Anisotropic nonlinear elasticity in a spherical bead pack: influence of the fabric anisotropy

description: Stress-strain measurements and ultrasound propagation experiments in glass bead packs have been simultaneously conducted to characterize the stress-induced anisotropy under uniaxial loading. These measurements, realized respectively with finite and incremental deformations of the granular assembly, are analyzed within the framework of the effective medium theory based on the Hertz-Mindlin contact theory. Our work shows that both compressional and shear wave velocities and consequently the incremental elastic moduli agree fairly well with the effective medium model by Johnson et al. [J. Appl. Mech. 65, 380 (1998)], but the anisotropic stress ratio resulting from finite deformation does not at all. As indicated by numerical simulations, the discrepancy may arise from the fact that the model doesn't properly allow the grains to relax from the affine motion approximation. Here we find that the interaction nature at the grain contact could also play a crucial role for the relevant prediction by the model; indeed, such discrepancy can be significantly reduced if the frictional resistance between grains is removed. Another main experimental finding is the influence of the inherent anisotropy of granular packs, realized by different protocols of the sample preparation. Our results reveal that compressional waves are more sensitive to the stress-induced anisotropy, whereas the shear waves are more sensitive to the fabric anisotropy, not being accounted in analytical effective medium models.

description: The electromagnetic transitions between ($J^{P}={3/2}^{+}$) and ($J^{P}={1/2}^{+}$) baryons are important decay modes to observe new hadronic states experimentally. For the estimation of these transitions widths, we employ a non-relativistic quark potential model description with color coulomb plus linear confinement potential. Such a description has been employed to compute the ground state masses and magnetic moments of the single heavy flavor baryons. The magnetic moments of the baryons are obtained using the spin-flavor structure of the constituting quark composition of the baryon. Here, we also define an effective constituent mass of the quarks (ecqm) by taking into account the binding effects of the quarks within the baryon. The radiative transition widths are computed in terms of the magnetic moments of the baryon and the photon energy. Our results are compared with other theoretical models.

description: Guébie (also known as Gaɓogbo) is a Kru language spoken by about 7,000 people in the Gagnoa prefecture in southwest Côte d’Ivoire. Guébie people are primarily subsistence farmers, growing cassava, rice, corn, and plantains. Many also grow cocoa and rubber for profit. In the past 20 years there has been an influx of outsiders settling in Guébie villages, new roads have been developed which lead to easier access to nearby cities, and new schools have been built where French is taught and use of Guébie is not allowed. For these reasons, among others, French and Bété, the local language of wider communication, are replacing Guébie in many domains of daily use, and Guébie is not always spoken in the home and passed on to children.

Year: 2020

description: Kera’a is a Trans-Himalayan language1 traditionally spoken by the Kera’a (Idu Mishmi) in the Lower Dibang and Dibang Valley districts of Arunachal Pradesh, located in disputed territory between India and China. The language is still widely-spoken in the valley by up to 16,000 speakers total, but ongoing cultural, economic and demographic change in the region due to outside forces has led to partial disruption of generational transmission. There are some previously published resources on the language such as phrasebooks, but little audiovisual material is available and no comprehensive grammatical description exists. This report is based on initial field trips to the area in the second half of 2019 and early 2020. ________________________________________________________________________ 1 The Trans-Himalayan family is more commonly termed Sino-Tibetan or Tibeto-Burman; however, these terms presuppose a certain genealogical organisation and are biased towards literate communities. I have chosen to use the more neutral ‘Trans-Himalayan’ following van Driem (2014) and Post (2019), among others.

description: We propose a model for Diffusive Shock Acceleration (DSA) in which stochastic magnetic fields in the shock precursor are generated through purely fluid mechanisms of a so-called small-scale dynamo. This contrasts with previous DSA models that considered magnetic fields amplified through cosmic ray streaming instabilities; i.e., either by way of individual particles resonant scattering in the magnetic fields, or by macroscopic electric currents associated with large-scale cosmic ray streaming. Instead, in our picture, the solenoidal velocity perturbations that are required for the dynamo to work are produced through the interactions of the pressure gradient of the cosmic ray precursor and density perturbations in the inflowing fluid. Our estimates show that this mechanism provides fast growth of magnetic field and is very generic. We argue that for supernovae shocks the mechanism is capable of generating upstream magnetic fields that are sufficiently strong for accelerating cosmic rays up to around 10^16 eV. No action of any other mechanism is necessary.

