Models of language trained on very large corpora have been demonstrated useful for natural language processing. As fixed artifacts, they have become the object of intense study, with many researchers probing'' the extent to which they acquire and rea
dily demonstrate linguistic abstractions, factual and commonsense knowledge, and reasoning abilities. Recent work applied several probes to intermediate training stages to observe the developmental process of a large-scale model (Chiang et al., 2020). Following this effort, we systematically answer a question: for various types of knowledge a language model learns, when during (pre)training are they acquired? Using RoBERTa as a case study, we find: linguistic knowledge is acquired fast, stably, and robustly across domains. Facts and commonsense are slower and more domain-sensitive. Reasoning abilities are, in general, not stably acquired. As new datasets, pretraining protocols, and probes emerge, we believe that probing-across-time analyses can help researchers understand the complex, intermingled learning that these models undergo and guide us toward more efficient approaches that accomplish necessary learning faster.

Most of the villages and rural towns, in general, and in Latakia, in particular, suffer from
poor transport organizing and Serving of people so that travelling has become a great
suffering for most people. After studying the transport situation bet
ween Jableh and
Latakia, we found that this city suffers from transport problems like other cities. This is
because of transport poor management and regulation including timing, the number of
vehicles available and inability to meet demand, which causes a deterioration in service
quality.
The research provided a comprehensive method to evaluate the performance of public
transport on the road by evaluating travel time, the journey speed, and the buses volume
and frequency. Considering these indicators as a criterion for evaluating the performance
of public transport to determine the most effective factors regarding the quality of
performance of public transport and improve this performance in future. A field and
practical study of the research has been conducted, which includes selecting of study sites,
collecting engineering and traffic data, designing of questionnaires and distributing them
on random passengers and drivers working on Jableh - Lattakia transportation road to find
out their opinions. Then the data has been inserted into SPSS Statistics Base program for
analyzing the results.
The research has concluded that the performance of public transport between Jableh and
Latakia is generally weak, and the largest proportion of passengers depend on their
mobility on minibuses, which does not satisfy the required transportation level. Therefore,
a range of solutions has been developed depending on local conditions which will ease the
burden of mobility and raise the transportation performance level.
This paper has been carried out to Study the correlation
between Vitreous Humor Potassium Levels and the Time of
bleeding-caused Death, and to find a formula proposed to calculate
the post mortem interval (PMI) by finding the regression equation.
The present study was prepared to assess the level of
potassium in the vitreous humor fluid, to calculate the post mortem
interval (PMI) by finding the regression equation and to study the
effects of environmental factors like temperature and humidity and
age and sex on it.
This paper deals with the performance study of the self-excited
induction generator when driven by wind turbine for producing
electrical energy. This was done by modeling both the induction
generator and the wind turbine using the Matlab program,
and
depending on the general theory of electrical machines. method for
this system by studying together the mechanical characteristics of
the wind turbine and operating characteristics of the induction
generator.
This paper aims to use Static Synchronous Compensators (STATCOMs) in two
cases combined or distributed, where it act in the first case as one compensator at
one placement of electrical network, for the same required power of studied network,
and d
istributed compensators as multi-STACOM with suitable powers in the second
case where they are connected at the best placements of studied network, for
improving critical clearing time of IEEE-9 nodes test system and its transient
stability.
Carried out the experiment in the laboratory through the experience
of the patch where they were both studying the effect of pH (5.5-7-
8.5), and the time of contact between the solution and the soil
(05.01.10 / d) and the concentration of the sol
ution of the metal
chromium (13.4-22.84-47.57 mg / l) in the adsorption kinetics and
chrome. The results of the patch test showed that the amount of
chromium adsorbed from the aqueous solution increases with time,
and be this quantity greater in the first minute, and in all degrees of
the pH of the solution Whatever the chromium concentration in the
initial solution, as well as the degree of adsorption or removal ratio,
and chrome amount adsorbed from The solution is greater when the
pH of the solution is 8.5, and that whatever the initial concentration
of the solution, as well as the degree of adsorption or removal ratio.
This study aimed to study the economic efficiency of producing
biogas from manure dairy cows, through cost and revenue account,
using some of economic indicators.
In this research, we have derived an analytical equation gives
dependency of the total gas pressure to operation time for halogen
self-quenched GM counter tubes and organic vapor or gas selfquenched
GM counter tubes. This equation indicates that t
he gas
pressure exponentially decreases as the operation time increases, at
constant temperature of tube and constant activity that this tube
exposed to.
