bulk correlation length and the decay length of thermodynamic Casimir forces is investigated microscopically in two three-dimensional systems undergoing Bose-Einstein condensation: the perfect Bose gas and the imperfect mean-field Bose gas. For each of these systems, both lengths diverge upon approaching the corresponding condensation point from the one-phase side, and are proportional to each other. We determine the proportionality factors and discuss their dependence on the boundary conditions. The values of the corresponding critical exponents for the decay length and the correlation length are the same, equal to 1/2 for the perfect gas, and 1 for the imperfect gas.

description: Let $η_t$ be a Poisson point process of intensity $t\geq 1$ on some state space $\Y$ and $f$ be a non-negative symmetric function on $\Y^k$ for some $k\geq 1$. Applying $f$ to all $k$-tuples of distinct points of $η_t$ generates a point process $ξ_t$ on the positive real-half axis. The scaling limit of $ξ_t$ as $t$ tends to infinity is shown to be a Poisson point process with explicitly known intensity measure. From this, a limit theorem for the the $m$-th smallest point of $ξ_t$ is concluded. This is strengthened by providing a rate of convergence. The technical background includes Wiener-Itô chaos decompositions and the Malliavin calculus of variations on the Poisson space as well as the Chen-Stein method for Poisson approximation. The general result is accompanied by a number of examples from geometric probability and stochastic geometry, such as Poisson $k$-flats, Poisson random polytopes, random geometric graphs and random simplices. They are obtained by combining the general limit theorem with tools from convex and integral geometry.

description: Some students' expectations and points of view related to the Artificial Intelligence course are explored and analyzed in this study. We anonymous collected answers from 58 undergraduate students out of 200 enrolled in the Computer Science specialization. The answers were analysed and interpreted using thematic analysis to find out their interests and attractive and unattractive aspects related to the Artificial Intelligence study topic. We concluded that students are interested in Artificial Intelligence due to its trendiness, applicability, their passion and interest in the subject, the potential for future growth, and high salaries. However, the students' expectations were mainly related to achieving medium knowledge in the Artificial Intelligence field, and men seem to be more interested in acquiring high-level skills than women. The most common part that wasn't enjoyed by the students was the mathematical aspect used in Artificial Intelligence. Some of them (a small group) were also aware of the Artificial Intelligence potential which could be used in an unethical manner for negative purposes. Our study also provides a short comparison to the Databases course, in which students were not that passionate or interested in achieving medium knowledge, their interest was related to DB usage and basic information.

description: The dynamics of the DNA denaturation is studied using the Peyrard-Bishop-Dauxois model. The denaturation rate of double stranded polymers decreases exponentially as function of length below the denaturation temperature. Above Tc, the rate shows a minimum, but then increases as function of length. We also examine the influence of sequence and solvent friction. Molecules having the same number of weak and strong base-pairs can have significantly different opening rates depending on the order of base-pairs.

Circadian Clock

description: Most living organisms on Earth are photosensitive, including humans, and they get influenced by the solar day and night cycles created by the axial rotation of the Earth. The diurnal exposure of ultraviolet radiation (UVR) from the Sun is responsible for various skin-related diseases, including melanoma and non-melanoma skin cancers in humans. Evolutionarily, our skin has developed various protective biological mechanisms against the harmful effects of UVR, including nucleotide excision repair (NER) and melanin. In the past, the circadian clock has been shown to regulate NER and cell cycle processes, where their ability to protect from UVR changes according to the time of the day. However, the growing trend of erratic work schedule and feeding behavior has been shown to profoundly affect our circadian clock, making our body vulnerable to a host of environmental stressors, including UVR. Similar to NER, melanin, which is synthesized in melanocytes, is regarded as one of the most effective skin protectants against UVR damage, as it absorbs excess solar UVR and protects against genomic insults. Over the years, multiple signaling pathways have been shown to influence melanin biosynthesis by directly controlling the expression on a master regulator of melanogenesis, the microphthalmia-associated transcription factor (MITF). MITF is a basic helix-loop-helix melanoma proto-oncogene known to modulate critical melanocyte mechanisms by transcriptionally controlling MITF’s target genes. As the role of the transcriptional influence of the skin circadian clock on DNA repair in protecting the cells from environmental genotoxic stress is well established, what remains unknown is its connection with melanin pigmentation through MITF and a possible feedback loop that has the potential to affect the circadian clock back. Therefore, my thesis tries to understand both the clock's properties in melanocytes and their role in protecting against the solar UVR through MITF and how clock disruption mediated by MITF contributes to melanoma initiation/progression.