description: Besides the liver, hepatitis C virus (HCV) infection also affects kidney allografts. The aim of this study was to longitudinally evaluate viscoelasticity changes in the liver and in kidney allografts in kidney transplant recipients (KTRs) with HCV infection after treatment with direct-acting antiviral agents (DAAs). Fifteen KTRs with HCV infection were treated with DAAs (daclatasvir and sofosbuvir) for 3 months and monitored at baseline, end of treatment (EOT), and 3 (FU1) and 12 (FU2) months after EOT. Shear-wave speed (SWS) and loss angle of the complex shear modulus (φ), reflecting stiffness and fluidity, respectively, were reconstructed from multifrequency magnetic resonance elastography data with tomoelastography post-processing. After virus elimination by DAAs, hepatic stiffness and fluidity decreased, while kidney allograft stiffness and fluidity increased compared with baseline (hepatic stiffness change at FU1: -0.14 m/s, p < 0.01, and at FU2: -0.11 m/s, p < 0.05; fluidity at FU1: -0.05 rad, p = 0.04 and unchanged at FU2: p = 0.20; kidney allograft stiffness change at FU1: +0.27 m/s, p = 0.01, and at FU2: +0.30 m/s, p < 0.01; fluidity at FU1 and FU2: +0.06 rad, p = 0.02). These results suggest the restoration of mechanically sensitive structures and functions in both organs. Tomoelastography can be used to monitor the therapeutic results of HCV treatment non-invasively on the basis of hepatic and renal viscoelastic parameters.

description: Fast algorithms for the computation of $N$-body problems can be broadly classified into mesh-based interpolation methods, and hierarchical or multiresolution methods. To this last class belongs the well-known fast multipole method (FMM), which offers O(N) complexity. This paper presents an extensible parallel library for $N$-body interactions utilizing the FMM algorithm, built on the framework of PETSc. A prominent feature of this library is that it is designed to be extensible, with a view to unifying efforts involving many algorithms based on the same principles as the FMM and enabling easy development of scientific application codes. The paper also details an exhaustive model for the computation of tree-based $N$-body algorithms in parallel, including both work estimates and communications estimates. With this model, we are able to implement a method to provide automatic, a priori load balancing of the parallel execution, achieving optimal distribution of the computational work among processors and minimal inter-processor communications. Using a client application that performs the calculation of velocity induced by $N$ vortex particles, ample verification and testing of the library was performed. Strong scaling results are presented with close to a million particles in up to 64 processors, including both speedup and parallel efficiency. The library is currently able to achieve over 85% parallel efficiency for 64 processors. The software library is open source under the PETSc license; this guarantees the maximum impact to the scientific community and encourages peer-based collaboration for the extensions and applications.

description: Southern Alta people are hunter-gatherers living along the tributaries of rivers in the Sierra Madre mountains in the northern Philippines. Southern Alta (agy), locally known as Kabulowan, is a Philippine Negrito language, and a coordinate branch of Meso-Cordilleran subgroup of the Northern Luzon family. Dialectal variations are present in different communities and the speakers are multilingual. The language vitality rating using the EGIDS scale is 6b ‘threatened’. The elders have considerable knowledge of their language, beliefs, customs, and traditions. Intermarriage, illegal trading, changes in socio-cultural lifestyle, religious orientation, other forms of political and cultural repression, and the use of Tagalog have been accelerating language attrition. No written history has been recorded although digitized religious commentaries are available. Because of the fast rate of language attrition, the production of audio and/or video documentation for further linguistic analysis and archiving is a high priority.

We investigate this possibility in the Fe8 molecule where magnetization jumps are known to occur at discreet magnetic field values. We found energy bursts each time the molecule undergoes a magnetization jump, confirming their quantum nature. A series of tests indicated that photons carry out the energy, and that indeed these photons obey the elementary conditions for super-radiance.

