description: The light trapping design in this work indicates an increase of the effective path length by as much as a
factor of 21. Simulations show that Jsc of 88%Ge content Ge:Si solar cell below Si with light trapping can be 130%
higher than that without light trapping. Experimentally an increase in optical path length of 17X was achieved on 88%Ge
content Ge:Si solar cells which were grown on low cost c-Si substrates by reduced pressure chemical vapor deposition
(RPCVD) technology. A Jsc of 7.91mA/cm2 was obtained below Si at one sun. It is 120% higher than that of cells
without light trapping. Below Si at 30 suns, the efficiency of 88%Ge content Ge:Si solar cell with light trapping reached
1.37% which is 60% of the modeled efficiency maximum.

description: Here we consider a one-dimensional $q$-state Potts model with an external magnetic field and an anisotropic interaction that selects neighboring sites that are in the spin state 1. The present model exhibits an unusual behavior in the low-temperature region, where we observe an anomalous vigorous change in the entropy for a given temperature. There is a steep behavior at a given temperature in entropy as a function of temperature, quite similar to first-order discontinuity, but there is no jump in the entropy. Similarly, second derivative quantities like specific heat and magnetic susceptibility also exhibit a strong acute peak rather similar to second-order phase transition divergence, but once again there is no singularity at this point. Correlation length also confirms this anomalous behavior at the same given temperature, showing a strong and sharp peak which easily one may confuse with a divergence. The temperature where occurs this anomalous feature we call pseudo-critical temperature. We have analyzed physical quantities, like correlation length, entropy, magnetization, specific heat, magnetic susceptibility, and distant pair correlation functions. Furthermore, we analyze the pseudo-critical exponent that satisfy a class of universality previously identified in the literature for other one-dimensional models, these pseudo-critical exponents are: for correlation length $ν=1$, specific heat $α=3$ and magnetic susceptibility $μ=3$.

Onset of criticality in hyper-auxetic polymer networks

description: Against common sense, auxetic materials expand or contract perpendicularly when stretched or compressed, respectively, by uniaxial strain, being characterized by a negative Poisson's ratio $ν$. The amount of deformation in response to the applied force can be at most equal to the imposed one, so that $ν=-1$ is the lowest bound for the mechanical stability of solids, a condition here defined as "hyper-auxeticity". In this work, we numerically show that ultra-low-crosslinked polymer networks under tension display hyper-auxetic behavior at a finite crosslinker concentration. At this point, the nearby mechanical instability triggers the onset of a critical-like transition between two states of different densities. This phenomenon displays similar features as well as important differences with respect to gas-liquid phase separation. Since our model is able to faithfully describe real-world hydrogels, the present results can be readily tested in laboratory experiments, paving the way to explore this unconventional phase behavior.

description: We study the dissipative dynamics of one-dimensional fermions, described in terms of the sine-Gordon model in its free massive boson or semi-classical limit, while keeping track of forward scattering processes. The system is prepared in the gapped ground state, and then coupled to environment through local currents within the Lindblad formalism. The heating dynamics of the system is followed using bosonization. The single particle density matrix exhibits correlations between the left and right moving particles. While the density matrix of right movers and left movers is translationally invariant, the left-right sector is not, corresponding to a translational symmetry breaking charge density wave state. Asymptotically, the single particle density matrix decays exponentially with exponent proportional to $-γt|x|Δ^2$ where $γ$ and $Δ$ are the dissipative coupling and the gap, respectively. The charge density wave order parameter decays exponentially in time with an interaction independent decay rate. The second Rényi entropy grows linearly with time and is essentially insensitive to the presence of the gap.

description: In order to address the scattered availability of information on photovoltaic (PV) modules, inverters
and systems in the Netherlands a new organization was founded mid 2011: Stichting Monitoring Zonnestroom
(Foundation Monitoring Photovoltaics). As one of its first tasks, a market inventory study was performed in October
2011, with updates in April and July 2012. A clear decrease in average module price (including VAT) was observed
of about 30% between October 2011 and July 2012; inverter price was somewhat stable over this period. Average
system price now is at 1.53 Euro/Wp and 1.57 Euro/Wp for flat and tilted systems, respectively, excluding
installation. Installation cost are found to vary between 0.6 and 0.2 Euro/Wp for small (<1 kWp) and large (50 kWp)
systems, respectively. Total price of typical system sizes in the Netherlands of 0.6, 2.5, 5, and 50 kWp are determined
to be 2.74, 2.07, 1.70, and 1.60 Euro/Wp. Levelized cost of electricity then are calculated to be 0.269, 0.203, 0.167,
and 0.157 Euro/kWh using a 6% interest rate, 900 kWh/kWp system yield, 25 year lifetime, and 1% annual operation
and maintenance cost. As consumers are presently charged 0.23 Euro/kWh in the Netherlands for their household
electricity use, grid parity for systems >2.5 kWp has been reached for the first time.

