Vectors are living organisms that can transmit infectious pathogens between humans, or from animals to humans. Many of these vectors are bloodsucking insects, which ingest disease-producing microorganisms during a blood meal from an infected host (human\r\n or animal) and later transmit it into a new host, after the pathogen has replicated. Often, once a vector becomes infectious, they are capable of transmitting the pathogen for the rest of their life during each subsequent bite/blood meal.\r\n 


Vector-borne diseases are human illnesses caused by parasites, viruses and bacteria that are transmitted by vectors. Every year there are more than 700,000 deaths from diseases such as malaria, dengue, schistosomiasis, human African trypanosomiasis, leishmaniasis,\r\n Chagas disease, yellow fever, Japanese encephalitis and onchocerciasis.\r\n

The following table is a non-exhaustive list of vector-borne disease, ordered according to the vector by which it is transmitted. The list also illustrates the type of pathogen that causes the disease in humans.

WHO Secretariat provides strategic, normative and technical guidance to countries and development partners for strengthening vector control as a fundamental approach based on GVCR to preventing disease and responding to outbreaks. Specifically WHO responds to vector-borne diseases by:

A crucial element in reducing the burden of vector-borne diseases is behavioural change. WHO works with partners to provide education and improve public awareness, so that people know how to protect themselves and their communities from mosquitoes, ticks, bugs, flies and other vectors.

The pathogens, vectors and hosts associated with vector-borne diseases are highly responsive to the environments they inhabit. This means that changes in temperature and precipitation as a result of climate change can have significant impacts on the spread of vector-borne diseases.

Temperature change can affect the behaviour of vectors. For example, increased temperatures change the biting behaviour of mosquitoes, reducing the effectiveness of barriers such as bed nets.

However, it can be challenging to attribute these impacts to climate change, as other factors are also at play. For example, changes in land-use, control measures and human movement can also influence the distribution of vectors and spread of disease.

The geographic distribution of dengue, a mosquito-borne viral infection, has expanded globally since the 1990s. And while this can be largely attributed to human movement so far, by 2030, one of the dominant causes of expansion of these vectors is predicted to be climate change.

Similarly, malaria is a climate-sensitive vector-borne disease that responds to short-term changes in rainfall, humidity, and temperature. In the highlands of Colombia and Ethiopia, temperature increases of just 0.2C per decade have been associated with the spread of malaria to higher elevations.

Ticks are another vector capable of transmitting pathogens, including zoonotic viruses like Lyme disease and tick-borne encephalitis. Tick expansion is promoted by the warmer winters in the last decade due to global warming.

This result is the first statistically significant measurement, as far as we are aware, of the axial vector form factor on free protons without nuclear corrections or other theoretical assumptions. Theoretical uncertainties from the carbon background have been minimized by data-driven methods. By providing a precise and reliable prediction for the charged-current elastic scattering from nucleons, neutrino measurements on higher Z nuclei can benefit from better constrained nucleon effects to expose the nuclear effects. The method developed in this study will enable future experiments with hydrogen content in the target18,19 to make further measurements of the axial form factor. Future experiments with intrinsic three-dimensional capability would be able to observe the directions of low-energy neutron candidates, and improve the low Q2 measurement with more statistics.

Calculating the integrated cross-section in each bin needs to account for the muon phase space cuts described above. The effect of the phase space restriction is manifested as a restricted range of neutrino energy available in the selected sample at each Q2 point, ultimately reducing the differential cross-section at each Q2 bin because the acceptance-corrected event rate is divided by the fully integrated neutrino flux for this measurement. Extended Data Fig. 8 (right) illustrates the accepted neutrino energy at each Q2. Therefore, obtaining a fit of FA requires the convolution of equation (4) with the antineutrino flux from the RHC configuration of the NuMI34 neutrino beam with the Q2-dependent energy cutoff. The vector form factors used in this analysis are parameterized from electron scattering data31 used commonly by neutrino Monte Carlo generators42,49,58.

The axial vector form factor is also fitted using the z expansion59 formalism. We adopt the procedure of a fit to deuterium data by Meyer et al.24. The z expansion for FA is a polynomial of z with coefficients ak reproduced here for convenience.

The development of the vector could make gene therapy for sickle cell disease much more effective and pave the way for wider use of it as a curative approach for the painful, life-threatening blood disorder. Sickle cell disease affects about 100,000 people in the United States and millions worldwide.

In word2vec, a distributed representation of a word is used. Take a vector with several hundred dimensions (say 1000). Each word is representated by a distribution of weights across those elements. So instead of a one-to-one mapping between an element in the vector and a word, the representation of a word is spread across all of the elements in the vector, and each element in the vector contributes to the definition of many words.

The vectors are very good at answering analogy questions of the form a is to b as c is to ?. For example, man is to woman as uncle is to ? (aunt) using a simple vector offset method based on cosine distance.

Word vectors with such semantic relationships could be used to improve many existing NLP applications, such as machine translation, information retrieval and question answering systems, and may enable other future applications yet to be invented.

The Semantic-Syntatic word relationship tests for understanding of a wide variety of relationships as shown below. Using 640-dimensional word vectors, a skip-gram trained model achieved 55% semantic accuracy and 59% syntatic accuracy.

The context words form the input layer. Each word is encoded in one-hot form, so if the vocabulary size is V these will be V-dimensional vectors with just one of the elements set to one, and the rest all zeros. There is a single hidden layer and an output layer.

To solve this problem, an intuition is to limit the number of output vectors that must be updated per training instance. One elegant approach to achieving this is hierarchical softmax; another approach is through sampling.

Copy the received form and paste the copy to the front (Cmd/Ctrl + C; Cmd/Ctrl + F). Fill the upper form with vertical gradient which consists of two shades of grey or any other color if you want to have a colorful torn paper vector.

The torn paper vector effect is ready! This is a fairly popular technique in graphic design which can be used, for example, for option banners or infographics. As a sample I included a colorful infographics template in a torn paper vector style from Shutterstock. e24fc04721