description: In this study, two natural waxes, beeswax (BW) and sunflower wax (SFW), are combined with their hydrolyzed variants to deliberately alter the waxes’ composition. The properties of the produced oleogels with different wax inclusion levels (4%, 8%, 12%, and 16% w/w) are investigated after defined intervals (2 days, 7 days, 3 weeks, and 3 months). To do so, the gels are monitored via penetrometry, microscopy, and calorimetry. Although the gels do not show any significant difference during storage in the micrographs, the calorimetric and firmness data reveal meaningful results. The heat of dissolution increases in every system investigated, indicating post‐crystallization processes. Due to different solubilities of wax components, the critical gelling concentration is determined and the solid wax content is retrieved to further address the structure efficiency (S.E.). It is demonstrated that although the quantity of solids over time increases, the scaffolding effectiveness decreases in most cases. Only SFW, most likely due to sintering, shows an increase in S.E. over the storage time. Identified synergistic effects in BW and hydrolyzate mixtures decrease with increasing storage time. This work aims to contribute to a better understanding of the behavior of wax‐based oleogels upon storage. Practical Applications: Although much is known about the gel properties of wax‐based oleogels at short‐term, the behavior over the storage period remains largely unresolved. However, this behavior is immensely important for a real application in fast and slow moving consumer goods. After all, products should always have the same consumer‐relevant properties when stored at variable time frames. This applies to both food and pharmaceutical products. Knowledge of the behavior of wax‐based oleogels in terms of a time‐dependent change can help to choose a targeted product design and ensure product quality and consumer satisfaction.

description: Forecasting AI progress is essential to reducing uncertainty in order to appropriately plan for research efforts on AI safety and AI governance. While this is generally considered to be an important topic, little work has been conducted on it and there is no published document that gives a balanced overview of the field. Moreover, the field is very diverse and there is no published consensus regarding its direction. This paper describes the development of a research agenda for forecasting AI progress which utilized the Delphi technique to elicit and aggregate experts’ opinions on what questions and methods to prioritize. Experts indicated that a wide variety of methods should be considered for forecasting AI progress. Moreover, experts identified salient questions that were both general and completely unique to the problem of forecasting AI progress. Some of the highest priority topics include the validation of (partially unresolved) forecasts, how to make forecasts action-guiding, and the quality of different performance metrics. While statistical methods seem more promising, there is also recognition that supplementing judgmental techniques can be quite beneficial.

description: Iñapari is an Arawak language spoken by four siblings in the village of Sabaluyoc along the Las Piedras River in the department of Madre de Dios, Peru. In catalogs and other literature, Iñapari is often incorrectly classified as being (possibly) extinct. In response to the lack of information, an intensive five-week field research scenario in July 2019 was conducted with the primary goal of ascertaining the vitality of the language and if possible to collect information and resources on its morphosyntax. Information was recorded through elicitation, conversation, and naturalistic storytelling. This paper outlines the current language ecology and ongoing research on the language.

description: In this work, we prove that a positive secure degree of freedom is achievable for a large class of Gaussian channels as long as the channel is not degraded and the channel is fully connected. This class includes the MAC wire-tap channel, the 2-user interference channel with confidential messages, the 2-user interference channel with an external eavesdropper. Best known achievable schemes to date for these channels use Gaussian signaling. In this work, we show that structured codes outperform Gaussian random codes at high SNR when channel gains are real numbers.

title: Intratumoral Immunotherapy with NanoPulse Stimulation and anti-PD-L1-Functionalized Carbon Nanotubes in B16f10 Melanoma

Publisher: name: Old Dominion University Libraries

description: In two well characterized orthotopic rodent tumor models [1-3] NanoPulse Stimulation (NPS) provides an intratumoral immunotherapy by using the tumor as its own vaccine. NPS not only ablates many types of orthotopic and ectopic tumors in rats, mice and humans [4], but also induces immunogenic cell death [1, 5], activates T-cell-dependent immune responses, activates innate immunity, reverses immunosuppression, and can transform tumors into in situ vaccines [3]. However, not all tumor models readily response to NPS with immune induction and in situ vaccination. One of these is the mouseB16f10 melanoma model. To enhance NPS-induced immunity we will include another immunotherapy such as intratumoral delivery of anti- PD-L1 or anti-PD-1. However, immunotherapy requires two phases, a priming phase, and an effector phase [6]. Anti-PD-L1 therapy is believed to begin in the effector phase of immunity. By combining these therapies, NPS would provide the priming phase and anti-PD-L1 would enhance the NPS-induced effector phase. However, low anticancer treatment efficacy might be caused by a limited electric field coverage. A high electric field with a strength of as high as 50 kV/cm has been shown to be effective. Because of clinical consideration, such a high field is concerning. As a result, several additional modalities may be useful because of their high aspect ratio and strong conductivity. Multi-walled carbon nanotubes (MWCNTs), a type of new carbon allotrope, have been discovered to have field emission capability [7]. CNTs can amplify the electric field surrounding their tips due to their unique electronic properties, resulting in a localized high field zone [8]. When CNTs are combined with low-intensity electric pulses, stronger cell electro-responses are achieved [9]. Carbon nanotubes, on the other hand, have been shown to be cancer-targeted via both passive and active pathways, and to have a high level of tumor uptake [10]. Given these promising properties, MWCNTs will be used in combination with lower electric field stimulation to enhance cancer cell death and intratumoral antibody delivery.