description: Magnetic reconnection is explored on the Terrestrial Reconnection Experiment (TREX) for asymmetric inflow conditions and in a configuration where the absolute rate of reconnection is set by an external drive. Magnetic pileup enhances the upstream magnetic field of the high density inflow, leading to an increased upstream Alfven speed and helping to lower the normalized reconnection rate to values expected from theoretical consideration. In addition, a shock interface between the far upstream supersonic plasma inflow and the region of magnetic flux pileup is observed, important to the overall force balance of the system, hereby demonstrating the role of shock formation for configurations including a supersonically driven inflow. Despite the specialised geometry where a strong reconnection drive is applied from only one side of the reconnection layer, previous numerical and theoretical results remain robust and are shown to accurately predict the normalized rate of reconnection for the range of system sizes considered. This experimental rate of reconnection is dependent on system size, reaching values as high as 0.8 at the smallest normalized system size applied.

description: We observe the failure process of a fiber bundle model with a variable stress release range, $γ$, higher the value of $γ$ lower the stress release range. By tuning $γ$ from low to high, it is possible to go from the mean-field (MF) limit of the model to local load sharing (LLS) where local stress concentration plays a crucial role. In the MF limit, the avalanche size $s$ and energy $E$ emitted during the avalanche are highly correlated producing the same distribution for both $P(s)$ and $Q(E)$: a scale-free distribution with a universal exponent -5/2. With increasing $γ$, the model enters the LLS limit. In this limit, due to the presence of local stress concentration such correlation $C(γ)$ between $s$ and $E$ decreases where the nature of the decreases depends highly on the dimension of the bundle. In 1d, the $C(γ)$ stars from a high value for low $γ$ and decreases towards zero when $γ$ is increased. As a result, $Q(E)$ and $P(s)$ are similar at low $γ$, an exponential one, and then $Q(E)$ becomes power-law for high-stress release range though $P(s)$ remains exponential. On the other hand, in 2d, the $C(γ)$ decreases slightly with $γ$ but remains at a high value. Due to such a high correlation, the distribution of both $s$ and $E$ is exponential in the LLS limit independent of how large $γ$ is.

description: The evolution of languages closely resembles the evolution of haploid organisms. This similarity has been recently exploited \cite{GA,GJ} to construct language trees. The key point is the definition of a distance among all pairs of languages which is the analogous of a genetic distance. Many methods have been proposed to define these distances, one of this, used by glottochronology, compute distance from the percentage of shared ``cognates''. Cognates are words inferred to have a common historical origin, and subjective judgment plays a relevant role in the identification process. Here we push closer the analogy with evolutionary biology and we introduce a genetic distance among language pairs by considering a renormalized Levenshtein distance among words with same meaning and averaging on all the words contained in a Swadesh list \cite{Sw}. The subjectivity of process is consistently reduced and the reproducibility is highly facilitated. We test our method against the Indo-European group considering fifty different languages and the two hundred words of the Swadesh list for any of them. We find out a tree which closely resembles the one published in \cite{GA} with some significant differences.

Silicon Solar Cell Improvements

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 596-599
description: Despite significant cost advantages, Cu has not yet replaced Ag as the main component of contemporary state-of-theart
crystalline silicon solar cells. The main reason is the technical difficulty of obtaining well-adhered contacts
without contamination of the bulk silicon. Also, complex metallization schemes often include deep silicidation of
metal/silicon interfaces, thus requiring additional process steps for localized diffusions such as selective emitters or
back surface fields. TetraSun has developed a manufacturing technology that overcomes these problems and
successfully employs Cu plating for cost reduction. The TetraCell technology is alignment-free, compatible with ntype
crystalline silicon and can be used in bifacial module designs. So far, 21% cell efficiency has been achieved on
125x125 mm wafers. Cells were assembled into modules with conventional soldering technology and accelerated
reliability tests were conducted and passed IEC 61215 criteria.

