Large pre-trained language models such as BERT have been the driving force behind recent improvements across many NLP tasks. However, BERT is only trained to predict missing words -- either through masking or next sentence prediction -- and has no kn
owledge of lexical, syntactic or semantic information beyond what it picks up through unsupervised pre-training. We propose a novel method to explicitly inject linguistic information in the form of word embeddings into any layer of a pre-trained BERT. When injecting counter-fitted and dependency-based embeddings, the performance improvements on multiple semantic similarity datasets indicate that such information is beneficial and currently missing from the original model. Our qualitative analysis shows that counter-fitted embedding injection is particularly beneficial, with notable improvements on examples that require synonym resolution.
We propose a rolling version of the Latent Dirichlet Allocation, called RollingLDA. By a sequential approach, it enables the construction of LDA-based time series of topics that are consistent with previous states of LDA models. After an initial mode
ling, updates can be computed efficiently, allowing for real-time monitoring and detection of events or structural breaks. For this purpose, we propose suitable similarity measures for topics and provide simulation evidence of superiority over other commonly used approaches. The adequacy of the resulting method is illustrated by an application to an example corpus. In particular, we compute the similarity of sequentially obtained topic and word distributions over consecutive time periods. For a representative example corpus consisting of The New York Times articles from 1980 to 2020, we analyze the effect of several tuning parameter choices and we run the RollingLDA method on the full dataset of approximately 4 million articles to demonstrate its feasibility.
The research provides a comparison between two methods for treating osteoarthritis. In the knee joint using platelet-rich plasma injections after or without arthroscopy, the study included 100 cases every fifty of them were treated in one way and the
results were evaluated after surgery and the researcher reached the following results. Treatment with platelet-rich plasma injections after arthroscopy provided an advantage in terms of pain reduction and reduced joint effusion in the knee, improvement of the ability to rest on the limb (walking), and a marked reduction in the severity of symptoms and signs of degeneration was noted.
The objective of this study was to compare the effect of using intravaginal sponges with intramuscular (IM) injection of prostaglandin hormone within the reproductive season and their effect on Lambing rate and birth rate in Awassi ewes. Thirty ewes
were equally divided into two groups (G1 and G2). Intravaginal sponges impregnated with 60 mg of Medroxy
Progesterone Acetate (MAP) were inserted into the ewes of the first group for 14 days, and were injected at the time of the withdrawal of sponges with 500 IU of equine Chorionic Gonadotrophin (eCG) at the first group ewes (G1). The ewes in second group (G2) were
injected with double dose of 125 μg of prostaglandin (PGF2α) intramuscularly (IM) at 9 days apart. The ewes were naturally mated with fertile rams (ram / 5 ewes). The results showed that there were significant differences between groups (G1 and G2) in the Lambing rate (93.33% vs. 73.33%). The ewes of group (G1) outperformed the ewes of group (G2) in the
percentage of twin births (42.86% vs. 18.18%), and the birth rate (1.43 vs. 1.18) with significant differences (P<0.05). We conclude from the study that treating ewes by using intravaginal sponges with eCG injection was better than the method of prostaglandin
injection in raising the Lambing rate and birth rate in Syrian Awassi ewes, within the local Syrian conditions
Interdental Papilla deficiency may occur due to many factors such as
traumatic oral hygiene procedure, plaque associated lesions and
diverging roots following orthodontic treatment. Many of invasive and
non-invasive techniques have been suggested
to reconstruct the
deficient interdental papilla. Treatment using hyaluronic acid gel
injection is the most recent non-invasive technique which
characterized by its easily application as well as avoidance exposing
the patient to surgical procedures. The purpose of this study was to
evaluate the efficiency of repeated cross-linked hyaluronic acid gel
injection in management of deficient interdental papilla at the esthetic
zone after six months of treatment.

Elastin and collagen loss from the dermal layer is essential cause for wrinkles in
the face. Dermal fillers is the solution for this problem and this study compared clinical improvement
degree and the duration of correction between hyaluronic acid (Matrigel) versus bovine collagen (Zyplast)
for the correction of nasolabial fold.