We hypothesize that treating B16f10 melanoma cells with intratumoral MWCNT covalently functionalized with mouse PD-L1 antibody (MWCNT-anti-PDL1 or anti-PD-1) in combination with NPS treatment will reduce NPS conditions for efficacy [11], improve electrical safety and activate multiple anti-cancer and pro-immunity mechanisms in B16f10 melanoma. In vitro data with B16f10 melanoma cells indicate that NPS can reduce the lethality requirements for high NPS conditions by 3-5-fold.

It contributes to the quest to ‘Know your epidemic, know your response’, in particular in PNG contexts (UNAIDS 2007a: 10). The global endeavour to better ‘know your epidemic, know your response’ constitutes recognition that there are many diverse HIV epidemics and many different ways of responding to them. No single account captures their diversity. No single response keeps them at bay. Our understanding of an epidemic needs to guide us towards effective responses. So far this has not happened to any great extent. In 2007 globally some 2.5 million people became newly infected (UNAIDS 2007b: 1) ... " - page 1

description: We study the spectra of all long Gamma Ray Bursts (GRBs) of known redshift detected by the Fermi satellite. Their fluxes and fluences are large enough to allow a time dependent study of their spectral characteristics in the 8 keV-1 MeV energy range. We find that the peak energy Ep of their EL(E) spectrum correlates with the luminosity in a remarkable tight way within individual bursts. This time resolved Ep-Liso correlation is very similar for all the considered bursts, and has a slope and normalisation similar to the analogous Ep-Liso correlation defined by the time integrated spectra of different bursts detected by several different satellites. For a few of the considered GRBs, we could also study the behaviour of the Ep-Liso correlation during the rising and decaying phases of individual pulses within each burst, finding no differences. Our results indicate the presence of a similar physical mechanism, operating for the duration of different GRBs, linking tightly the burst luminosity with the peak energy of the spectrum emitted at different times. Such a physical mechanism is the same during the rise and decay phase of individual pulses composing a GRB. These results, while calling for a robust physical interpretation, strongly indicate that the Ep-Liso spectral energy correlation found considering the time integrated spectra of different bursts is real, and not the result of instrumental selection effects.

description: We present an analysis and classification of vector and scalar fluctuations in a D3/D7 brane setup at finite termperature and baryon density. The system is dual to an N=2 supersymmetric Yang-Mills theory with SU(N_c) gauge group and N_f hypermultiplets in the fundamental representation in the quenched approximation. We improve significantly over previous results on the quasinormal mode spectrum of D7 branes and stress their novel physical interpretation. Amongst our findings is a new purely imaginary scalar mode that becomes tachyonic at sufficiently low temperature and baryon density. We establish the existence of a critical density above which the scalar mode stays in the stable regime for all temperatures. In the vector sector we study the crossover from the hydrodynamic to the quasiparticle regime and find that it moves to shorter wavelengths for lower temperatures. At zero baryon density the quasinormal modes move toward distinct discrete attractor frequencies that depend on the momentum as we increase the temperature. At finite baryon density, however, the trajectories show a turning behavior such that for low temperature the quasinormal mode spectrum approaches the spectrum of the supersymmetric zero temperature normal modes. We interpret this as resolution of the singular quasinormal mode spectrum that appears at the limiting D7 brane embedding at vanishing baryon density.

description: In the wake of widespread and ongoing travel restrictions that began in early 2020 due to the COVID-19 pandemic, many documentary linguists worldwide shifted to remote work methods in order to continue or, in some cases, begin new projects. This pandemic situation has prompted questions about both methodological and ethical considerations in doing remote fieldwork. In this paper, we discuss the pros and cons of working remotely and discuss ways of working remotely based on our experiences working on projects in West Africa, northwest Amazonia, and Indonesia. We argue that elements of remote fieldwork should become a permanent part of linguistic fieldwork, but that such methods need to be considered in the context of decolonizing language documentation and centering the community’s needs and interests.