description: The detections of gravitational waves (GWs) from binary neutron star (BNS) systems and neutron star--black hole (NSBH) systems provide new insights into dense matter properties in extreme conditions and associated high-energy astrophysical processes. However, currently information about NS equation of state (EoS) is extracted with very limited precision. Meanwhile, the fruitful results from the serendipitous discovery of the $γ$-ray burst alongside GW170817 show the necessity of early warning alerts. Accurate measurements of the matter effects and sky location could be achieved by joint GW detection from space and ground. In our work, based on two example cases, GW170817 and GW200105, we use the Fisher information matrix analysis to investigate the multiband synergy between the space-borne decihertz GW detectors and the ground-based Einstein Telescope (ET). We specially focus on the parameters pertaining to spin-induced quadrupole moment, tidal deformability, and sky localization. We demonstrate that, (i) only with the help of multiband observations can we constrain the quadrupole parameter; and (ii) with the inclusion of decihertz GW detectors, the errors of tidal deformability would be a few times smaller, indicating that many more EoSs could be excluded; (iii) with the inclusion of ET, the sky localization improves by about an order of magnitude. Furthermore, we have systematically compared the different limits from four planned decihertz detectors and adopting two widely used waveform models.

description: Village health volunteers (VHVs) are the backbone of primary healthcare in many low-and-middle-income countries, including Thailand, where healthcare professionals are scarce. Previous studies looking at their role have been broader and lacked a specific mental health focus. In 2019, Thailand introduced a policy endorsing a recovery orientation in mental health care, however, the potential for VHVs to implement the approach remains underexplored. This study aims to: [1] describe VHVs’ mental health practices, [2] explore stakeholders’ perspectives on these practices, and [3] understand stakeholders’ views on their potential to deliver recovery-oriented community care. Method This exploratory qualitative study involved nineteen semi-structured interviews conducted between August 2023 and March 2024 in a rural subdistrict of Northern Thailand. Participants included ten VHVs, four nurses, four caregivers, and one individual with mental health conditions. Purposeful and snowball sampling techniques were used. Reflexive thematic analysis was used to analyse interview data. Official documents related to VHVs’ job descriptions, training, and recruitment policies were also examined to understand the scope of the role. Results The analysis identified three main themes: [1] Mental health practices and roles perceptions, highlighting variability among VHVs; [2] Organisational constraints on mental health practice in the community, demonstrating limited policy support and training for VHVs; and [3] Factors influencing the implementation of recovery-oriented approaches by VHVs, including barriers such as stigma and workload, and enabling factors such as specialist training and professional support.

description: This paper shows a new bonding method for mechanically stacked multi-junction solar cells. Our
strategy is the combination of conductive nanoparticle alignments and van der Waals bonding. Conductive
nanoparticles, such as Pd, were aligned through the use of a self-assembled block copolymer template, and the
domain size of 50 nm and the concentration of 1×1010 cm-2 were realized. With this method, reductions of bonding
resistance and optical absorption loss were simultaneously attained for the use of mechanically stacked solar cells. It
is possible to apply this method for various sorts of photovoltaic materials, such as Si, Ge, GaAs, InP, and CuInGaSe.
As a demonstrative case, we examined a GaAs (Eg-1.4 eV)/InGaAsP (Eg-1.15 eV) two-junction solar cell fabricated
with the new bonding method, and the total efficiency of 11.8% was achieved which was in good agreement with the
theoretically predicted value. The bonding resistance was estimated to be 3.1 Ωcm2. These results suggested that this
bonding method is highly useful for mechanically stacked multi-junction solar cells. The efficiency can be potentially
improved over 30% by the appropriate combinations of solar cells under current matching.

Gamma shape mixtures for heavy-tailed distributions

description: An important question in health services research is the estimation of the proportion of medical expenditures that exceed a given threshold. Typically, medical expenditures present highly skewed, heavy tailed distributions, for which (a) simple variable transformations are insufficient to achieve a tractable low-dimensional parametric form and (b) nonparametric methods are not efficient in estimating exceedance probabilities for large thresholds. Motivated by this context, in this paper we propose a general Bayesian approach for the estimation of tail probabilities of heavy-tailed distributions, based on a mixture of gamma distributions in which the mixing occurs over the shape parameter. This family provides a flexible and novel approach for modeling heavy-tailed distributions, it is computationally efficient, and it only requires to specify a prior distribution for a single parameter. By carrying out simulation studies, we compare our approach with commonly used methods, such as the log-normal model and nonparametric alternatives. We found that the mixture-gamma model significantly improves predictive performance in estimating tail probabilities, compared to these alternatives. We also applied our method to the Medical Current Beneficiary Survey (MCBS), for which we estimate the probability of exceeding a given hospitalization cost for smoking attributable diseases. We have implemented the method in the open source GSM package, available from the Comprehensive R Archive Network.