description: We consider one-dimensional chain of coupled linear and nonlinear oscillators with long-range power wise interaction defined by a term proportional to 1/|n-m|^{α+1}. Continuous medium equation for this system can be obtained in the so-called infrared limit when the wave number tends to zero. We construct a transform operator that maps the system of large number of ordinary differential equations of motion of the particles into a partial differential equation with the Riesz fractional derivative of order α, when 0

description: In the context of the present dissertation an attempt will be made to focus on the commentary of two award-winning puzzle video games and whether they can be used as teaching and learning mediums especially among adolescents and young adults. The first one is called The Witness (2016) by Thekla, Inc. and is considered to be an open-world puzzle game where the trial-and-error movements of the players constitute its main design element. The other game is called Baba is you (2019) by Arvi Teikari where the players are presented with a one-screen puzzle consisting of various objects, characters, and movable word tiles in addition to being given the opportunity to adjust the game rules on the basis of their personal interests. Moreover, this theoretical approach aims to showcase how the two puzzle video games chosen can not only benefit the way students’ certain cognitive skills function but also prove to be effective tools that can be integrated in an educational environment.

Επιπλέον, αυτή η θεωρητική προσέγγιση στοχεύει στο να αναδείξει πως αυτά τα δύο παιχνίδια που έχουν επιλεχθεί μπορούν να βελτιώσουν τον τρόπο που ορισμένες γνωστικές ικανότητες των μαθητών λειτουργούν και αν μπορούν να αποδειχθούν αποτελεσματικά εργαλεία τα οποία μπορούν να ενσωματωθούν σε ένα εκπαιδευτικό περιβάλλον.
Mathematical modeling of the fatigue life following rim indentation test in aluminum alloy wheels

description: The volume of components manufactured from cast aluminum alloys in both the aerospace and automotive industries has seen a tremendous rise in the past 10 years. In the automotive industry, cast wheels also provide aesthetically appealing designs for the consumers, which is an important factor for their increased demand. The cyclic nature of in-service loading in some applications makes fatigue performance a key design consideration. Manufacturers use standardized testing procedures (SAE J328) to assess the fatigue life of wheels for regular driving or cornering conditions. Recently, a leading North American wheel manufacturing company has begun testing the radial fatigue life of wheels following rim indentation. The development of this test has highlighted the need for a tool to support the wheel design process that is capable of predicting the fatigue life of cast components following permanent deformation. A considerable amount of research work has already been conducted on establishing the effects of microstructure and casting defects on the fatigue life of cast aluminum alloy A356. However, there has been limited work published on the effects of initial plastic deformation on the fatigue life of cast alloy A356. Thus, the current research project aims to quantify the effects of initial plastic strain on the fatigue life of automotive wheels manufactured from A356. Specifically, the research aims to enhance the understanding of the impact of rim indentation on the fatigue life of a wheel. A finite element model was developed to predict the deformation occurring during application of a static load during the rim indentation test. The residual stress distribution occur¬ring after the T6 heat treatment process was used as an input to the rim indentation model. The model was then extended to calculate the stress state of the wheel under radial fatigue test conditions. Lab-scale experiments were performed to characterize the fatigue behavior of alloy A356 following different amounts of pre-strain (plastic strain). This data was used to develop an empirical relationship to relate the fatigue life to initial plastic strain and the cyclic stress state. Industrial-scale rim indentation and radial fatigue tests were used to validate the overall model predictions.

description: A systematic study of energy spectra throughout the rare-earth region (even-even nuclei from $_{58}$Ce to $_{74}$W) is carried out in the framework of the interacting boson model (IBM), leading to an accurate description of the spherical-to-deformed shape transition in the different isotopic chains. The resulting IBM Hamiltonians are then used for the calculation of nuclear charge radii (including isotope and isomer shifts) and electric monopole transitions with consistent operators for the two observables. The main conclusion of this study is that an IBM description of charge radii and electric monopole transitions is possible for most of the nuclei considered but that it breaks down in the tungsten isotopes. It is suggested that this failure is related to hexadecapole deformation.

description: In this paper we discuss the astronomical search for water vapor in order to understand the disposition of water in all its phases throughout the process of star and planet formation. Our ability to detect and study water vapor has recently received a tremendous boost with the successful launch and operations of the Herschel Space Observatory. Herschel spectroscopic detections of numerous transitions in a variety of astronomical objects, along with previous work by other space-based observatories, will be threaded throughout this contribution. In particular, we present observations of water tracing the earliest stage of star birth where it is predominantly frozen as ice. When a star is born the local energy release by radiation liberates ices in its surrounding envelope and powers energetic outflows that appear to be water factories. In these regions water plays an important role in the gas physics. Finally, we end with an exploration of water in planet forming disks surrounding young stars. The availability of accurate molecular data (frequencies, collisional rate coefficients, and chemical reaction rates) are crucial to analyze the observations at each of these steps.