description: Activation of Transient Receptor Potential (TRP) channels can disrupt endothelial barrier function, as their mediated Ca2+ influx activates the CaM (calmodulin)/MLCK (myosin light chain kinase)-signaling pathway, and thereby rearranges the cytoskeleton, increases endothelial permeability and thus can facilitate activation of inflammatory cells and formation of pulmonary edema. Interestingly, TRP channel subunits can build heterotetramers, whereas heteromeric TRPC1/4, TRPC3/6 and TRPV1/4 are expressed in the lung endothelium and could be targeted as a protective strategy to reduce endothelial permeability in pulmonary inflammation. An update on TRP heteromers and their role in lung inflammation will be provided with this review.

description: Super-resolution microscopy in living cells can be restricted by the availability of small molecule probes, which only exist against few targets and genetically encoded tags. Here, we expand the applicability of live-cell STED by engineering cell-permeable and highly fluorescent nanobodies as intracellular targeting agents. To ensure bright fluorescent signals at low concentrations we used the concept of intramolecular photostabilization by ligating a fluorophore along with the photostabilizer trolox to the nanobody using expressed protein ligation (EPL). Furthermore, these semi-synthetic nanobodies are equipped with a cleavable cell-penetrating peptide for efficient cellular entry, which enables super-resolution imaging of GFP and mCherry, as well as two endogenous targets, nuclear lamins and the DNA replication and repair protein PCNA. We monitored cell division and DNA replication via confocal and STED microscopy thus demonstrating the utility of these new intracellular tools for functional analysis.

description: Cloaking using a volumetric structure composed of stacked two-dimensional transmission-line networks is verified with measurements. The measurements are done in a waveguide, in which an array of metallic cylinders is inserted causing a short-circuit in the waveguide. The metal cylinders are cloaked using a previously designed and simulated cloak that hides the cylinders and thus enables wave propagation inside the waveguide.

description: Artificial intelligence (AI) is a potentially disruptive tool for physics and science in general. One crucial question is how this technology can contribute at a conceptual level to help acquire new scientific understanding. Scientists have used AI techniques to rediscover previously known concepts. So far, no examples of that kind have been reported that are applied to open problems for getting new scientific concepts and ideas. Here, we present Theseus, an algorithm that can provide new conceptual understanding, and we demonstrate its applications in the field of experimental quantum optics. To do so, we make four crucial contributions. (i) We introduce a graph-based representation of quantum optical experiments that can be interpreted and used algorithmically. (ii) We develop an automated design approach for new quantum experiments, which is orders of magnitude faster than the best previous algorithms at concrete design tasks for experimental configuration. (iii) We solve several crucial open questions in experimental quantum optics which involve practical blueprints of resource states in photonic quantum technology and quantum states and transformations that allow for new foundational quantum experiments. Finally, and most importantly, (iv) the interpretable representation and enormous speed-up allow us to produce solutions that a human scientist can interpret and gain new scientific concepts from outright. We anticipate that Theseus will become an essential tool in quantum optics for developing new experiments and photonic hardware. It can further be generalized to answer open questions and provide new concepts in a large number of other quantum physical questions beyond quantum optical experiments. Theseus is a demonstration of explainable AI (XAI) in physics that shows how AI algorithms can contribute to science on a conceptual level.

description: During manned interplanetary missions, it is necessary to protect the crewmembers from the high energetic solar cosmic rays, mainly protons. A feasible solution consists of an active shield by means of a superconducting magnet. This magnetic lens is able to deflect the almost unidirectional solar cosmic rays away from the zone that can be occupied by crewmembers. Our study indicates that an air core toroid with inner diameter of 0.5 m and outer diameter of 3.5 m and a peak field of 2.80 T is suitable for astronaut protection. In this paper the detailed magnetic, mechanical and thermal design is presented, and different configurations for the superconducting coils are compared in order to find the most efficient and convenient solution in such a complex environment.

description: Data measured with a small Geiger counter for a period of approximately three months were analyzed to search for daily variation effects, after proper correction for the influence of the atmospheric pressure. Harmonic dial analysis for each individual day was carried out. The ratio of the measured flux between selected intervals within the 24 hours was also investigated. Methods and results are presented in the framework of educational studies involving high-school teams.