Silicon Solar Cell Characterization and Modelling

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 1217-1220
description: Silicon wafer solar cells with a local back surface field (“LBSF”) formed by aluminium are currently
intensively investigated for industrial application. The non-metallised rear surface regions of this structure are
passivated by a dielectric film, whereby this dielectric film receives line or point shaped openings for contact
formation, e.g. by laser ablation. An issue that is typically observed in screen-printed Al-LBSF solar cells is the
formation of voids at the rear contact between the Si substrate and the Al rear contact [1], [2], especially when using
narrow line widths or small-diameter point contacts. These voids significantly increase the series resistance of the
cells, as they reduce the Si-Al contact area, and moreover reduce the surface passivation quality of the local contacts
as the Al-LBSF diffusion profile is affected. In this work a reduction in the thickness of the rear Al layer is proposed
to reduce the lateral diffusion of Si and therefore reduce the void formation. We report on Al-LBSF solar cells with
thermally evaporated, screen-printed and sputtered Al of various thicknesses as the rear metal contact. The impact on
the void and Al p+ layer formation is studied by photoluminescence imaging and scanning electron microscopy.
Finally, Al-LBSF solar cells are fabricated using various thicknesses of the rear Al metal contact.

description: We present investigations of a class of solutions of Einstein's field equations close to the family of lambda-Taub-NUT spacetimes. The studies are done using a numerical code introduced by the author elsewhere. One of the main technical complication is due to the S3-topology of the Cauchy surfaces. Complementing these numerical results with heuristic arguments, we are able to yield some first insights into the strong cosmic censorship issue and the conjectures by Belinskii, Khalatnikov, and Lifschitz in this class of spacetimes. In particular, the current investigations suggest that strong cosmic censorship holds in this class. We further identify open issues in our current approach and point to future research projects.

description: We have found the light-induced conductivity enhancement in ZnO layers, incorporated as front
electrodes of hydrogenated-amorphous-silicon (a-Si:H)/microcrystalline-silicon (μc-Si:H) tandem solar cells. The
light-induced change has been observed particularly in ZnO:B layers deposited by low-pressure chemical vapor
deposition. In all the ZnO:B layers with different B concentrations, the increase in carrier concentration (5×1019 cm-3)
as well as mobility (>5 cm2/Vs) under the light illumination of AM1.5G (100 mW/cm2) has been confirmed. The
carrier properties of the ZnO:B layers have been characterized by spectroscopic ellipsometry (SE) using the Drude
analysis. The SE results were compared with those obtained from the Hall measurements, and these results revealed
that the light-induced change occurs predominantly in the ZnO intragrains, rather than the grain boundaries. The
increase in the ZnO carrier concentration by the light soaking has been found to reduce the short-circuit current in the
μc-Si:H bottom cell due to the increase in free carrier absorption.

description: We report a temperature-dependent Raman scattering investigation of thin film rare earth nickelates SmNiO3, NdNiO3 and Sm0.60Nd0.40NiO3, which present a metal-to-insulator (MI) transition at TMI and an antiferromagnetic-paramagnetic Neel transition at TN. Our results provide evidence that all investigated samples present a structural phase transition at TMI but the Raman signature across TMI is significantly different for NdNiO3 (TMI = TN) compared to SmNiO3 and Sm0.60Nd0.40NiO3 (TMI =/ TN). It is namely observed that the paramagnetic-insulator phase (TN < T < TMI) in SmNiO3 and Sm0.60Nd0.40NiO3 is characterized by a pronounced softening of one particular phonon band around 420 cm-1. This signature is unusual and points to an important and continuous change in the distortion of NiO6 octahedra (thus the Ni-O bonding) which stabilizes upon cooling at the magnetic transition. The observed behaviour might well be a general feature for all rare earth nickelates with TMI =/ TN and illustrates intriguing coupling mechanism in the TMI > T > TN regime.

