Futuristic person re-identification over internet of biometrics things (IoBT): Technical potential versus practical reality
No full textThis article presents an overview of how person re-identification can be achieved over the Internet of Biometric Things (IoBT) architecture by enabling technologies and protocols for multimodal biometric authentication leveraging futuristic cues. The Internet of Things (IoT), as a new era of technology, extends the power of the internet to a whole range of devices, thus reshaping our daily lives in the best possible way. IoT-enabled intelligent surveillance devices are the most indispensable part of public safety and security in smart cities. These IoT devices generate a vast amount of surveillance traffic that is practically impossible for humans to continuously monitor and/or analyze. Person re-identification (PRId), which aims to track and recognize a person in a multi-camera scene is an important feature of visual surveillance systems in IoT infrastructures and can utilize the aforementioned traffic. This is where the concept of IoBT, which is a cloud-centric biometric authentication architecture composed of these IoT-enabled devices for the PRId system, comes into play. This article conceptualizes an overview of interpreting various futuristic cues on the IoT platform for achieving PRId. We highlight some opportunities and key challenges of implementing this futuristic PRId system on IoBT. The article is a proof of concept of the technical potential of such implementation in the near future

First observation of and search for exotic baryons in systems
No full textThe process γγ→pp¯K+K- and its intermediate processes are measured for the first time using a 980 fb-1 data sample collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. The production of pp¯K+K- and a Λ(1520)0 (Λ¯(1520)0) signal in the pK- (p¯K+) invariant mass spectrum are clearly observed. However, no evidence for an exotic baryon near 1540 MeV/c2, denoted as Θ(1540)0 (Θ¯(1540)0) or Θ(1540)++ (Θ(1540)--), is seen in the pK- (p¯K+) or pK+ (p¯K-) invariant mass spectra. Cross sections for γγ→pp¯K+K-, Λ(1520)0p¯K++c.c. and the products σ(γγ→Θ(1540)0p¯K++c.c.)B(Θ(1540)0→pK-) and σ(γγ→Θ(1540)++p¯K-+c.c.)B(Θ(1540)++→pK+) are measured. We also determine upper limits on the products of the χc0 and χc2 two-photon decay widths and their branching fractions to pp¯K+K- at the 90% credibility level
Study of the p–p–K + and p–p–K - dynamics using the femtoscopy technique
No full textThe interactions of kaons (K) and antikaons (K ̄) with few nucleons (N) were studied so far using kaonic atom data and measurements of kaon production and interaction yields in nuclei. Some details of the three-body KNN and K ̄ NN dynamics are still not well understood, mainly due to the overlap with multi-nucleon interactions in nuclei. An alternative method to probe the dynamics of three-body systems with kaons is to study the final state interaction within triplet of particles emitted in pp collisions at the Large Hadron Collider, which are free from effects due to the presence of bound nucleons. This Letter reports the first femtoscopic study of p–p–K + and p–p–K - correlations measured in high-multiplicity pp collisions at s = 13 TeV by the ALICE Collaboration. The analysis shows that the measured p–p–K + and p–p–K - correlation functions can be interpreted in terms of pairwise interactions in the triplets, indicating that the dynamics of such systems is dominated by the two-body interactions without significant contributions from three-body effects or bound states

The following branching fractions are measured: B(B+→pΛ¯K+K-)=(4.10-0.43+0.45±0.50)×10-6, B(B+→p¯ΛK+K+)=(3.70-0.37+0.39±0.44)×10-6, B(ηc→pΛ¯K-+c.c.)=(2.83-0.34+0.36±0.35)×10-3 and B(B+→pΛ¯ϕ)=( 7.95±2.09±0.77)×10-7, where c.c. denotes the corresponding charge-conjugation process. The intermediate resonance decays are excluded in the four-body decay measurements. We also find evidence for B(ηc→Λ(1520)Λ¯+c.c.)=(3.48±1.48±0.46)×10-3 and B(B+→Λ(1520)Λ¯K+)=( 2.23±0.63±0.25)×10-6. No significant signals are found for J/ψ→Λ(1520)Λ¯+c.c. and B+→Λ¯(1520)ΛK+; we set the 90% confidence level upper limits on their decay branching fractions as <1.80×10-3 and <2.08×10-6, respectively
Study of the p–p–K and p–p–K dynamics using the femtoscopy technique
No full textThe interactions of kaons (K) and antikaons (K)
with few nucleons (N) were studied so far using kaonic
atom data and measurements of kaon production and interaction yields in nuclei. Some details of the three-body KNN
and KNN dynamics are still not well understood, mainly
due to the overlap with multi-nucleon interactions in nuclei.
An alternative method to probe the dynamics of three-body
systems with kaons is to study the final state interaction
within triplet of particles emitted in pp collisions at the Large
Hadron Collider, which are free from effects due to the presence of bound nucleons. This Letter reports the first femtoscopic study of p–p–K+ and p–p–K− correlations measured in high-multiplicity pp collisions at √s = 13 TeV
by the ALICE Collaboration. The analysis shows that the
measured p–p–K+ and p–p–K− correlation functions can be
interpreted in terms of pairwise interactions in the triplets,
indicating that the dynamics of such systems is dominated
by the two-body interactions without significant contributions from three-body effects or bound states