description: We introduce a class of maps from an affine flat into a Riemannian manifold that solve an elliptic system defined by the natural second order elliptic operator of the affine structure and the nonlinear Riemann geometry of the target. These maps are called affine harmonic. We show an existence result for affine harmonic maps in a given homotopy class when the target has non positive sectional curvature and some global non triviality condition is met. An example shows that such a condition is necessary. The analytical part is made difficult by the absence of a variational structure underlying affine harmonic maps. We therefore need to combine estimation techniques from geometric analysis and PDE theory with global geometric considerations.

description: Democratization in China has been receiving attention from all over the world. In the US, a large percentage of media reports about China contribute to report democratization related political issues. And as a mainland Chinese citizen living under an undemocratic regime, I have always felt compelled to do research on democratization in China society. This thesis describes a research study conducted to understand how Chinese people understand the notion of democracy, and with this notion how they perceive to democratize their society. The result of this research's analysis shows that Chinese people view democracy similar to a western notion; and they believe to help Chinese public to develop democratic cultural values is the most important in the course of democratizing China society. In common words, to democratize people would eventually democratize the society. This research works on data collected from the internet. The use of internet data is money saving and helps explore research on internet data. This research hopefully can provide a reference view for Chinese people themselves and people who care about China in understanding the current situation and predicting the prospect of democratization in China. And with a better understanding Chinese people might be able to take more strategic steps and earn strategic support from the world in the course of democratization of China's society.

description: They were continued, at National Institute of Nuclear Physics, Frascati National Laboratories-Italy, the systematic studies about detection of new elements, some even with isotopic composition different from natural one, after prolonged electrolysis of Pd wires. The electrolytic solution adopted is the, unusual, used from our experimental group since 1999. In short, it was a mixture of both heavy ethyl alcohol (C2H5OD at 90-95%) and water (D2O, at 10-5%), with Th salts at micromolar concentration and Hg at even lower concentration (both of spectroscopic purity). The liquid solutions, before use, were carefully vacuum distilled (and on line 100nm filtered) at low temperatures (30-40°C) and analysed by ICP-MS. The pH was kept quite mild (acidic at about 3-4). The cathode is Pd (99.9% purity) in the shape of long (60cm) and thin wires (diameter only 0.05mm). Before use, it is carefully cleaned and oxidised by Joule heating in air following a (complex) procedure from us continuously improved (since 1995). Before and after use, some pieces of it, about 50% of total length, are ICP-MS analysed. The anode is a Pt wire (purity>99.99%), 0.250mm diameter. The cell adopted is usually a borosilicate chemical glass (like SCHOTT-DURAN, Germany), filling volume about 750cc. Recently (since July 2004) an ultra-pure quartz cylinder (volume about 1050cc) was adopted in order to rule out possibilities of corrosion effects from the cell. The sample older and details of cell are made only of PTFE, as detailed at ICCF10 and ICCF11.
title: Impacts of Climate Change on Water Resources and Corresponding Adaptation Strategies of the Nam Ngum River Basin, Laos

description: The Nam Ngum River Basin (NNRB) in Laos has received attention of foreign investors due to high hydropower development potential and low per capita electricity consumption. The NNRB is rapidly developing due to its hydropower generation potentials while water demands will increase for agricultural and domestic purposes due to population increase and land-use changes. Water availability conditions will be affected with the increasing water demand and climate change may worsen the water availability conditions. Climate is often defined as the weather averaged over time whereas weather describes atmospheric conditions at a particular place and time in terms of air temperature, pressure, humidity, wind speed and rainfall. On regional scale, climate change impact assessment is crucial for water resource planning, management and decision making. First part of this study, reliable estimation of climatic variables is performed under climate change. Second part assess the changes in water resources regimes and sustainability conditions of agricultural and domestic water user sectors under climate change for “do nothing” option that are critical for strategic planning and to minimize the negative impacts. Third part assesses the long-term climate change trends, water allocation challenges and appropriate adaptation measures to minimize watershed impacts to achieve sustainability and long-term management goals. The major findings of this study shows (1) wetter and warmer climates especially in the latter part of the century indicating less water availability, (2) sustainability in meeting the water demands for agriculture and domestic use is affected under “do nothing” option, and (3) watershed scale adaptation measures improve the (1) hydropower generation, (2) sustainability conditions in agricultural and domestic water user sectors, and (3) flow regimes.