description: The goal of the present work is to obtain a reliable estimate of the masses of the ground and radially excited states of fully-heavy tetraquark systems. In order to do this, we use a nonrelativistic model of tetraquarks which are assumed to be compact and consist of diquark-antidiquark pairs. This nonrelativistic model is composed of Hulthen potential, a linear confining potential and spin-spin interaction. We computed ground, first, and second radially excited $cc\bar{c}\bar{c}$ and $bb\bar{b}\bar{b}$ tetraquark masses. It was found that predicted masses of ground states of $cc\bar{c}\bar{c}$ and $bb\bar{b}\bar{b}$ tetraquarks are significantly higher than the thresholds of the fall-apart decays to the lowest allowed two-meson states. These states should be broad and are thus difficult to observe experimentally. First radially excited states are considerably lower than their corresponding (2S-2S) two-meson thresholds. We hope that our study may be helpful to the experimental search for ground and excited $cc\bar{c}\bar{c}$ and $bb\bar{b}\bar{b}$ tetraquark states.

Silicon Solar Cell Characterization and Modelling

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 1221-1224
description: In recent years, excellent efficiency results with n-type all-back-contact (ABC) silicon wafer solar cells
have been demonstrated. One of the main advantages of ABC solar cells is the elimination of shading by the front
metal grid, resulting in potentially higher short-circuit current densities. However, due to the requirement that both
the emitter and back-surface-field regions be laid out on the rear surface, such that they must form a mutually
interrupting pattern, ABC cells are susceptible to electrical shading and relatively high lateral resistive losses. This
work studies the impact of these losses in screen-printed ABC solar cells, based on test cells with a rear structure
which is more simply defined, but commensurate with full area devices. One-sun I-V measurements were taken with
various aperture areas to quantify the electrical shading and lateral resistance losses. A detailed loss analysis at the
maximum power point confirmed that these losses are the two major loss mechanisms of the investigated ABC test
cells. Analysis of an example 125-mm pseudo-square cell demonstrated that these losses can be reduced by proper
design of the rear pattern.
NNLO Vertex Corrections in charmless hadronic B decays: Imaginary part

description: We compute the imaginary part of the 2-loop vertex corrections in the QCD Factorization framework for hadronic two-body decays as B -> pi pi. This completes the NNLO calculation of the imaginary part of the topological tree amplitudes and represents an important step towards a NNLO prediction of direct CP asymmetries in QCD Factorization. Concerning the technical aspects, we find that soft and collinear infrared divergences cancel in the hard-scattering kernels which demonstrates factorization at the 2-loop order. All results are obtained analytically including the dependence on the charm quark mass. The numerical impact of the NNLO corrections is found to be significant, in particular they lead to an enhancement of the strong phase of the colour-suppressed tree amplitude.

description: To this day, the coronavirus is still spreading on a large scale in the world and continuously mutating, making the prevention and control of the epidemic worse. The scientific traceability of the virus is of great significance to solving the problem of the transmission of the disease. At present, there are multiple evidences showing that the Coronavirus originated in the United States, or that the virus leaked due to laboratory accidents and caused an epidemic. Due to the negligence and deliberate concealment of the U.S. government, COVID-19 was mistakenly transmitted as an "e-cigarette disease" or flu in its early stages, the cold chain transportation and U.S. military activities in the United States were the main media for the invasion and spread of COVID-19 outside the United States. Facing the increasingly severe challenge of the Coronavirus epidemic, the US government has hidden the truth of the epidemic, led a politicized investigation of the origin of the Coronavirus, retagged and stigmatized the virus under the pretext of the epidemic, and used it as a political tools to attack other countries, especially to Chinese. This completely contrary to the spirit of science, interferes with global traceability cooperation, undermines global unity in fighting the epidemic, and creates and exacerbates estrangement and confrontation is bound to be cast aside by the people of the world.
Crossing the cosmological constant line in a dilatonic brane-world model with and without curvature corrections

description: We construct a new brane-world model composed of a bulk -with a dilatonic field-, plus a brane -with brane tension coupled to the dilaton-, cold dark matter and an induced gravity term. It is possible to show that depending on the nature of the coupling between the brane tension and the dilaton this model can describe the late-time acceleration of the brane expansion (for the normal branch) as it moves within the bulk. The acceleration is produced together with a mimicry of the crossing of the cosmological constant line (w=-1) on the brane, although this crossing of the phantom divide is obtained without invoking any phantom matter neither on the brane nor in the bulk. The role of dark energy is played by the brane tension, which reaches a maximum positive value along the cosmological expansion of the brane. It is precisely at that maximum that the crossing of the phantom divide takes place. We also show that these results remain valid when the induced gravity term on the brane is switched off.

description: For the high-efficiency type of silicon solar cells, hetero-junction with intrinsic amorphous
thin-film (HIT) solar cells has been confirmed to achieve 23.7% by Sanyo Electric. From the
theoretical viewpoint, how to further enhance the efficiencies of the silicon solar cells for the next
generation is a most critical issue. Based on the a-Si heterojunction structure, very high Voc over
740 mV have been demonstrated. Therefore, Interdigitated back contact silicon heterojunction solar
cells (IBC-SHJ) have the potential for high open voltage and high short current density due to all
back contact design. Several groups reported the progress in this field, and the efficiencies ranges
from 13.9% to 20%. However, IBC based on heterojunction solar cell still performs low F.F. values
in the recent years. Therefore, we propose a new structure based on boron diffused emitter
combined with IBC-SHJ to greatly improve the conversion efficiencies, especially for reducing
series resistances. The key issue to improve efficiency is to resolve the interface resistance between
c-Si and a-Si. For n-type wafer, the large valence band offset between c-Si and a-Si results in large
resistive loss and lower efficiencies. Boron-doped a-Si is also difficult to have denser carrier density.
Therefore, by incorporation the boron emitter between i-a-Si and c-Si can greatly reduce valence
band offset and enhance the silicon solar efficiency.

No Ward-Takahashi identity violation for an Abelian tensorial group field theories with closure constraint

description: This paper aims at investigating the nonperturbative functional renormalization group for tensorial group field theories with nontrivial kinetic action and closure constraint. We consider the quartic melonic just-renormalizable $[U(1)]^6$ model and show that due to this closure constraint the first order Ward-Takahashi identity takes the trivial form as for the models with propagators proportional to identity. We then construct the new version of the effective vertex expansion applicable to this class of models, which in particular allows to close the hierarchical structure of the flow equations in the melonic sector. As a consequence, there are no additional constraints on the flow equations, and then we can focus on the existence of the physical Wilson-Fisher fixed-points in the symmetric phase.

Silicon Solar Cell Improvements

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 1494-1497
description: Shinsung Solar Energy R&D center works on a high efficiency solar cell. One of the technologies is based on the selective emitter from laser doping technique and Ni/Cu plated contact.
Now, Shinsung Solar Energy achieved the energy conversion efficiency of 19.64% (confirmed by Fraunhofer ISE) at the 6inch wafer by the front side selective emitter by laser doping and plated Ni/Cu metal contacts by LIP(Light Induced Plating). We use 6 inch standard commercial grade 0.5 - 3 Ω-cm boron-doped CZ silicon wafers. In this case we have to solve the problem for plating which is shunting on the edge side of the wafer. In this paper we represent 3 different ways to get a lightly doped emitter; back side oxide masking, single side (back side) etching, and single side doping using ion implantation process. And we optimize the aspect ratio of plated Cu contact by varying the HF dipping, Ni plating by LIP and Cu plating by LIP condition.

description: The set of all non-increasing nonnegative integers sequence $π=$ ($d(v_1),$ $d(v_2),$ $...,$ $d(v_n)$) is denoted by $NS_n$. A sequence $π\in NS_n$ is said to be graphic if it is the degree sequence of a simple graph $G$ on $n$ vertices, and such a graph $G$ is called a realization of $π$. The set of all graphic sequences in $NS_n$ is denoted by $GS_n$. A graphical sequence $π$ is potentially $H$-graphical if there is a realization of $π$ containing $H$ as a subgraph, while $π$ is forcibly $H$-graphical if every realization of $π$ contains $H$ as a subgraph. Let $K_k$ denote a complete graph on $k$ vertices. Let $K_{m}-H$ be the graph obtained from $K_{m}$ by removing the edges set $E(H)$ of the graph $H$ ($H$ is a subgraph of $K_{m}$). This paper summarizes briefly some recent results on potentially $K_{m}-G$-graphic sequences and give a useful classification for determining $σ(H,n)$.
